Longitudinal associations between negative urgency, symptoms of depression, cannabis and alcohol use in veterans

Impulsivity traits moderate the longitudinal association between mental health and hazardous cannabis use in emerging adults

INTRODUCTION

The aim of this study was to examine longitudinal changes in past-month cannabis use and hazardous cannabis use over 1 year in emerging adults and to examine the prospective associations between changes in depression, anxiety, stress and hazardous cannabis use, using age, sex and impulsivity as potential moderators.

METHODS

Participants were 2762 college students (aged 18-25) who were surveyed three times over the course of a year (T1: September-November 2021; T2: March-May 2022; and T3: September-November 2022). Structural equation modelling and semi-parametric mixed-effects repeated measures models were used to examine the prospective associations between depression, anxiety, stress and hazardous cannabis use, moderated by time-variant (impulsivity trait and age) and time-invariant (sex at birth) variables.

RESULTS

The prevalence of past-month cannabis use was 11.5% at T1, 3.5% at T2 and 9.1% at T3. Autoregressive effects suggested that participants with elevated symptoms of depression, anxiety and stress at T2 tended to inform on similar impairment at T3. Cross-lagged relationships were found for anxiety at T2 and hazardous cannabis use at T3, and for hazardous cannabis use at T2 and stress at T3. Increases in emotional variables were indirectly associated with a higher risk of hazardous cannabis use through impulsivity traits.

DISCUSSION AND CONCLUSIONS

Cannabis users reported more problems in the face of worsened mental health and negative/positive urgency. Effective interventions should be framed under a transdiagnostic approach that targets emotional regulation.

Internalizing symptoms, negative urgency, and coping motives: Potential pathways to alcohol consequences

OBJECTIVE

Building upon prior research, the present study tested coping motives as a mediator of relations between both negative urgency and internalizing symptoms (depression, anxiety, and stress), and alcohol-related consequences using longitudinal data. We also tested negative urgency as a moderator of prospective relations between specific internalizing symptoms and alcohol-related consequences.

METHOD

The study utilized data from a longitudinal study of young adults (N = 448; Mage = 22.27, SD = 1.25). Participants (56.5% male) were evaluated at baseline and at 12-month and 24-month follow-ups. Mood, impulsivity, coping motives, and alcohol consequences were assessed at baseline, and motives and consequences were assessed at follow-ups.

RESULTS

Prospective indirect effects of internalizing symptoms and negative urgency on alcohol consequences through coping motives were not observed. However, cross-sectional post hoc analyses indicated that higher levels of internalizing and negative urgency were indirectly associated with greater alcohol consequences through coping motives, with similar patterns observed for depression, anxiety, and stress. Although support was found for mediated effects in the cross-sectional model, no evidence was found for negative urgency moderating the impact of internalizing, stress, anxiety, or depression on alcohol consequences in either cross-sectional or longitudinal models.

CONCLUSION

Findings provide cross-sectional but not longitudinal support for coping motives as a potential mechanism through which a broad range of internalizing symptoms are associated with alcohol consequences. Findings did not support interactions between negative urgency and internalizing symptoms. The results highlight the need for further exploration of mediated effects using ecological momentary assessments. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

The association between cannabis and depression: an updated Systematic Review and Meta-analysis

BACKGROUND

Cannabis is one of the most commonly used drugs globally, although its legal status varies across regions. Public support for its decriminalization has increased, but gaps in our understanding of the health consequences of cannabis use remain, particularly related to its impact on mental health. This article provides an updated systematic review and meta-analysis (previous being Lev-Ran et al., ) looking at the relationship between cannabis and depression.

METHODS

Literature available before March 2023 was screened for longitudinal studies that included cannabis use and depression. Cross-sectional studies and those only looking at special populations were excluded. Studies must have also controlled for depression at baseline to allow for investigation of a temporal relationship. Extracted data included cannabis measures, depression outcomes, adjusted odds ratios, and study settings. Meta-analysis employed a random effects model with multilevel meta-regression for effect size moderators.

RESULTS

The search yielded 1,599 titles from various databases, resulting in 22 studies for meta-analysis, including 14 from Lev-Ran et al. Eleven studies were US-based, with participants mostly under 18. Meta-analysis showed a higher risk of depression among cannabis users (OR: 1.29, 95% CI: 1.13-1.46). Risk of bias assessment showed medium risk across studies with exposure measurement being a key bias area. The funnel plot and Egger's Sandwich test did not suggest publication bias.

CONCLUSIONS

This study underscores the association between cannabis use and depression but also emphasizes the need for further research, especially in understanding usage patterns, heavy use definitions, and long-term effects on depression risk amidst changing cannabis trends.

Anhedonia and impulsivity in college alcohol use: A path analysis

OBJECTIVE

Alcohol use is a substantial problem among college students and has several negative consequences. The current study examined the associations between anhedonia and alcohol use and related problems via impulsive behavior (e.g., negative urgency, sensation seeking). We parsed anhedonia into four specific facets: consummatory, anticipatory, recreational, and social anhedonia.

PARTICIPANTS

Six hundred and forty college students aged 18-25 were included in the final analysis.

METHOD

Data were collected via Amazon Mechanical Turk. Self-report inventories assessing for anhedonia, alcohol use, impulsive behavior, and depressed mood were utilized.

RESULTS

Recreational consummatory anhedonia was negatively associated with alcohol use and alcohol-related problems through negative urgency. Recreational consummatory anhedonia also had significant negative associations with alcohol consumption via sensation seeking. Further, social anticipatory anhedonia was positively associated with alcohol use and related problems via negative urgency.

CONCLUSIONS

This study highlights important associations between anhedonia, impulsivity, and alcohol use and related problems.

Genome-wide DNA methylation analysis of cannabis use disorder in a veteran cohort enriched for posttraumatic stress disorder

Cannabis use has been increasing over the past decade, not only in the general US population, but particularly among military veterans. With this rise in use has come a concomitant increase in cannabis use disorder (CUD) among veterans. Here, we performed an epigenome-wide association study for lifetime CUD in an Iraq/Afghanistan era veteran cohort enriched for posttraumatic stress disorder (PTSD) comprising 2,310 total subjects (1,109 non-Hispanic black and 1,201 non-Hispanic white). We also investigated CUD interactions with current PTSD status and examined potential indirect effects of DNA methylation (DNAm) on the relationship between CUD and psychiatric diagnoses. Four CpGs were associated with lifetime CUD, even after controlling for the effects of current smoking (AHRR cg05575921, LINC00299 cg23079012, VWA7 cg22112841, and FAM70A cg08760398). Importantly, cg05575921, a CpG strongly linked to smoking, remained associated with lifetime CUD even when restricting the analysis to veterans who reported never smoking cigarettes. Moreover, CUD interacted with current PTSD to affect cg05575921 and cg23079012 such that those with both CUD and PTSD displayed significantly lower DNAm compared to the other groups. Finally, we provide preliminary evidence that AHRR cg05575921 helps explain the association between CUD and any psychiatric diagnoses, specifically mood disorders.

Mental and Physical Health Conditions Among U.S. Veterans with Cannabis Use and Cannabis Use Disorders

Purpose of Review

Veterans are a large population that is disproportionately affected by various physical and mental health conditions. The primary aim of this review is to provide a concise overview of recent literature on the prevalence of cannabis use and cannabis use disorder (CUD) among US Veterans, and associations with mental and physical health conditions. We also addressed gaps in the literature by investigating associations between CUD and mental and physical health conditions in 2019 data from the Veterans Health Administration (VHA; N=5,657,277).

Recent Findings

In total, 25 studies were reviewed. In 2019, the prevalence of Veteran cannabis use ranged from 11.9%-18.7%. Cannabis use and CUD were associated with bipolar disorders, psychotic disorders, suicidality, pain conditions, and other substance use, but less consistently associated with depressive disorders, anxiety disorders, and posttraumatic stress disorder. Analyses of 2019 VHA data indicated that CUD was strongly associated with a broad array of physical and mental health conditions and mortality.

Summary

Cannabis use and CUD are prevalent and highly comorbid with other conditions among US Veterans. Harm reduction methods tailored to these populations are needed.

Should Marijuana Be Legalized: A Scoping Review of Associations of Marijuana and Depression

People with addiction to marijuana and those who have ever consumed marijuana at any time during their life suffer from depression at some point in their life. Depression has been associated with substance use as both a trigger and repercussion. A total of 3663 articles were analyzed, and 26 articles were collectively selected for this study. Consuming marijuana was linked to the development of depression in the majority of individuals. Marijuana consumption and its repercussions have both been connected to negative effects on the body, such as respiratory disorders and even psychological disorders, including stress and depressive disorders. Studies potentially point to a complicated causal relationship between marijuana consumption and depressive disorder, stating that early depressive symptoms enable marijuana usage, which then reduces depression. A research article clearly states that consuming marijuana can be helpful in elevating mood and anxiolytic initially, but it is subsequently followed by a rise in depressive symptoms, which manifest as mental distress and frustration. Discussions with patients about the extent of their marijuana consumption, techniques for reducing the use, and the impact of marijuana on depression may be beneficial in medical facilities where depressive disorder is treated. This research paper highlights the importance of understanding depression and the use of marijuana for temporary relief from depressive symptoms and its long-term consequences on mental health.

Prospective Associations Between Anxiety Sensitivity, Distress Intolerance, Depressive Symptoms, and Indices of Alcohol and Cannabis Use Among Veterans

OBJECTIVE

There is substantial evidence linking anxiety sensitivity and distress intolerance to depressive symptoms, and further evidence linking depressive symptoms to alcohol and cannabis use. However, the prospective indirect associations of anxiety sensitivity and distress intolerance with alcohol and cannabis use through depressive symptoms remain uncertain. Thus, the current study examined whether depressive symptoms mediated the associations between anxiety sensitivity and distress intolerance with alcohol and cannabis use frequency, quantity, and problems in a longitudinal sample of veterans.

METHOD

Participants (N = 361; 93% male; 80% White) were military veterans with lifetime cannabis use recruited from a Veterans Health Administration in the Northeastern United States. Eligible veterans completed three semi-annual assessments. Prospective mediation models were used to test for the effects of baseline anxiety sensitivity and distress intolerance on alcohol and cannabis use quantity, frequency and problems at 12 months via depressive symptoms at 6 months.

RESULTS

Baseline anxiety sensitivity was positively associated with 12-month alcohol problems. Baseline distress intolerance was positively associated with 12-month cannabis use frequency and quantity. Baseline anxiety sensitivity and distress intolerance significantly predicted increased alcohol problems and cannabis use frequency at 12 months through depressive symptoms at 6 months. There were no significant indirect effects of anxiety sensitivity and distress intolerance on alcohol use frequency or quantity, cannabis use quantity, or cannabis problems.

CONCLUSIONS

Anxiety sensitivity and distress intolerance share a common pathway to alcohol problems and cannabis use frequency through depressive symptoms. Interventions focused on modulating negative affectivity may reduce cannabis use frequency and alcohol problems.

The relationship between anxious-depressive symptoms and harmful cannabis use: Multiple mediation models via rumination, negative urgency, protective behavioral strategies and refusal self-efficacy

BACKGROUND

Distressful and negative affective states can be associated with limited self-regulation capacities, while emotion regulation processes (e.g., rumination, negative urgency) might contribute to further depletion of self-control capacities which in turn can lead to diminished control over cannabis use.

AIMS

The mediating functions of rumination (i.e., brooding and reflection), negative urgency (NU) and constructs of cannabis use regulation (i.e., cannabis protective behavioral strategies [CPBS] and cannabis refusal self-efficacy [CRSE]) were examined on the associations between anxious-depressive symptoms and cannabis use outcomes (i.e., frequency, harmful use).

METHODS

The cross-sectional study used a sample of cannabis users showing signs of harmful consumption (N = 750; Males: 70.13% [N = 526]; Age: M = 29.11 [SD = 7.45]). Standardized questionnaires measured anxious-depressive symptoms, rumination, NU, CRSE, CPBS, frequency of cannabis use and harmful cannabis use. A linear regression-based, double-mediation model was performed.

RESULTS

Five significant indirect effects were demonstrated in the mediation model. Single-mediation effects were shown between anxious-depressive symptoms and harmful cannabis use via CRSE and via CPBS. Double-mediation effects were presented between anxious-depressive symptoms and harmful cannabis use via reflection and CPBS, via reflection and CRSE, and via NU and CRSE.

CONCLUSIONS

Emotion and cannabis use regulation pathways explained the associations between anxious-depressive symptoms and harmful cannabis use. The mediation model provided new details on how anxious-depressive symptoms, rumination and NU might lead to harmful cannabis use via regulation of cannabis use. Limited self-regulation capacities and similarities between emotion and cannabis use regulation processes might explain the identified indirect effects.

Cannabis induced psychosis: a systematic review on the role of genetic polymorphisms

OBJECTIVE

Cannabis sativa is a recreational drug commonly consumed in Europe and is getting popularity for both recreational and therapeutic use. In some individuals, the use of cannabis leads to psychotic disorders. This systematic review summarizes the current evidence linking genetic polymorphisms and inter-individual susceptibility to psychosis induced by cannabis.

METHOD

Studies published from 2005 to 2020 were identified through Medline using PubMed, Web of Science and Scopus database and searches were conducted according to PRISMA guidelines. Initial search was performed with terms: "cannabis induced psychosis" AND "genetics".

RESULTS

From the initial group of 108 papers, 18 studies met our inclusion criteria. Many of the findings revealed associations with genetic polymorphisms modulations of genes involved directly (COMT, DRD2 and DAT) or indirectly (AKT1) to dopamine pathways. The most consistent finding was with COMT rs4680, where the presence of the Val allele was associated with a higher risk for cannabis-induced psychosis. This higher susceptibility was also reported for AKT1 (rs2494732) with the CC genotype. Of note, the only genome-wide association study identified a significant signal close to the cholinergic receptor muscarinic 3 represented by rs115455482 and rs74722579 predisposing to cannabis-induced hallucinations and remarkably no dopaminergic target was found.

CONCLUSION

Actual evidence supports the role of dopamine in cannabis induced psychosis. However, most of genetic polymorphism studies have as a starting point the pre-existing dopaminergic theoretical basis for psychosis. This alerts to the importance of more broad genetic studies. Integrate genetic results into biological systems may enhance our knowledge of cannabis induced psychosis and could help in the prevention and treatment of these patients.

Longitudinal course of mental health symptoms among veterans with and without cannabis use disorder

OBJECTIVE

Cannabis use disorder (CUD) is the most common non-alcohol related substance use disorder (SUD) in the United States and is especially prevalent among returning veterans. The long-term mental health correlates of CUD remain unknown, which is significant given the rise in legalization and also recreational and medicinal cannabis use nationally.

METHOD

Using a gender-balanced, national sample of 1,649 veterans (n = 115 with CUD; 75.2% White; M age = 37.49, SD = 9.88), we used latent growth curve modeling to examine posttraumatic stress disorder (PTSD) symptom severity, depressive symptoms, generalized anxiety, alcohol use, and psychosocial functioning between veterans with versus without a prior diagnosis of CUD over five time points, spanning an average of 7 years.

RESULTS

Returning veterans with CUD compared to those without reported higher alcohol use, depression, anxiety, PTSD symptom severity, and worse psychosocial functioning at baseline. We observed nonlinear change across each outcome. We also found that CUD moderated change in alcohol use (quadratic: b = -.129, p < .001) and PTSD symptoms (quadratic: b = -.280, p = .019), such that individuals with CUD evidenced decelerated change and worse outcomes relative to veterans without a previously documented CUD diagnosis. Trajectories of depression, anxiety, and psychosocial functioning were similar across individuals with versus without CUD.

CONCLUSIONS

In the first long-term and longitudinal evaluation of mental health and alcohol use course among returning veterans, CUD was associated with worse and more persistent alcohol use and PTSD symptom severity over time. These data have implications for clinical assessment, case conceptualization, and treatment of veterans and may inform efforts to offset risk for hazardous drinking and PTSD following a diagnosis of CUD.

Identifying archetypal cannabis consumers to inform drug policy design: a Q-sort assessment of young adults' attitudes in Mexico City's metropolitan area

Background

As the legalization of cannabis moves forward in many countries, it is important to highlight the potential harm that excessive use can cause on young consumers. Crafting effective policy interventions to reduce the harm stemming from excessive use requires an understanding of the attitudes and motivations of young consumers.

Methods

This article uses Q methodology to study four aspects of cannabis use among young adults from Mexico City’s metropolitan area: motivations for use, perceived consequences of use, reasons that would increase willingness to reduce consumption, and attitudes towards government regulation. A total of 110 cannabis users between 18 and 21 years old were recruited using chain-referral sampling. Using a Q methodology, we captured the relative importance that participants assigned to a series of statements and identified archetypal profiles of young adults who use cannabis for each of the four aspects mentioned above.

Results

The sample for this research study included 76 men and 34 women. The average age of participants was 20 years old, and the average age when cannabis consumption started was 15 years old. For each of the four Q-sort factor analyses, we identified 4 distinct factors based on explained variance and interpretability. The Q factor analysis indicated that attenuation of a negative affect (i.e., anxiety, stress) and relaxation were primary motivations for cannabis use. Understood consequences of cannabis use ranged across aspect-archetype, reflecting legal (i.e., interacting with law enforcement), financial, familial (i.e., disappointing family members), and educational performance concerns. Participants indicated that finding alternative relaxation strategies, receiving credible evidence of the health harms of cannabis use, increased financial burden of purchasing, and increased inaccessibility of cannabis products would motivate reductions in use. Across archetypes, participants indicated a willingness to comply with cannabis policies which are simple and easy to understand, which do not lead to discrimination or law enforcement involvement, and which provide for legal places to purchase and use safe (i.e., free of adulterants) cannabis products.

Conclusions

We posit that these archetypes could be useful to inform cannabis policy design. As the study reveals, participants’ cannabis use was primarily motivated by perceived improvements to mental health. Furthermore, participant responses indicated that they viewed cannabis use as a health matter, not a criminal one. Policies which aim to promote alternative mental health wellness and relaxation mechanisms, which aim to improve communication of potential health harms of cannabis, and which allow for the safe and legal purchase and use of cannabis may be effective in reducing cannabis-associated harms. Though our findings shed light on important aspects of cannabis users’ attitudes and perspectives, the sample size does not allow for a generalization of the findings and the drawing of conclusions about the population under scrutiny. Further research should consider the application of the Q methodology used in this article to a larger and more representative sample of cannabis users.

Unpacking the Construct of Dysregulated Behaviors Using Variable-Centered and Person-Centered Analytic Approaches

Dysregulated behaviors (e.g., alcohol and drug use, aggression, self-harm, gambling, binge eating) occur frequently and can be severely costly to individuals and society. Yet, little is known about the construct of dysregulated behaviors, including (a) whether it is distinct from related constructs such as compulsive behaviors and sensation-seeking, (b) whether its components share common correlates (e.g., impulsigenic traits, reward sensitivity, and emotion dysregulation), and (c) identify and describe patterns of dysregulated behaviors. To address these gaps in the literature, this study used variable-centered and person-centered analyses in a racially diverse sample of undergraduates (n = 338). In support of evidence distinguishing dysregulated behaviors from related constructs, correlational analysis indicated that the associations with compulsive behaviors were small and nonsignificant. In terms of construct validity, we found relatively strong and consistent evidence for impulsigenic traits across dysregulated behaviors but relatively inconsistent evidence for associations with reward sensitivity and emotion dysregulation. Finally, person-centered analysis indicated the presence of three classes characterized by high dysregulated behavior, low dysregulated behavior, and aggressive self-harm behavior. The likelihood of being classified in these classes differed considerably based on impulsigenic traits and emotion dysregulation. These results may have implications for the classification and treatment of dysregulated behaviors. Taken together, this study advances our understanding of dysregulated behaviors and sets the stage for further theory development and hypothesis testing regarding the onset, maintenance, and treatment of dysregulated behaviors.Supplemental data for this article is available online at https://doi.org/10.1080/10826084.2022.2026966 .

The buffering role of higher romantic relationship satisfaction on the association of hazardous drinking with PTSD and depression symptoms among female military service members/veterans

Studies show that more positive relationship satisfaction can mitigate the effects of posttraumatic stress disorder (PTSD) and depression severity on hazardous drinking in military samples. However, past studies were not circumscribed to female service members/veterans (SM/V), who represent the fastest growing demographic in the military. Moreover, studies did not examine moderators of specific symptom clusters of PTSD and depression with hazardous drinking. Indeed, recent studies have shown that the more depressive and cognitive clusters are associated with greater dysfunction. The current study extended this literature in a convenience sample of 584 female SM/V who completed self-report measures of hazardous drinking, PTSD, depression, and relationship satisfaction. PTSD or depression severity, relationship satisfaction, and their interaction, were examined as correlates of hazardous drinking after accounting for relationship, demographic, and military characteristics. For both overall PTSD and depression severity, higher relationship satisfaction weakened their association with hazardous drinking. Such results were consistent when global scores were replaced with PTSD-related negative alterations in cognitions and mood and somatic depression symptom clusters, but not for PTSD-related dysphoric arousal, anhedonia, or non-somatic depression symptom clusters. Findings suggest that to lessen the association of PTSD or depressive symptoms with problematic drinking, interventions aimed at improving relationship satisfaction may be worth considering among women in relationships. Moreover, symptom cluster analyses show that the cognitive and depressive components of PTSD, as well as the physical symptoms of depression, are most problematic, pinpointing specific areas of function on which to intervene.

Combined use of alcohol and cannabis: Introduction to the special issue

OBJECTIVE

Combined use of alcohol and cannabis has increased in recent years among certain age groups, and it is well established that individuals who use both alcohol and cannabis (especially if they use both at the same time) are at increased risk for substance-related harms relative to individuals who use only one substance. Far less attention has been placed on the patterns, predictors, and psychological processes associated with alcohol and cannabis co-use, which may inform prevention and intervention programming. Accordingly, this special issue was assembled to advance our understanding of the characteristics and consequences of combined use of alcohol and cannabis.

METHOD

In this introductory article, the Guest Editors present the background for this work and provide an overview of the 14 articles that comprise this special issue.

RESULTS

Studies contained in this special issue capitalize on a variety of methodologies, with a particular focus on investigating typologies of alcohol and cannabis co-use, clarifying motivational and social contexts of co-use, and tracking co-use in daily life via daily diary and ecological momentary assessment designs. Experimental and neuroimaging examinations of co-use are also included. Collectively, the studies generally provide evidence that combined use of alcohol and cannabis is associated with unique characteristics, predictors, consequences, and psychological processes relative to single-substance use.

CONCLUSIONS

The studies in this special issue provide new insight into combined use of alcohol and cannabis. They also highlight a number of promising avenues for future inquiry as the literature on alcohol and cannabis co-use continues to grow. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Drinking less on cannabis use days: The moderating role of UPPS-P impulsive personality traits

Objective: Several studies suggest that alcohol and cannabis co-users are heavier drinkers and experience more alcohol-related consequences. However, day-level associations between co-use and drinking levels are mixed. One reason may be that individual characteristics moderate the daily impact of using alcohol alone or in conjunction with cannabis. The theory would suggest that highly impulsive individuals may drink more on co-use days, yet this assertion remains untested. Therefore, the current study tested whether impulsivity moderated the effect of co-use on same-day drinking quantity within veterans, a high-risk sample for substance use and impulsivity. Method: In a longitudinal observational study, co-using veterans (N = 139) completed three semi-annual assessments reporting on their daily drinking quantity and cannabis use via Timeline Followback (Observations = 19,245) and impulsivity via the UPPS-P. Mixed effect modeling was used to test hypotheses that co-use (compared to alcohol-only) days would be associated with heavier drinking for those high (but not low) in positive and negative urgency. Results: Significant interactions were found for positive urgency (PU) and lack of perseverance (LP), such that individuals at mean and low levels of PU and LP drank less on co-use (compared to alcohol-only) days. There were no significant interactions for other UPPS-P impulsivity facets. Conclusion: Findings are consistent with a substitution/compensatory effect for individuals at mean and low levels of both UPPS-P facets, and may be a byproduct of frequent cannabis use in veterans. In contrast, findings suggest that co-use and alcohol-only days may be characterized by similarly high levels of drinking for highly impulsive individuals.

Comparative associations of problematic alcohol and cannabis use with suicidal behavior in U.S. military veterans: A population-based study

Alcohol use disorder (AUD) and cannabis use disorder (CUD) are each associated with increased suicidal behavior, but it is unclear how their comorbidity relates to suicide risk. Understanding these associations in U.S. military veterans is especially important, given their heightened risk for suicide, high prevalence of AUD, and increasing access to cannabis. We compared associations of probable AUD, CUD, and AUD/CUD with suicide ideation, plan(s), and attempt(s) in a nationally representative sample of 4,069 veterans surveyed in 2019-2020 as part of the National Health and Resilience in Veterans Study. Among veterans who screened positive for current AUD, 8.7% also screened positive for current CUD. Among veterans who screened positive for current CUD, 33.3% screened positive for current AUD. Current and lifetime positive screens for AUD, CUD, and AUD/CUD were each strongly and independently associated with past-year suicide ideation and lifetime suicide ideation, plan(s), and attempt(s) [odds ratios (ORs) = 1.6-8.7]. Relative to veterans who screened positive for AUD only, veterans who screened positive for AUD/CUD and CUD only had higher odds of past-year suicide ideation (AUD/CUD: OR = 3.3; CUD only: OR = 2.4), lifetime suicide ideation (AUD/CUD: OR = 1.9; CUD only: OR = 2.6) and lifetime suicide plan(s) (AUD/CUD: OR = 1.7; CUD only: OR = 6.1). Collectively, findings suggest that screening positive for CUD might be an especially strong indicator of suicide ideation and planning in veterans with and without AUD, independent of sociodemographic, military, trauma, and other psychiatric factors. These findings underscore the importance of routine screening for CUD in suicide prevention efforts, especially as cannabis becomes more widely available.
