Abstract
Because of substantial limitations in available national data, such as inconsistencies among surveys and small sample sizes, the increased prevalence of cannabis use among adolescents since recreational legalization has not been directly observed. Nevertheless, both usage frequency and product potency have significantly increased, alongside alternative routes of delivery to smoking, such as vaping cannabis. Moreover, certain populations may be especially vulnerable to the effects of legalization. Regardless of differing state-level cannabis legalization status, the adverse consequences of cannabis on youth have clear negative impacts on mental health, medical symptoms, educational outcomes, and increased risk of addiction to other substances.

Abstract
Background: The cannabis regulation landscape is ever evolving, and it may be difficult for parents to stay up to date. This study aimed to assess parental knowledge of recent cannabis legislation and cannabis health effects, as well as communication around cannabis use. Materials and Methods: Data were collected through the 2020 Voices of Child Health in Chicago Parent Panel Survey. Parents were asked about the veracity of statements on cannabis legislation and health effects, and about communication with their children. Descriptive statistics were calculated to characterize response frequencies. Rao-Scott chi-square test explored differences in the proportion of parents who answered all questions correctly or got at least one question wrong. Results: 75% and 74% of parents answered at least one legislation or health items incorrectly, respectively. Most parents reported talking to their children about legislation (56%), not using cannabis (75%) and rules around drug use (90%). Conclusions: While parents reported communicating with their children about cannabis, the majority had gaps in their knowledge. The results of this study indicate a need for effective cannabis education interventions.

Health, safety, and socioeconomic impacts of cannabis liberalization laws: An evidence and gap map. CAMPBELL SYSTEMATIC REVIEWS 2023; 19:e1362.

Abstract
Background Globally, cannabis laws and regulations are rapidly changing. Countries are increasingly permitting access to cannabis under various decriminalization, medicalization, and legalization laws. With strong economic, public health, and social justice incentives driving these domestic cannabis policy reforms, liberalization trends are bound to continue. However, despite a large and growing body of interdisciplinary research addressing the policy-relevant health, safety, and socioeconomic consequences of cannabis liberalization, there is a lack of robust primary and systematic research that comprehensively investigates the consequences of these reforms. Objectives This evidence and gap map (EGM) summarizes the empirical evidence on cannabis liberalization policies. Primary objectives were to develop a conceptual framework linking cannabis liberalization policies to relevant outcomes, descriptively summarize the empirical evidence, and identify areas of evidence concentration and gaps. Search Methods We comprehensively searched for eligible English-language empirical studies published across 23 academic databases and 11 gray literature sources through August 2020. Additions to the pool of potentially eligible studies from supplemental sources were made through November 2020. Selection Criteria The conceptual framework for this EGM draws upon a legal epidemiological perspective highlighting the causal effects of law and policy on population-level outcomes. Eligible interventions include policies that create or expand access to a legal or decriminalized supply of cannabis: comprehensive medical cannabis laws (MCLs), limited medical cannabidiol laws (CBDLs), recreational cannabis laws (RCLs), industrial hemp laws (IHLs), and decriminalization of cultivations laws (DCLs). Eligible outcomes include intermediate responses (i.e., attitudes/behaviors and markets/environments) and longer-term consequences (health, safety, and socioeconomic outcomes) of these laws. Data Collection and Analysis Both dual screening and dual data extraction were performed with third person deconfliction. Primary studies were appraised using the Maryland Scientific Methods Scale and systematic reviews were assessed using AMSTAR 2. Main Results The EGM includes 447 studies, comprising 438 primary studies and nine systematic reviews. Most research derives from the United States, with little research from other countries. By far, most cannabis liberalization research focuses on the effects of MCLs and RCLs. Studies targeting other laws-including CBDLs, IHLs, and DCLs-are relatively rare. Of the 113 distinct outcomes we documented, cannabis use was the single most frequently investigated. More than half these outcomes were addressed by three or fewer studies, highlighting substantial evidence gaps in the literature. The systematic evidence base is relatively small, comprising just seven completed reviews on cannabis use (3), opioid-related harms (3), and alcohol-related outcomes (1). Moreover, we have limited confidence in the reviews, as five were appraised as minimal quality and two as low quality. Authors’ Conclusions More primary and systematic research is needed to better understand the effects of cannabis liberalization laws on longer-term-and arguably more salient-health, safety, and socioeconomic outcomes. Since most research concerns MCLs and RCLs, there is a critical need for research on the societal impacts of industrial hemp production, medical CBD products, and decriminalized cannabis cultivation. Future research should also prioritize understanding the heterogeneous effects of these laws given differences in specific provisions and implementation across jurisdictions.

Cannabis smoking, tobacco cigarette smoking, and adenomyosis risk. Fertil Steril 2023; 119:838-846. [PMID: 36716812 PMCID: PMC10900224 DOI: 10.1016/j.fertnstert.2023.01.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 01/18/2023] [Accepted: 01/19/2023] [Indexed: 01/30/2023]
Abstract
OBJECTIVE To investigate cannabis smoking and tobacco cigarette smoking in relation to adenomyosis risk. DESIGN We used data from a case-control study of adenomyosis conducted among enrollees ages 18-59 years of an integrated health care system in Washington State. The case-control study used 2 control groups given the challenge of selecting noncases when cases are diagnosed by hysterectomy. SUBJECTS Cases (n = 386) were enrollees with incident, pathology-confirmed adenomyosis diagnosed between April 1, 2001, and March 31, 2006. The 2 control groups comprised hysterectomy controls (n = 233) with pathology-confirmed absence of adenomyosis and population controls (n = 323) with an intact uterus selected randomly from the health care system population and frequency matched to cases on age. EXPOSURE Detailed data on cannabis and tobacco cigarette smoking history were ascertained through in-person structured interviews, allowing estimation of joint-years of cannabis smoking and pack-years of tobacco cigarette smoking. MAIN OUTCOME MEASURES Odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between cannabis smoking, tobacco cigarette smoking, and adenomyosis were estimated using multivariable unconditional logistic regression. Analyses were adjusted for age, reference year, menarche age, education, and pack-years of cigarette smoking (or joint-years of cannabis smoking). RESULTS No association was observed between cannabis smoking history and adenomyosis risk. However, we did observe the suggestion of an association between ever tobacco cigarette smoking and adenomyosis risk, comparing cases to hysterectomy controls (OR, 1.3; 95% CI, 0.9-1.9) and population controls (OR, 1.2; 95% CI, 0.8-1.8). Our data suggested a 50% increased odds of adenomyosis with >15 pack-years of smoking (vs. never smoking), comparing cases to hysterectomy controls (OR, 1.5; 95% CI, 0.9-2.6; Ptrend=.135). The suggestion of a 40% increased adenomyosis odds was observed with smoking >5-15 pack-years (vs. never smoking), comparing cases to population controls (OR, 1.4; 95% CI, 0.8-2.4; Ptrend=0.136). CONCLUSION In the first study of cannabis smoking and adenomyosis risk, no association was observed. However, our data suggested an increased odds of adenomyosis with history of tobacco cigarette smoking. Further research is warranted to replicate our results given the substantial morbidity with adenomyosis and frequency of cigarette smoking and recreational and medical cannabis use.

Assessing the Impact of Recreational Cannabis Legalization on Cannabis Use Disorder and Admissions to Treatment in the United States. CURRENT ADDICTION REPORTS 2023; 10:198-209. [PMID: 37266190 PMCID: PMC10088679 DOI: 10.1007/s40429-023-00470-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/07/2023] [Indexed: 06/03/2023]
Abstract
Purpose of Review Policy implications from changes in recreational cannabis laws (RCLs) have raised public health concerns. While numerous studies have examined the impact of RCLs on cannabis use, there is less research on the risk of developing cannabis use disorder (CUD). This review summarizes the latest research on the effects of RCLs on CUD prevalence and cannabis treatment admissions. Recent Findings Nine studies were published between 2016 - 2022 that examined RCLs and CUD or treatment. Findings generally indicate an increase in CUD prevalence associated with legalization, but effects differ by age group. There was no significant association between legalization and CUD treatment admissions, and CUD admissions decreased overall during the study periods. Summary To improve policy, prevention, and treatment services, policymakers should monitor RCLs' effects on adverse public health outcomes and researchers should consider the effects on individual and community-level characteristics. We discuss methodological challenges in conducting state-level research and provide suggestions for future studies.

Impacts of recreational cannabis legalization on use and harms: A narrative review of sex/gender differences. Front Psychiatry 2023; 14:1127660. [PMID: 36970279 PMCID: PMC10036775 DOI: 10.3389/fpsyt.2023.1127660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 02/20/2023] [Indexed: 03/12/2023] Open
Abstract
Legalization of cannabis use for non-medical (recreational) purposes is changing the global cannabis landscape. As attitudes toward cannabis use become more positive and prevalence of use increases in complex ways, concerns emerge about the potential for increased cannabis-attributable harms. Understanding the who, why, and when of this likely increase in cannabis-attributable harms is thus an important public health priority. Both sex and gender contribute to variability in the use, effects, and harms of cannabis and thus sex/gender considerations are important when evaluating the impacts of cannabis legalization. The goal of this narrative review is to broadly discuss sex/gender differences in attitudes toward and prevalence of cannabis use, whether there are sex/gender differences in the impacts of cannabis legalization, and why these sex/gender differences might exist. One of our strongest conclusions is that men have always been more likely to use cannabis than women, yet the sex/gender gap in prevalence of cannabis use has narrowed over time, and this might be partly due to cannabis legalization. The existing evidence suggests that there have also been sex/gender differences in the impacts of legalization on cannabis-attributable harms such as cannabis-involved motor vehicle collisions and hospitalizations, though these results are more variable. The body of literature reviewed has focused almost exclusively on samples of cisgender research participants, and thus future research should encourage inclusion of transgender and gender-diverse participants. More consideration of sex- and gender-based analysis in research evaluating long-term impacts of cannabis legalization is a clear research priority.

Sharing pro-marijuana messaging on social media: The moderating role of legislation. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2022; 70:2318-2326. [PMID: 33522463 DOI: 10.1080/07448481.2020.1851694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 10/28/2020] [Accepted: 11/06/2020] [Indexed: 06/12/2023]
Abstract
ObjectivesThis study investigates whether recreational marijuana legislation and perceived social norms (descriptive and injunctive) affect college students' propensity to share pro-marijuana messages. We examine which referent group (close friends, typical student, parents) most influence those norms. Participants: A sample of 343 college students participated in the study. Of these students, 214 were from Washington State, where recreational marijuana is legal, and 129 were from Wyoming, where recreational marijuana is illegal. Method: Data, from an online survey, were analyzed through PROCESS analyses. Results: College students in Washington State who believed a typical peer would want them to share pro-marijuana messaging were marginally more likely to share pro-marijuana messages than their counterparts in Wyoming. However, among students who thought a typical peer would not approve of them sharing pro-marijuana messaging, the opposite pattern emerged. Conclusion: Restrictive recreational marijuana legislation does not uniformly abate related message sharing on social media.

Abstract
OBJECTIVE To provide health care providers with the best evidence on cannabis use and women's health. Areas of focus include screening, dependence, and withdrawal; communication and documentation; pregnancy (including maternal and fetal outcomes); maternal pain control; postpartum care (including second-hand smoking and parenting); and breastfeeding. TARGET POPULATION The target population includes women who are planning a pregnancy, pregnant, or breastfeeding. BENEFITS, HARMS, AND COSTS Discussing cannabis use with women who are planning a pregnancy, pregnant, or breastfeeding allows them to make informed choices about their cannabis use. Based on the limited evidence, cannabis use in pregnancy or while breastfeeding should be avoided, or reduced as much as possible if abstaining is not feasible, given the absence of safety and long-term follow up data on cannabis-exposed pregnancies and infants. EVIDENCE PubMed and Cochrane Library databases were searched for articles relevant to cannabis use during pregnancy and breastfeeding published between January 1, 2018, and February 5, 2021. The search terms were developed using the MeSH terms and keywords and their variants, including cannabis, cannabinoids, cannabidiol, CBD, THC, marijuana, edible, pregnancy, pregnant, prenatal, perinatal, postnatal, breastfeed, breastfed, lactation, nursing, fetus, fetal, neonatal, newborn, and child. In terms of publication type, all clinical trials, observational studies, reviews (including systematic reviews and meta-analyses), guidelines, and conference consensus statements were included. The main inclusion criteria were pregnant and breastfeeding women as the target population, and exposure to cannabis as the intervention of interest. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE All health care providers who care for women of reproductive age. SUMMARY STATEMENTS RECOMMENDATIONS.

Causal effects of cannabis legalization on parents, parenting, and children: A systematic review. Prev Med 2022; 156:106956.

Abstract
Medical and recreational cannabis legalization lead to increased cannabis use among adults. There is concern that legalization has negative implications for minors via effects on parents. We conducted a systematic review of studies examining legalization in the United States. Web of Science, PsycInfo, and PubMed were searched through May 2021, studies examining effects of legalization on maternal cannabis and other substance use during pregnancy and postpartum, perinatal outcomes, parental cannabis and other substance use and attitudes, parenting, and child outcomes were identified, and two independent reviewers extracted information on study designs, samples, and outcomes, and assessed classification of evidence and risk of bias. Forty-one studies met inclusion criteria; only 6 (15%) used the most causally informative study design (difference in differences). It is likely legalization increases maternal cannabis use during pregnancy and postpartum, parental cannabis use, and approval of adult cannabis use. Legalization may increase some adverse perinatal outcomes, though findings were inconsistent. It is likely legalization increases unintentional pediatric cannabis exposure. There is insufficient evidence for effects of legalization on child abuse and neglect, and there have been no studies examining effects of legalization on other aspects of parenting or on child adjustment. There is a critical lack of causally informative epidemiological studies examining effects of legalization on parenting and young children. Additional causally informative research is needed. Studies of parental cannabis use in a legal context are particularly needed. Commonsense guidelines must recognize the shifting national landscape around legalization while seeking to minimize potential harm to minors.

Abstract
AIM Cannabis use is associated with greater likelihood of psychosis. The relationship between attitudes about cannabis and use has not been examined in youth at clinical high-risk (CHR) for psychosis. Additionally, the shifting legal landscape can provide a valuable context for evaluating use and related attitudes. METHODS This study included 174 participants (44 CHR, 43 healthy control [HC] youth-parent dyads). Youth completed measures of self-reported cannabis use confirmed with a urinalysis, self-perceived risk and perceived peer attitudes. Parents reported attitudes about youth use. Legalization occurred halfway during a 5-year study in Colorado, providing an opportunity to cross-sectionally examine its role in use and attitudes. RESULTS Frequency of youth reporting cannabis use was significantly higher in CHR (69%) than control group (30%). Use in CHR group was associated with higher perceived peer approval (r = .57), increased parental permissiveness (r = .28) and lower self-perceived risk (r = -.26). Comparing samples participating pre and post-legalization, use remained stable within each group. Group differences in parental permissiveness shifted; trend toward decrease in permissiveness in CHR group (η2partial = .07) and a significant increase in HCs (η2partial = .16) were observed. Post-legalization, use in CHR group correlated with higher perceived peer approval (r = .64), lower self-perceived risk (r = -.51) and higher parental permissiveness (r = .35, trend). CONCLUSIONS Taken together, results indicate a relationship between self and peer/parental attitudes about cannabis and use in youth at CHR for psychosis. These factors are important to consider within the legalization context given the changes in parental attitudes and a stronger association between use and attitudes in this group post-legalization.

Abstract
BACKGROUND Cannabis policies are rapidly changing in the United States, yet little is known about how this has affected cannabis-associated emergency department (ED) visits. METHODS We studied trends in cannabis-associated ED visits and identified differences by visit characteristics. Cannabis-associated ED visits from 2006 to 2018 were identified from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project's (HCUP) Nationwide Emergency Department Sample (NEDS). JoinPoint analysis was used to identify trends from 2006 to 2014, prior to medical coding changes in 2015, and Z-tests were used to compare annual rate changes from 2016 to 2018. Changes in rates from 2017 to 2018 were examined by visit characteristics. RESULTS From 2006-2014, the rate of cannabis-associated ED visits increased, on average, 12.1% annually (p < 0.05), from 12.3 to 34.7 visits per 100,000 population. The rate increased 17.3% from 2016 to 2017 (p < 0.05) and 11.1% from 2017 to 2018 (p < 0.05). From 2017-2018, rates of visits increased for both males (8.7%; p < 0.05) and females (15.9%; p < 0.05). Patients 0-14 years and 25 years and older had significant rate increases from 2017 to 2018 as did the Midwest region (36.8%; p < 0.05), the Northeast (9.2%; p < 0.05), and the South (4.5%; p < 0.05). CONCLUSIONS Cannabis-associated ED visits are on the rise and subgroups are at increased risk. Some potential explanations for increases in cannabis-associated ED visits include increased availability of cannabis products, increased use, and diversity of products available in marketplaces. Strategies are needed to prevent youth initiation, limit potentially harmful use among adults, and ensure safe storage where cannabis use is legal.

Abstract
Objective This study explored the relationships between marijuana knowledge, confidence in knowledge, and information efficacy and marijuana use. Furthermore, the effects of the knowledge-related variables were examined on intention to use, resistance efficacy, and intention to vote for legalization. Participants: Undergraduate students (N = 215) were surveyed in Fall 2018. Methods: Data were collected online and analyzed through a series of regression analyses. Results: Higher knowledge was related to less use via higher perceived risk whereas higher confidence in knowledge was related to more use. Marijuana use was related to higher future intention to use, lower resistance self-efficacy, and intention to vote for legalization. Information efficacy was related to intention to vote for legalization only. Conclusions: Students with more knowledge were less likely to use marijuana, whereas students who considered themselves well-informed were more likely to use it. Future intervention efforts will benefit from counteracting students' misplaced confidence in their knowledge.

[PMID: 34509738 PMCID: PMC8713458 DOI: 10.1016/j.drugalcdep.2021.109019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 07/15/2021] [Accepted: 07/18/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND Parental cannabis use is associated with increased risks of cannabis use among offspring, yet few studies have explored the mechanisms influencing intergenerational continuity in cannabis use. To understand the mechanism by which intergenerational cannabis use is influenced, this work explores cannabis use across three generations using a family expansion of the Theory of Reasoned Action (TRA). METHODS Data come from the Young Women and Child Development Study which began when teen mothers were pregnant and followed mother-child dyads for 17 years (N = 240). Constructs include cannabis use of grandparents, mothers, and teens, and TRA constructs of behavioral and normative beliefs, intention, and behavior. Hypotheses were tested using Structural Equation Modeling. RESULTS Grandfather's cannabis use was significantly linked to mother's normative beliefs (β = .22, p = .006), but not attitudes (β = .12, p = .182). Teen mothers' attitude was associated with intention (β = .79, p < .001); intention predicted cannabis behavior (β = .61, p < .001). Teen mothers' cannabis use was predictive of adolescent's attitude (β = .21, p = .002); attitude predicted intention (β = .73, p < .001) and intention predicted behavior (β = .60, p < .001). DISCUSSION Parents play an influential role in the cannabis use behaviors of adolescents. Future work should consider interventions that target both parent and adolescents, increasing knowledge and skills related to parent-child communication, parental monitoring, and positive parental role modeling to reduce intergenerational continuity of cannabis use.

Demographic and policy-based differences in behaviors and attitudes towards driving after marijuana use: an analysis of the 2013-2017 Traffic Safety Culture Index. BMC Res Notes 2021; 14:226. [PMID: 34082823 PMCID: PMC8176701 DOI: 10.1186/s13104-021-05643-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 05/27/2021] [Indexed: 11/10/2022] Open
Abstract
OBJECTIVE Marijuana policies in the United States have become more permissive, motivating research on demographic and policy-based differences in behaviors and attitudes towards driving after marijuana use. The Traffic Safety Culture Index is an annual survey with national scope and multiple measures relevant to driving after marijuana use. We tabulated responses to questions about driving after marijuana use from the Traffic Safety Culture Index based on demographic factors, recreational and medical marijuana policies, and per-se marijuana laws. RESULTS Male, younger, lower-income, and lower-education respondents self-reported driving after marijuana use more than their demographic counterparts, more often reported such behavior to be personally acceptable, and exhibited lower support per-se laws. Drivers in states that legalized medical marijuana self-reported driving after marijuana use slightly more than drivers in states where both medical and recreational were illegal. Support for per-se laws was higher among those in states that legalized recreational marijuana and in states with per-se laws. Demographic differences in our outcomes were consistent and cohesive. On the other hand, we found no predominant pattern suggesting that those in states with liberal marijuana policies were more tolerant of driving after marijuana use.

Abstract
Six original research papers were submitted to this Special Section to address questions regarding the intergenerational transmission of risk for cannabis and other substance use. Study teams recruited youth in Iowa, Washington, Oregon, New York, and Arizona in the 1980s-1990s, assessed them into adulthood, and recruited their partners and offspring for another study. All of the studies assessed substance use in 2 or more generations. Other strengths in this section include the strong representation of fathers, the demographic diversity of the samples as a whole, and the demonstrations of varied statistical and replication approaches. The findings highlight features of parental histories of cannabis use during adolescence that are associated with their children's risk for cannabis use and factors that explain or weaken intergenerational similarities. Two groups of prevention scholars also offered commentaries on the implications of these studies for prevention and training, and collaboration. It is hoped that the Special Section will stimulate new hypotheses, replications, and communication among etiological and prevention researchers. Furthermore, the papers highlight that the familial transmission of substance use risk should be taken into account more fully in the design of prevention programs to maximize impacts for youth as well as their future offspring.

Abstract
Background: Public acceptance of cannabis continues to increase across the US, yet there has been little research on how cannabis legalization affects young children. The present study compared knowledge of cannabis and other substances among children living in states with different cannabis laws and examined whether the association between such substance knowledge and externalizing behavior varies by state cannabis regulations. Methods: Participants were from the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®) at the baseline assessment (N = 11,875, ages 9-11, collected from 2016 to 2018). Chi-square difference tests were used to compare nested models testing group differences in knowledge of substances and the association between externalizing disorder/behavior and substance knowledge as a function of state legality of cannabis use (recreational, medical, low THC/CBD, none). Results: Children living in states with more permissive cannabis laws had a greater knowledge of cannabis and reported more alcohol experimentation. In contrast, knowledge regarding alcohol, tobacco, and other illicit drugs was not greater in children from states with more permissive cannabis laws. Externalizing disorder/behavior was not significantly associated with cannabis knowledge in any group and not significantly different across groups. The association between externalizing disorder/behavior and illicit drug knowledge was significant only in states with the recreational and medical use laws but did not differ significantly across groups. Conclusion: Children living in environments with more permissive cannabis regulations have greater knowledge of cannabis, but not other substances, and report more experimentation with alcohol.

Evaluating the effect of retail marijuana legalization on parent marijuana use frequency and norms in U.S. States with retail marijuana legalization. Addict Behav 2020; 111:106564. [PMID: 32739591 DOI: 10.1016/j.addbeh.2020.106564] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 06/04/2020] [Accepted: 07/16/2020] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To examine post-retail marijuana legalization (RML) change in marijuana use frequency and pro-marijuana norms among parents. METHODS The Intergenerational Study, a longitudinal panel of parents (N = 668) and children, followed participants from 2002 to 2018, when parents were 27 and 43 years old, respectively. Three quarters of participants (74%) lived in an RML state and 142 (21%) had used marijuana in the 8 years prior to RML. Piecewise growth modelling compared pre- and post-RML slopes of use frequency and pro-marijuana norms. RESULTS Frequency of use and pro-marijuana norms increased following legalization in both RML and non-RML states, though norms rose significantly faster in RML states. Growth in use was primarily driven by new users of marijuana. There were no differences in frequency of marijuana use or pro-marijuana norms by race/ethnicity, gender, or education. CONCLUSIONS An increase in marijuana use frequency associated with RML among parents poses risk to both parents' well-being and the health of their children. A faster pace of increase in pro-marijuana norms in RML states may signal continued increases in use in the future.

Abstract
In recent years, marijuana use on U.S. college campuses reached the highest point while the perceptions of risk and social disapproval registered the lowest since the early 1980s. However, little attention has been paid to the sources of the marijuana-related messages and their relationships with marijuana knowledge and confidence in knowledge, proximate protective/risk factors. To fill this gap, a convenience sample of students (N = 249) on a campus located in a U.S. recreational marijuana legal state were surveyed to identify their marijuana information sources and explore the relationships among the sources, confidence in marijuana knowledge, and objective knowledge. Peers/media were the most important sources and they were used more than other sources. Use of peers/media sources was related to lower health knowledge and higher confidence in knowledge. Although students named parents and education/science sources as important, these were less frequently used than siblings, the sources they named as the least important. This study advanced our understanding of the various sources of marijuana information used by U.S. college students and the relationships between the information sources and confidence in knowledge and objective knowledge, two emerging risk/protective factors in the era of marijuana deregulation.

Self-reported driving after marijuana use in association with medical and recreational marijuana policies. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 92:102944.

Abstract
BACKGROUND A common concern surrounding increasingly permissive marijuana policies in the US is that they will lead to more dangerous behavior, including driving after marijuana use. Although there is considerable research on the effects of marijuana policies on behaviours, few studies have examined self-reported driving after marijuana use. In this study, we use data from the Traffic Safety Culture Index (TSCI) to model self-reported past-year driving after marijuana use in association with medical and recreational marijuana policies. METHODS We analysed individual responses to annual administrations of TSCI from years 2013-2017 using a multiple logistic regression model. Our outcome variable was self-reported past-year driving after marijuana use (at least once vs. never), and our primary explanatory variable was the respondents' state medical marijuana (MM) and recreational marijuana (RM) policy. Additional explanatory variables include policies that specify thresholds for marijuana-intoxicated driving, year, and demographic factors. RESULTS Drivers in states that legalized MM but not RM had marginally higher odds of self-reporting driving after marijuana use compared to drivers in states where both RM and MM were illegal (adjusted OR 1.29; 95% CI 0.98, 1.70; p = 0.075). However, we found little evidence that drivers in states that legalized both RM and MM had higher odds of driving after marijuana use compared to drivers in states where both RM and MM were illegal (adjusted OR 1.06; 95% CI 0.71, 1.56; p = 0.784). Per-se or THC threshold laws were associated with lower self-reported driving after marijuana use (adjusted OR 0.74; 95% CI 0.57, 0.95; p = 0.018). CONCLUSION Although we found some evidence of an association between MM legalization and self-reported driving after marijuana use, our results provide only mixed support for the hypothesis that permissive marijuana policies are associated with higher odds of self-reported driving after marijuana use.

Abstract
OBJECTIVES To review the metrics and findings of studies evaluating effects of drug decriminalisation or legal regulation on drug availability, use or related health and social harms globally. DESIGN Systematic review with narrative synthesis. DATA SOURCES We searched MEDLINE, Embase, PsycINFO, Web of Science and six additional databases for publications from 1 January 1970 through 4 October 2018. INCLUSION CRITERIA Peer-reviewed articles or published abstracts in any language with quantitative data on drug availability, use or related health and social harms collected before and after implementation of de jure drug decriminalisation or legal regulation. DATA EXTRACTION AND SYNTHESIS Two independent reviewers screened titles, abstracts and articles for inclusion. Extraction and quality appraisal (modified Downs and Black checklist) were performed by one reviewer and checked by a second, with discrepancies resolved by a third. We coded study-level outcome measures into metric groupings and categorised the estimated direction of association between the legal change and outcomes of interest. RESULTS We screened 4860 titles and 221 full-texts and included 114 articles. Most (n=104, 91.2%) were from the USA, evaluated cannabis reform (n=109, 95.6%) and focussed on legal regulation (n=96, 84.2%). 224 study outcome measures were categorised into 32 metrics, most commonly prevalence (39.5% of studies), frequency (14.0%) or perceived harmfulness (10.5%) of use of the decriminalised or regulated drug; or use of tobacco, alcohol or other drugs (12.3%). Across all substance use metrics, legal reform was most often not associated with changes in use. CONCLUSIONS Studies evaluating drug decriminalisation and legal regulation are concentrated in the USA and on cannabis legalisation. Despite the range of outcomes potentially impacted by drug law reform, extant research is narrowly focussed, with a particular emphasis on the prevalence of use. Metrics in drug law reform evaluations require improved alignment with relevant health and social outcomes.

Abstract
Driving under the influence of drugs (e.g., marijuana, prescription medications) is a major public health and safety concern. As a relatively understudied and growing problem, prevention strategies that address it are not as clear, well-tested, or evidence-based as those developed for preventing other risky behaviors such as drunk driving. Key components of a successful prevention of this harmful behavior are the efforts of practitioners working in the areas of substance abuse prevention and highway safety for whom drugged driving is likely a part, but not the sole focus, of their job. We surveyed 238 prevention professionals working in substance abuse prevention and highway safety from 46 states to understand their needs, barriers, and self-efficacy to prevent drugged driving in their communities. Most respondents reported needing training and resources to implement strategies related to drugged driving, particularly with regard to engaging youth and parents, if they are to address this problem effectively. The majority of respondents also reported low levels of self-efficacy for implementing a wide range of drugged driving prevention strategies. Our findings reveal that the professionals we need to feel prepared and efficacious to prevent drugged driving have generally low feelings of confidence in their ability to do so.

Contextual risk among adolescents receiving opioid prescriptions for acute pain in pediatric ambulatory care settings. Addict Behav 2020; 104:106314.

Abstract
Many adults with opioid use disorder (OUD) report that their first exposure to opioids was in the course of routine pain treatment in medical care settings. Adolescents receive opioid prescriptions with frequency, but are susceptible to a constellation of unique risks in the context of pain management. This empirical study presents the first cohort of adolescents recruited from ambulatory medical care within 72 h of their receipt of opioids to treat acute pain. The primary aim was to capture a time-sensitive report of the intersection of prescription opioid receipt and contextual risks for opioid misuse related to pain experience, mental health symptoms, and substance use at the adolescent and parental levels. Data were collected from 70 14-19-year-old adolescents and their accompanying parent. Results reflected that 90% of this sample of adolescents reported 2 or more risks and 35% reported 5 or more risks for future opioid misuse. Pain catastrophizing (46%) and alcohol use (40%) and were the most common adolescent-level risk factors; mother history of chronic pain (32%) and parent anxiety (21%) were the most common parent-level risk factors. Past-week parent pain intensity showed the strongest association with adolescent past-week pain intensity; neither was associated with adolescent OUD symptoms. Adolescent pain catastrophizing most reliably predicted OUD symptoms; parent pain interference was also associated. Seventy-one percent of parents reported keeping opioids at home, a relevant risk factor for future misuse. These findings illuminate the intersection between adolescent and parental risks in the context of pediatric opioid prescribing for acute pain management, and provide initial insight into potential points of prevention early in adolescent pain treatment, including avenues by which to inform and enhance prescriber decision-making regarding factors to be weighed in adolescent candidacy for opioid therapy.

Abstract
Various states have legalized marijuana for medical purposes and/or decriminalized recreational marijuana use. These changes coincide with a decrease in perceived harmfulness of the drug and an increase in its use among youth. This change is of critical concern because of the potential harmful impact of marijuana exposure on adolescents. Marijuana use has been associated with several adverse mental health outcomes, including increased incidence of addiction and comorbid substance use, suicidality, and new-onset psychosis. Negative impacts on cognition and academic performance have also been observed. As the trend toward legalization continues, the pediatric community will be called on to navigate the subsequent challenges that arise with changing policies. Pediatricians are uniquely positioned to provide innovative care and educate youth and families on the ever-evolving issues pertaining to the impact of marijuana legalization on communities. In this article, we present and analyze the most up-to-date data on the effects of legalization on adolescent marijuana use, the effects of adolescent use on mental health and cognitive outcomes, and the current interventions being recommended for use in pediatric office settings.

Abstract
Accurate estimates of substance use in the teenage years by race/ethnicity may help identify when to intervene to prevent long-term substance use disparities. We examined trends in past 30-day use of marijuana, cigarette, and alcohol among 8th, 10th, and 12th graders in Washington State, which passed a recreational marijuana law in 2012 and initiated retail marijuana sales in 2014. Data are from the 2004-2016 Washington Healthy Youth Surveys (n = 161,992). We used time series regression models to assess linear and quadratic trends in substance use for the full sample and stratified on race/ethnicity and grade level and examined relative differences in prevalence of use by race/ethnicity. In Washington, across all racial/ethnic groups, marijuana use peaked in 2012. Although there was not a significant overall change in marijuana use for the full sample across the study period, there was a statistically significant increase in use among 12th graders and a statistically significant decrease among 8th graders. Relative to Whites, Asians had a lower prevalence of marijuana use, whereas all other race/ethnicity groups had a higher prevalence of use. Prevalence of marijuana use is particularly high among American Indian/Alaska Native and Black youth and has increased most rapidly among 12th grade Hispanic/Latinx youth. There were large and statistically significant decreases in alcohol and cigarette use across the study period for the full sample, as well as for each race/ethnicity group. These findings highlight the need for continued monitoring of trends in use among these groups and potentially warrant consideration of selective interventions that specifically focus on students of color and that include developmentally-appropriate strategies relevant to each grade.

Abstract
Marijuana liberalization policies are gaining momentum in the USA, coupled with limited federal interference and growing dispensary industry. This evolving regulatory landscape underscores the importance of understanding the attitudinal/perceptual pathways from marijuana policy to marijuana use behavior, especially for adolescents and young adults. Our study uses the restricted-access National Survey on Drug Use and Health (NSDUH) 2004-2012 data and a difference-in-differences design to compare the pre-policy, post-policy changes in marijuana-related attitude/perception between adolescents and young adults from ten states that implemented medical marijuana laws during the study period and those from the remaining states. We examined four attitudinal/perception pathways that may play a role in adolescent and young adult marijuana use behavior, including (1) perceived availability of marijuana, (2) perceived acceptance of marijuana use, (3) perceived wrongfulness of recreational marijuana use, and (4) perceived harmfulness of marijuana use. We found that state implementation of medical marijuana laws between 2004 and 2012 was associated with a 4.72% point increase (95% CI 0.15, 9.28) in the probability that young adults perceived no/low health risk related to marijuana use. Medical marijuana law implementation is also associated with a 0.37% point decrease (95% CI - 0.72, - 0.03) in the probability that adolescents perceived parental acceptance of marijuana use. As more states permit medical marijuana use, marijuana-related attitude/perception need to be closely monitored, especially perceived harmfulness. The physical and psychological effects of marijuana use should be carefully investigated and clearly conveyed to the public.

Abstract
Permissive attitudes and norms about marijuana use and perceptions of low harm from use are considered risk factors for adolescent marijuana use. However, the relationship between risk and use may be reciprocal and vary across development and socializing domains. We examined the bidirectional relationships between marijuana-specific risk factors in individual, parent, peer, and community domains and adolescent marijuana use. Longitudinal data came from a sample of 2002 adolescents in 12 communities. Controlling for sociodemographic covariates and communities in which the individuals resided, autoregressive cross-lagged models examined predictive associations between the risk factors and marijuana use. After accounting for concurrent relationships between risk and use and stability in behavior over time, early adolescence and the transition to high school were particularly salient developmental time points. Specifically, higher risk in all four domains in grades 7 and 9 predicted greater use 1 year later. Moreover, youth's perception of lax community enforcement of laws regarding adolescent use at all time points predicted increases in marijuana use at the subsequent assessment, and perceived low harm from use was a risk factor that prospectively predicted more marijuana use at most of the time points. Finally, greater frequency of marijuana use predicted higher levels of risk factors at the next time point in most socializing domains throughout adolescence. Prevention programs should take into account developmental transitions, especially in early adolescence and during the transition to high school. They also should focus on the reciprocal relationships between use and risk across multiple socializing domains.

Abstract
IMPORTANCE Little is known about changes in marijuana use and cannabis use disorder (CUD) after recreational marijuana legalization (RML). OBJECTIVES To examine the associations between RML enactment and changes in marijuana use, frequent use, and CUD in the United States from 2008 to 2016. DESIGN, SETTING, AND PARTICIPANTS This survey study used repeated cross-sectional survey data from the National Survey on Drug Use and Health (2008-2016) conducted in the United States among participants in the age groups of 12 to 17, 18 to 25, and 26 years or older. INTERVENTIONS Multilevel logistic regression models were fit to obtain estimates of before-vs-after changes in marijuana use among respondents in states enacting RML compared to changes in other states. MAIN OUTCOMES AND MEASURES Self-reported past-month marijuana use, past-month frequent marijuana use, past-month frequent use among past-month users, past-year CUD, and past-year CUD among past-year users. RESULTS The study included 505 796 respondents consisting of 51.51% females and 77.24% participants 26 years or older. Among the total, 65.43% were white, 11.90% black, 15.36% Hispanic, and 7.31% of other race/ethnicity. Among respondents aged 12 to 17 years, past-year CUD increased from 2.18% to 2.72% after RML enactment, a 25% higher increase than that for the same age group in states that did not enact RML (odds ratio [OR], 1.25; 95% CI, 1.01-1.55). Among past-year marijuana users in this age group, CUD increased from 22.80% to 27.20% (OR, 1.27; 95% CI, 1.01-1.59). Unmeasured confounders would need to be more prevalent in RML states and increase the risk of cannabis use by 1.08 to 1.11 times to explain observed results, indicating results that are sensitive to omitted variables. No associations were found among the respondents aged 18 to 25 years. Among respondents 26 years or older, past-month marijuana use after RML enactment increased from 5.65% to 7.10% (OR, 1.28; 95% CI, 1.16-1.40), past-month frequent use from 2.13% to 2.62% (OR, 1.24; 95% CI, 1.08-1.41), and past-year CUD from 0.90% to 1.23% (OR, 1.36; 95% CI, 1.08-1.71); these results were more robust to unmeasured confounding. Among marijuana users in this age group, past-month frequent marijuana use and past-year CUD did not increase after RML enactment. CONCLUSIONS AND RELEVANCE This study's findings suggest that although marijuana legalization advanced social justice goals, the small post-RML increase in risk for CUD among respondents aged 12 to 17 years and increased frequent use and CUD among adults 26 years or older in this study are a potential public health concern. To undertake prevention efforts, further studies are warranted to assess how these increases occur and to identify subpopulations that may be especially vulnerable.

Abstract
Most states in the United States have legalized medical and/or recreational cannabis in response to public demand. Trends in states adopting such legislation demonstrate an increasing prevalence of cannabis use coincident to decreasing perceptions of risk of harm from cannabis products. When providing anticipatory guidance, pediatricians should be prepared to address childhood unintentional ingestion management and prevention, adolescent problem use, and cannabis as an alternative therapy for seizure disorders and other conditions.

Abstract
OBJECTIVE Parents in Washington State face new challenges related to the non-medical marijuana legislation that was passed in 2012. We asked parent focus group participants about changes they have observed in their environment, how their children are exposed to marijuana, and how this exposure might affect youth marijuana use. METHOD We conducted 6 focus groups with parents of youth ages 8 to 15 (N = 54). Parents were recruited from the Seattle Social Development Project, a multi-ethnic, longitudinal panel study that originated in Seattle in 1985. Thematic content analysis was used to analyze qualitative data. RESULTS Parents agreed that they did not want their children using marijuana, and were concerned that their children were exposed to marijuana more often and in many different contexts. Parents said they now need to monitor their children's environment more carefully, especially the other adults that spend time around their children. Edible marijuana products were particularly concerning for parents, as they offer a new set of challenges for parents in monitoring their children's exposure to and use of marijuana. Parents were concerned that marijuana exposure would increase risk of marijuana use in adolescents. CONCLUSIONS Parents' experiences in Washington State provide valuable lessons for social work practitioners, policymakers and those developing preventive interventions. Prevention efforts and public health messaging should begin before legalization takes effect to support parents in preparing for changes in their social and physical environments, and should seek to incorporate parenting strategies to monitor and intervene when children are exposed to marijuana.

The Role of Life Events/Contextual Factors and Cannabis Use in Patterns of Other Drug Use Among Young Adult Cannabis Users in Los Angeles: A Qualitative Inquiry. JOURNAL OF DRUG ISSUES 2020; 50:157-172.

Abstract
This analysis examined the role of impactful life events/stressful contextual factors and cannabis use in the patterns of illicit drug use. It utilized semi-structured qualitative interviews with 40 young adult medical cannabis patients and 22 non-patient users collected in Los Angeles during 2014-2015. Three patterns of illicit drug use emerged based on participants' narratives: regular/problematic, recreational/occasional, and never users. Among regular/problematic users, a common theme was the lasting impact of traumatic life events or stressful contextual factors on transition to and away from problematic drug use, and using cannabis to cope with negative after effects of drug use. In contrast, most recreational/occasional and never users, who reported impactful life events or stressful contextual factors, used cannabis to cope with those experiences. Family history of addiction and acceptance of cannabis use within a family as protective factors against illicit drug use among some recreational/occasional and never users was an unexpected finding.

Abstract
We examined alcohol, tobacco, and marijuana (ATM) use onset across early to late adolescence in a sample of fathers and their offspring. We tested a theory of developmental congruence in polysubstance use, or the extent to which fathers' ATM use onset in early adolescence increased risk for earlier ATM onset by their offspring. Average rates of adolescent ATM use onset were also compared across generations, which may reflect intergenerational discontinuity and secular trends. Children (n = 223, 44% boys) and their fathers (n = 113; originally recruited as boys at neighborhood risk for delinquency) contributed repeated prospective self-reports of their ATM use across adolescence (as late as age 18 years). Mothers' ATM use (retrospective) through age 18 years was available for 205 children. Data were analyzed using discrete-time survival mixture analysis. Compared with their fathers, boys and girls showed later onset for tobacco use, and girls showed later onset alcohol use. Developmental congruence was partially supported: Children showed earlier ATM use onset if their fathers were assigned to the early adolescent polysubstance use onset class, compared to the late-adolescent predominantly alcohol and tobacco onset class; mothers' ATM use in adolescence attenuated this effect. Consistent with national secular trends, rates of adolescent onset tobacco and alcohol use declined across generations, whereas marijuana use onset did not. However, there was intergenerational transmission of risk for early polysubstance use onset. Prevention that delays early substance use may have early life span effects as well as transgenerational implications. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Abstract
Diverse patterns of life-course marijuana use may have differential health impacts for the children of users. Data are drawn from an intergenerational study of 426 families that included a parent, their oldest biological child, and (where appropriate) another caregiver who were interviewed 10 times from 2002 to 2018; the current study used data from 380 families in waves 6-10. Analyses linked parent marijuana use trajectories estimated in a previous publication (Epstein et al., 2015) to child marijuana, alcohol, and nicotine use; promarijuana norms; internalizing; externalizing; attention problems; and grades using multilevel modeling among children ages 6 to 21. Four trajectories had been found in the previous study: nonuser, chronic, adolescent-limited, and late-onset. Results indicate that children of parents in the groups that initiated marijuana use in adolescence (chronic and adolescent-limited) were most likely to use substances. Children of parents in the late-onset group, where parents initiated use in young adulthood, were not at increased risk for substance use but were more likely to have attention problems and lower grades. Results held when parent current marijuana use was added to the models. Implications of this work highlight the importance of considering both current use and use history in intergenerational transmission of marijuana use, and the need to address parent use history in family based prevention. Prevention of adolescent marijuana use remains a priority. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Using wastewater-based analysis to monitor the effects of legalized retail sales on cannabis consumption in Washington State, USA. Addiction 2019; 114:1582-1590. [PMID: 31211480 PMCID: PMC6814135 DOI: 10.1111/add.14641] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 01/23/2019] [Accepted: 04/22/2019] [Indexed: 11/29/2022]
Abstract
AIMS To perform a wastewater-based analysis to explore the impact of newly legalized retail cannabis sales on its use and to determine if this approach could estimate the size of the legal market place, which began 1 August 2014 in the study area. DESIGN Laboratory study of raw wastewater samples collected and analyzed over the 3-year period from 2014 to 2016. SETTING AND PARTICIPANTS Samples obtained from the two wastewater treatment plants that serviced a municipality of 200 000 people in the state of Washington, USA. MEASUREMENTS Quantitative analysis of 24-hour composite influent samples for the metabolite of the active ingredient in cannabis, 11-nor-9-Carboxy-Δ9-tetrahydrocannabinol (THC-COOH) were performed by liquid chromatography coupled to mass spectrometry. FINDINGS Wastewater estimates for THC-COOH increased by 9% per quarter, suggesting a doubling in cannabis consumption from 1 December 2013 to 31 December 2016. State-sold THC increased at nearly 70% per quarter, while stores operated from 1 August 2014 to 31 December 2016. Estimating the proportion of the total cannabis market supplied by state-regulated cannabis from these data is not currently achievable. CONCLUSION A wastewater-based measure of cannabis consumption suggests a significant increase in consumption in Washington, USA following legalization, and that legal sales appear to have displaced a large portion of the illicit market.

Parental views on state cannabis laws and marijuana use for their medically vulnerable children. Drug Alcohol Depend 2019; 199:59-67. [PMID: 30999251 DOI: 10.1016/j.drugalcdep.2018.12.027] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 11/15/2018] [Accepted: 12/01/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Given a rapidly changing policy landscape, we sought to characterize the effects of state marijuana laws on parents' views of marijuana use by their teenage children. METHODS Data are from 595 respondents to a nationally administered, web-based survey of parents of adolescents (ages 13-18 years) with any of three chronic conditions (type 1 diabetes, rheumatic disease, attention-deficit/hyperactivity disorder). Multivariate ordinal logistic regression was used to model the effects of parents' reports of state cannabis laws on their views toward marijuana use by their child. RESULTS While 89.9% said any marijuana use was risky for their child, 27.9% would approve of its use if prescribed as medicine. Parents reporting marijuana decriminalization (11.1%) were more amenable to teenage use, less concerned about how marijuana might impact their child's condition, more accepting of the safety of marijuana as medicine, and approved its use with a prescription. Parents reporting legal medical (35.6%) or recreational (5.7%) use were more likely to report that their child has tried or used marijuana regularly. Parents reporting legal recreational use were less likely to agree that marijuana has medical benefits for their child. CONCLUSIONS Among parents of medically vulnerable children, perceiving state marijuana policies as more permissive is strongly associated with lower perceived riskiness of marijuana use for their children. State marijuana policies are changing with implications for how parents of medically vulnerable youth view and potentially govern marijuana use by their medically vulnerable children.

Abstract
OBJECTIVES To assess, before legalization in Canada, whether parental cannabis use is associated with initiation of use in adolescent offspring or with use in young-adult offspring. STUDY DESIGN Data were available in 2 longitudinal studies in Montréal, Canada. In AdoQuest, 1048 parents with children in grade 6 reported past-year cannabis use. Cannabis initiation among offspring was measured in grade 7, 9, and/or 11. In the Nicotine Dependence in Teens study, cannabis use data were available for 584 participants (mean age 24 years) and their parents (ie, 542 offspring-mother pairs, 438 offspring-father pairs). The association between parental and offspring cannabis use was estimated using multivariable logistic regression in both studies. RESULTS In AdoQuest, grade 6 never-users were 1.8 times more likely to initiate cannabis during high school if their parents reported past-year use. In the Nicotine Dependence in Teens study, the aORs (95% CI) for past-year cannabis use among adult offspring were not different for "mother uses cannabis" (2.8 [1.4-5.8]) or "father uses cannabis" (2.1 [1.2-3.8]). Participants with 1 or 2 cannabis-using parents were 1.7 and 7.1 times more likely to use cannabis, respectively, than participants with non-using parents. CONCLUSIONS To enable informed decision-making about their own cannabis use, parents need to be aware that children of cannabis users are more likely to use cannabis in adolescence and young adulthood.

Abstract
OBJECTIVES This study examined marijuana-related parenting attitudes, behaviors, and challenges in the context of nonmedical marijuana legalization in Washington State. METHOD Qualitative data were collected via 6 focus groups with a total of 54 parents of preteen and teenage children, following the opening of the first marijuana retail store in Seattle in 2014. A structured interview protocol was used to ask parents about their marijuana-related parenting behaviors and about information, skills, or strategies that parents might find helpful while raising children in a state where nonmedical marijuana use is legal for adults. Transcripts were analyzed using thematic content analysis with NVivo software. RESULTS Findings indicate that most parents talked to their children about marijuana, communicating rules and information about the effects of the drug. Although most parents felt that marijuana use by underage youth was not acceptable, many recognized that it was something teens would likely experiment with. Most parents set guidelines about marijuana in their households, but several faced challenges monitoring their children's behavior (e.g., use of edibles), imposing consequences when children used marijuana, reconciling societal and personal norms, and deciding whether or not to disclose their own use. Parents expressed that they would benefit from learning strategies to deal with these challenges, including factual information and parenting skills, through programs offered in schools or community settings. CONCLUSIONS Results have implications for future research that seeks to inform prevention program development and shape policies attuned to the needs of parents.

Parents as interventionists: Addressing adolescent substance use. J Subst Abuse Treat 2019; 99:124-133.

Abstract
Much research and attention has focused on addressing the extremes of the adolescent substance use spectrum: either the prevention of substance use prior to its onset or the treatment of those with a substance use disorder (SUD). Little research has looked at adolescents who fall mid-continuum. Adolescents who use substances in this mild-to-moderate range may be efficiently and cost-effectively treated using brief interventions based on cognitive-behavioral (CB) and motivational interviewing (MI) strategies. Accessibility and feasibility of providing interventions may also be enhanced by training parents in application of CB and MI principles. An innovative home-based brief intervention for parents whose children engaged in mild to moderate drug abuse was developed and evaluated using a quasi-experimental design. Participants were parents and their adolescent child from the 7-county metro area of Minneapolis-St. Paul, Minnesota. Decreased substance use and increased family cohesion were the predicted outcomes of the Home Base intervention. Results suggest decreased adolescent marijuana use frequency, decreased alcohol use disorder symptomology, and increased parental happiness with their adolescent child. Alcohol and tobacco use frequency were statistically unchanged. Baseline levels of drug use severity moderated the relation between intervention and outcomes. These findings support the potential utility of this approach and also indicate the need to further develop accessible and efficient interventions for mild to moderate SUD.

Maternal Cannabis Use During a Child's Lifetime Associated With Earlier Initiation. Am J Prev Med 2018; 55:592-602.

Abstract
INTRODUCTION Earlier cannabis initiation is associated with more severe neuropsychiatric and social consequences. The authors investigated whether mothers' cannabis use is associated with earlier cannabis initiation by their children. METHODS Mother and child data were from the National Longitudinal Survey of Youth 1979 (1980-1998 waves) and Child and Young Adults (1988-2014 waves) cohorts, respectively. Cox proportional hazard models assessed the effect of maternal cannabis use prior to a child's adolescence on the child's risk of subsequent cannabis initiation. Models were stratified by race and child's age category (6-16, 17-24, ≥25 years). Adjusted analyses controlled for sociodemographic variables. Analyses were conducted in 2017. RESULTS Median age of cannabis initiation for children of maternal ever users was age 16years compared with age 18years among children of maternal never users. Children of 1-year and multiple-year users were at increased risk of cannabis initiation between ages 6 and 16years (hazard ratio=1.38, p<0.001, and hazard ratio = 1.45, p<0.001, respectively). Effects were slightly stronger among non-Hispanic non-black children. CONCLUSIONS As cannabis legalization expands across the U.S., adult use may become increasingly normative. This study indicates that maternal cannabis use may be a risk factor for early initiation among their offspring. Preventive interventions should consider strategies to delay initiation among children of cannabis users.

Abstract
Despite being a significant public health concern, the role of opioid prescriptions in potentiating risk of opioid misuse in the context of pediatric pain has been under-investigated. To address this gap, the present review identifies theory-based hypotheses about these associations, reviews the extant literature on opioid prescriptions that supports these hypotheses, and provides routes for future empirical studies. A multi-level model of mechanisms through which opioid prescriptions may impact pain and other negative outcomes in youth, including risk for opioid misuse and related problems, is proposed with particular attention paid to the role that psychologists can play in informing policies and developing preventative interventions in healthcare settings.

Abstract
OBJECTIVE Vasoactive substances, including marijuana, are known precipitating factors of reversible cerebral vasoconstriction syndrome (RCVS). Our objective was to describe the demographics, suspected etiology, and outcomes of RCVS patients, with specific interest in examining the subset of patients who used marijuana prior to the onset of RCVS. METHODS We identified and described consecutive RCVS cases treated at a regional, high-volume Comprehensive Stroke Center in Colorado (2012-2015). Univariate analyses were performed to examine the associations between the characteristics and outcomes (stroke and discharge disposition) of the RCVS patients by precipitating factors. We compared patients who used marijuana to those who did not and patients who used marijuana to patients who used vasoactive substances aside from marijuana. RESULTS Forty patients had RCVS. Sixteen (40%) cases were deemed idiopathic and 24 (60%) were secondary to a suspected trigger. Vasoactive substances were the most common suspected trigger (n = 18/24, 75%), 6 (33%) of which were marijuana. Approximately 80% of patients experienced an intracranial hemorrhage, 20% had an ischemic stroke, and yet 78% were discharged home. Patients with RCVS secondary to marijuana were more often male (p = 0.05) and younger (p = 0.02) compared to those who did not use marijuana; no differences were observed in the outcomes. These findings were consistent when examining marijuana versus other vasoactive substances. CONCLUSION This study suggests there are demographic differences between patients with RCVS triggered by marijuana compared to the typical RCVS patient. As more states legalize marijuana, medical conditions such as RCVS and their association with marijuana warrants further study and awareness.

Abstract
Despite strong evidence that family programs are effective in preventing adolescent substance use, recruiting parents to participate in such programs remains a persistent challenge. This study explored the feasibility of using Facebook to recruit parents of middle school students to a self-directed family program to prevent adolescent drug use. The study used paid Facebook ads aiming to recruit 100 parents in Washington and Colorado using marijuana- or parenting-focused messages. All ad-recruited parents were also invited to refer others in order to compare Facebook recruitment to web-based respondent-driven sampling. Despite offering a $15 incentive for each successfully referred participant, the majority of the screened (70.4%) and eligible (65.1%) parents were recruited through Facebook ads. Yet, eligibility and consent rates were significantly higher among referred (76.6 and 57.3%, respectively) than Facebook-recruited parents (60.0 and 36.6%, respectively). Click-through rates on Facebook were higher for marijuana-focused than parenting-focused ads (0.72 and 0.65%, respectively). The final sample (54% Facebook-recruited) consisted of 103 demographically homogeneous parents (female, educated, non-Hispanic White, and mostly from Washington). Although Facebook was an effective and efficient method to recruit parents to a study with equal to better cost-effectiveness than traditional recruitment strategies, the promise of social media to reach a diverse population was not realized. Additional approaches to Facebook recruitment are needed to reach diverse samples in real-world settings and increase public health impact of family programs.

Abstract
INTRODUCTION Cannabis use has become a more normative, socially-acceptable behavior in the United States, despite research indicating that frequent use may become problematic for some individuals. Emerging adulthood, a time of identity development, is the most common time for cannabis use. Cannabis self-concept, or one's identification with cannabis as part of their personality or identity, is one factor that may influence use behavior. This study extends previous research that reported a link between self-concept, motivational factors, and normative beliefs by evaluating relationships between cannabis self-concept, motives for use, motivation to change, perceived descriptive norms, as well as cannabis-related outcomes (use, using alone, and cannabis-related problems). METHODS Emerging adults who used cannabis in the previous month (n=345, 53.9% male, mean age 21.0, 67.5% Non-Latino White) were recruited from a community sample for a health behaviors study. Participants were assessed for explicit cannabis self-concept, frequency of use, problems associated with use, motives for use, motivation to change, and normative beliefs about others' use. RESULTS Participants reported using cannabis on an average of 17.9 (SD=11.1) days of the previous month. Correlational analyses revealed that cannabis self-concept was positively associated with frequency of use, use-related problems, several motives for use, descriptive norms, and with using cannabis alone. Multivariate analyses revealed that rates of use, problems, and social and enhancement motives were independently and positively associated (p<0.05) with cannabis self-concept, while self-concept was negatively associated with desire to reduce cannabis use. CONCLUSIONS Cannabis self-concept may be a marker for more problematic patterns of use.

Abstract
OBJECTIVE As legalization of nonmedical retail marijuana increases, states are implementing public health campaigns designed to prevent increases in youth marijuana use. This study investigated which types of marijuana-related messages were rated most highly by parents and their teens and whether these preferences differed by age and marijuana use. METHOD Nine marijuana-focused messages were developed as potential radio, newspaper, or television announcements. The messages fell into four categories: information about the law, general advice/conversation starters, consequences of marijuana use/positive alternatives, and information on potential harmful effects of teen marijuana use. The messages were presented through an online survey to 282 parent (84% female) and 283 teen (54% female) participants in an ongoing study in Washington State. RESULTS Both parents and youth rated messages containing information about the law higher than other types of messages. Messages about potential harms of marijuana use were rated lower than other messages by both generations. Parents who had used marijuana within the past year (n = 80) rated consequence/positive alternative messages lower than parent nonusers (n = 199). Youth marijuana users (n = 77) and nonusers (n = 202) both rated messages containing information about the law higher than other types of messages. Youth users and nonusers were less likely than parents to believe messages on the harmful effects of marijuana. CONCLUSIONS The high ratings for messages based on information about the marijuana law highlight the need for informational health campaigns to be established as a first step in the marijuana legalization process.

Abstract
State-level marijuana liberalization policies have been evolving for the past five decades, and yet the overall scientific evidence of the impact of these policies is widely believed to be inconclusive. In this review we summarize some of the key limitations of the studies evaluating the effects of decriminalization and medical marijuana laws on marijuana use, highlighting their inconsistencies in terms of the heterogeneity of policies, the timing of the evaluations, and the measures of use being considered. We suggest that the heterogeneity in the responsiveness of different populations to particular laws is important for interpreting the mixed findings from the literature, and we highlight the limitations of the existing literature in providing clear insights into the probable effects of marijuana legalization.
