An examination of sociodemographic correlates of ecstasy use among high school seniors in the United States

Ecstasy, molly, MDMA: What health practitioners need to know about this common recreational drug

3,4-methylenedioxymethamphetamine (MDMA; commonly referred to as "ecstasy" or "molly") is a substituted amphetamine drug that is used recreationally for its acute psychoactive effects, including euphoria and increased energy, as well as prosocial effects such as increased empathy and feelings of closeness with others. Acute adverse effects can include hyperthermia, dehydration, bruxism, and diaphoresis. Post-intoxication phenomena may include insomnia, anhedonia, anxiety, depression, and memory impairment, which can persist for days following drug cessation. MDMA acts as a releasing agent for monoamine neurotransmitters, including dopamine (DA), norepinephrine (NE) and serotonin (5-HT), by interfering with vesicular storage and transporter function, thus increasing extracellular levels of DA, NE, and 5-HT. Medical intervention in response to adverse events is complicated by the fact that illicitly-acquired MDMA is frequently adulterated, contaminated, or outright replaced with other psychoactive drugs such as synthetic cathinones ("bath salts") or methamphetamine, often unknown to the person using the drug. This review provides background on the legal status of MDMA and its use patterns, including proposals for its use as an adjunct in psychotherapy. It also discusses the pharmacological properties, mental and physical health effects, and interactions of MDMA with other drugs, with special focus on harm reduction strategies. This information will help healthcare providers assess adverse health effects related to MDMA/ecstasy use in order to facilitate appropriate treatment strategies and improve patient outcomes.

Prevalence and Correlates of Past Year Ecstasy/MDMA Use in the United States

OBJECTIVES

3,4-Methylenedioxymethamphetamine (MDMA) (also known as "ecstasy" or "Molly") has regained attention in recent years for its efficacy in treating posttraumatic stress disorder, and the drug was granted breakthrough therapy designation for such use by the US Food and Drug Administration in 2017. However, little is known about the current epidemiology of recreational ecstasy/MDMA use.

METHODS

We estimated past-year prevalence and correlates of ecstasy/MDMA use based on a representative sample of noninstitutionalized US individuals 12 years or older from the 2015-2020 National Survey on Drug Use and Health (N = 315,661).

RESULTS

An estimated 0.9% (95% confidence interval [CI] = 0.9-1.0) of individuals used ecstasy/MDMA in the past year. Compared with those ages 35-49 years, all younger age groups were at increased odds for use, while those older than 50 years (adjusted odds ratio [aOR] = 0.14, 95% CI = 0.08-0.23) were at low odds for use. Compared with heterosexual men, those identifying as bisexual women (aOR = 1.32, 95% CI = 1.02-1.72) were at increased odds for use, and compared with White individuals, those identifying as Asian (aOR = 1.92, 95% CI = 1.42-2.59), Black (aOR = 1.70, 95% CI = 1.41-2.06), or multiracial (aOR = 1.61, 95% CI = 1.19-2.16) were at increased odds for use. Past-year use of other drugs (e.g., cannabis, ketamine), prescription drug misuse (e.g., pain relievers, stimulants), nicotine dependence (aOR = 1.21, 95% CI = 1.00-1.45), and alcohol use disorder (aOR = 1.41, 95% CI = 1.25-1.58) were also associated with increased odds for use.

CONCLUSIONS

While use of ecstasy/MDMA continues to be relatively rare, findings from this study can help inform prevention and harm reduction strategies, especially among certain subpopulations that are at high risk for use.

Subtypes of Bullying and Types of Substance Use among Urban African American Adolescents: Who Is Likely to Use What?

The present study examined the types of drugs likely to be used by bullies, victims, and bully/victims. Participants comprise African American adolescents from three high schools, one youth church group, two community youth programs, and four public venues in low-income communities in Chicago's Southside. A series of logistic regression analyses and latent class analyses were employed. Victims are likely to use alcohol, marijuana, and lean/krokodil. Bullies were likely to use alcohol and marijuana. Bully/victims were not at risk of any of the substances. Our LCA findings revealed a lower occurrence of substance use among victims although 30% used alcohol and marijuana; more than half of bullies showed high levels of alcohol, marijuana, and lean/krokodil use; a diverse pattern of drug use was shown among bully/victims although their lean/krokodil and crack/cocaine use was higher than other subgroups of bullying. The drugs of choice for African American bullies, victims, or bully/victims are variable.

Physical and psychosocial factors associated with psychostimulant use in a nationally representative sample of French adolescents: Specificities of cocaine, amphetamine, and ecstasy use

PURPOSE

Patterns of psychostimulant (PST) use, psychological and physical factors, and family relationships were investigated in a nationally representative sample of adolescents. The differences between users of cocaine (Cc), ecstasy/MDMA, and amphetamine (EA) were analyzed, taking into account gender differences.

METHODS

Substance use, psychological factors (lifetime suicide attempts, suicidal thoughts in the previous year, visits to a mental health professional), physical factors (health and body shape perceptions (BSP), body mass index (BMI)), and family relationships (existence of disagreements with parents, relationships with mother and father) were investigated in 26,351 17-year-old French adolescents.

RESULTS

Lifetime suicidal behavior was strongly associated with EA use only. Suicidal ideation in the previous year was associated with Cc use among both boys and girls and associated with EA use among girls. Compared to Cc users, more EA users were overweight, while more Cc users were underweight compared to EA users. BSP, BMI, and EA use were related in girls only. Having a good or very good relationship with both mother and father was negatively associated with Cc use in boys and girls. Girls who had a good or very good relationship with their fathers seemed to be less prone to use EA. Boys with a good or very good relationship with their mothers seemed to be less prone to use EA.

CONCLUSION

The results of the present study could serve as a basis for prevention and harm reduction strategies/programs targeting youth use and for the adaptation of these strategies/programs according to substance and gender.

Increased iNOS and Nitrosative Stress in Dopaminergic Neurons of MDMA-Exposed Rats

Several mechanisms underlying 3,4-Methylenedioxy-N-methylamphetamine (MDMA) neurotoxicity have been proposed, including neurochemical alterations and excitotoxicity mediated by reactive oxygen species (ROS), nitric oxide (NO), and reactive nitrogen species (RNS). However, ROS, NO, and RNS sources in the brain are not fully known. We aimed to investigate possible alterations in the expression of the ROS producer NOX enzymes (NOX2, NOX1, and NOX4), NO generators (iNOS, eNOS, and nNOS), markers of oxidative (8-hydroxy-2'-deoxyguanosine, 8OHdG), and nitrosative (3-nitrotyrosine, NT) stress, as well as the colocalization between cells positive for the dopamine transporter (DT1) and cells expressing the neuronal nuclei (NeuN) marker, in the frontal cortex of rats receiving saline or MDMA, sacrificed 6 h, 16 h, or 24 h after its administration. MDMA did not affect NOX2, NOX1, and NOX4 immunoreactivity, whereas iNOS expression was enhanced. The number of NT-positive cells was increased in MDMA-exposed animals, whereas no differences were detected in 8OHdG expression among experimental groups. MDMA and NT markers colocalized with DT1 positive cells. DT1 immunostaining was found in NeuN-positive stained cells. Virtually no colocalization was observed with microglia and astrocytes. Moreover, MDMA immunostaining was not found in NOX2-positive cells. Our results suggest that iNOS-derived nitrosative stress, but not NOX enzymes, may have a crucial role in the pathogenesis of MDMA-induced neurotoxicity, highlighting the specificity of different enzymatic systems in the development of neuropathological alterations induced by the abuse of this psychoactive compound.

3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) use and transitions to injection drug use among street-involved youth

Background: Despite the popularity of 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) among young people across North America and Europe, MDMA is rarely explored in studies of young people at high risk of injecting drugs. We conducted a study among street-involved youth who use illicit drugs in Vancouver, Canada, to understand if use of MDMA is associated with initiation of injection drugs. Methods: We followed injection-naïve participants in the At-Risk Youth Study (ARYS), an ongoing prospective cohort of street-involved youth aged 14-26 who use illicit drugs. Bivariate and multivariate extended Cox models with time-updated variables were used to examine the association between MDMA use and initiation of injection drug use between September 2005 and May 2015. Results: Among 483 youth, 306 (63.4%) had a history of MDMA use and 218 (45.1%) had used MDMA in the previous 6 months at baseline. A total of 105 (21.7%) youth initiated injection drug use over the 10-year period, yielding an incidence density of 8.51 (95% confidence interval [CI]: 6.96-10.30) per 100 person-years. MDMA use was not significantly associated with initiating injection drugs at the bivariate (hazard ratio: 0.93, 95% CI: 0.61-1.42) or multivariate (adjusted hazard ratio: 0.88, 95% CI: 0.57-1.35) level, after adjusting for socio-demographic and substance use confounders. Conclusions: Amid ongoing frequent use of MDMA among some young people in North America, we did not observe an elevated risk of injection initiation among those who used MDMA in this cohort of street-involved youth.

The Development of Ecstasy Use Among Juvenile Offenders and Risk Factors for Predicting Heterogeneity: A Group-Based Approach

This study seeks to examine heterogeneity in developmental patterns of ecstasy use during adolescence and early adulthood among juvenile offenders and identify risk factors predicting development. Group-based trajectory modeling was utilized to elucidate heterogeneity in developmental patterns of ecstasy use. Multinomial logistic regression was utilized to identify covariates that affected the risk of assignment to groups elucidated in the trajectory model. A five-group model was found to best fit the ecstasy use data. Baseline measures of deviant peer association, self-control, other drug use, and race were identified as important risk factors predicting patterns of development. Risk of ecstasy use may be greatest for some juvenile offenders during critical periods of the life course and some social and personal characteristics that may elevate risk. Stability that is characteristic of self-control may be highly relevant for predicting persistent ecstasy use during adolescence and early adulthood.

Nonmedical prescription drug use among African Americans who use MDMA (ecstasy/molly): Implications for risk reduction

Recent data suggest that both nonmedical prescription drug and MDMA (ecstasy/molly) use have risen among African Americans. However, studies investigating these two forms of drug use among African Americans are rare. As a result, very little is known about African-American MDMA users and their nonmedical use of prescription medications. The primary goal of this study, therefore, was to describe patterns of nonmedical prescription drug use among African Americans who use MDMA. We also assessed alcohol and illicit drug use among the sample. Surveys (n=100) and in-depth interviews (n=15) were conducted with African-American young adults in Southwest Florida between August 2014 and November 2015. Survey results show that a significant proportion of the sample used MDMA in conjunction with prescription medications (benzodiazepines=59%; opioids=35%; stimulants=13%). Qualitative findings suggest that benzodiazepine medications were used to alleviate MDMA comedown symptoms, opioids were used to achieve a different quality high, and stimulants were used to provide added energy throughout the night. These results suggest that treatment practitioners and harm reduction professionals should pay particular attention to informing users of the potential hazards of combining MDMA with prescription medications. Although additional research is clearly needed, these findings are an important first step towards understanding both nonmedical prescription drug and MDMA use among African Americans, and could be used to tailor treatment and risk reduction interventions to this population.

Characterizing users of new psychoactive substances using psychometric scales for risk-related behavior

INTRODUCTION

Studies investigating risk-related behavior in relation to new psychoactive substance (NPS) use are sparse. The current study investigated characteristics of NPS users by comparing risk-related behavior of NPS users to that of illicit drugs (ID) users and licit substances users and non-users (NLC) users.

METHODS

In this cross-sectional study we included 528 individuals across an age range of 18-72years. Using a web-based questionnaire we collected self-report data on substance use, sensation seeking, impulsivity, peer substance use and risk perception of substance use.

RESULTS

NPS and ID users had a higher level of sensation seeking compared to NLC users (NPS users: p<0.001; ID users: p<0.001). NPS users (p<0.001), but not ID users (p=0.16), had increased levels of impulsivity compared to NLC users. NPS users had significantly higher scores for sensation seeking (F_1,423=51.52, p<0.001) and impulsivity (F_1,423=6.15, p=0.01) compared to ID users. Additionally, NPS users had significantly more peers who use substances compared to ID and NLC users. Also, NPS and ID users had lower risk perception for most substances than NLC users. NPS users had lower risk perception for most substances than ID users.

CONCLUSIONS

The findings highlight that NPS users show substantial more risk-related behavior than both ID and NLC users. Therefore, NPS users might be considered as a distinctive group of substance users that need another approach in terms of prevention.

Self-Reported Ecstasy/MDMA/"Molly" Use in a Sample of Nightclub and Dance Festival Attendees in New York City

BACKGROUND

Ecstasy (MDMA) use has regained popularity in the United States, particularly in the form of "Molly," which is often marketed as pure MDMA. Surveys have generally not included "Molly" in the definition of ecstasy, so rates of use may be underestimated. As popularity of ecstasy increases, research is needed to examine use among those at highest risk for use-nightlife attendees.

METHODS

We surveyed 679 young adults (age 18-25) entering nightclubs and festivals holding electronic dance music (EDM) parties in New York City in 2015. A variation of time-space sampling was utilized. We examined prevalence and correlates of self-reported lifetime ecstasy use.

RESULTS

Self-reported lifetime ecstasy use was common (42.8%, 95% CI: 32.8, 52.7). Use was most common among older participants, frequent party attendees, and those reporting higher levels of exposure to users. Those surveyed outside of festivals were less likely to report use compared to those surveyed outside of nightclubs (AOR = 0.37, p = .015). Over a third of ecstasy users (36.8%)reported use in pill, powder, and crystal form. Ecstasy users were also more likely to report use of other drugs, including novel psychoactive substances (e.g., 2C series drugs, synthetic cathinones ["bath salts"]). Half (50.4%) reported suspecting (21.9%) or finding out (28.5%) that their ecstasy had ever contained a drug other than MDMA.

CONCLUSION

A large percentage of nightlife attendees in NYC report lifetime ecstasy use. Findings should inform prevention and harm reduction programming. Further research is needed as ecstasy continues to change (e.g., in form, purity, and name).

Hallucinogen Use Disorders

Use of hallucinogenic substances as a public health concern has increased over the past decade. Among adolescents, there are increasing emergency department presentations for intoxication with these drugs, contrary to decreasing reported use of classical hallucinogens such as LSD. Academic and governmental groups have monitored use of hallucinogens, highlighting a notable change in perceptions about use among adolescents thought to contribute to these trends. Special populations and religious groups, though, have been granted governmental permission to use hallucinogens for their cultural practices. Novel designer hallucinogens have gained popularity and may have serious medical and psychological side effects from use.

Molly users versus nonusers in a sample of college alcohol drinkers: Differences in substance-related harms and sensation seeking

BACKGROUND

Molly is one form of MDMA (3,4-methylenedioxymethamphetamine) that is touted to be more "pure" and potentially less harmful than other forms, such as ecstasy. Media reports and case studies suggest that this drug is popular among college students and is related to adverse health problems. The current study sought to address the knowledge gaps about Molly by examining whether users differ in substance use outcomes and sensation seeking than nonusers. Specifically, this study tested whether Molly users engaged in heavier use of other substances and experienced more substance-related harms in general than nonusers. Further, the current study investigated whether Molly users exhibited higher levels of sensation seeking than nonusers. Lastly, this study examined whether Molly user status would be associated with substance-related harms beyond the confounding influence of other substance use and trait sensation seeking.

METHODS

Participants were 710 (71.9% female) college alcohol drinkers who completed self-report surveys about substance use (i.e., Molly, alcohol, and other drug use), substance-related problems, and sensation seeking.

RESULTS

Results revealed that approximately 12% of the sample reported lifetime Molly use. Molly users compared with nonusers reported higher levels of other drug use, alcohol use, substance-related problems, and sensation seeking. Further, Molly users reported experiencing poorer substance use outcomes (e.g., blacking out, academic/occupational problems, and withdrawal symptoms) after accounting for sensation seeking and other substance use.

CONCLUSIONS

These findings indicate that Molly users are higher in sensation seeking and that use is uniquely related to greater risk for substance-related harms. These preliminary findings demonstrate a need for correcting possible misperceptions regarding the purity of Molly and educating users on the potential for experiencing associated harms. Such information could be used to develop efficacious prevention programming for college students.

Characteristics of novel psychoactive substance exposures reported to New York City Poison Center, 2011-2014

BACKGROUND

Novel psychoactive substances (NPS) are emerging at an unprecedented rate. Likewise, prevalence of use and poisonings has increased in recent years.

OBJECTIVE

To compare characteristics of NPS exposures and non-NPS-drug-related exposures and to examine whether there are differences between exposures involving synthetic cannabinoid receptor agonists (SCRAs) and other NPS.

METHODS

Poison control center data from the five counties of New York City and Long Island were examined from 2011-2014. We examined prevalence and characteristics of NPS exposures (classified as intentional abuse) and compared characteristics of cases involving SCRAs and other NPS.

RESULTS

Prevalence of NPS exposures was 7.1% in 2011, rising to 12.6% in 2014. Most exposures (82.3%) involved SCRA use. The second and third most prevalent classes were phenethylamines/synthetic cathinones ("bath salts"; 10.2%) and psychedelic phenethylamines (4.3%). Compared to other drug-related exposures (i.e. involving licit and illicit drugs), those who used NPS were more likely to be younger, male, and to have not co-used other drugs (ps < 0.001). SCRA exposures increased sharply in 2014 and the mean age of users increased over time (p < 0.01). Females exposed to SCRAs were younger than males (p < 0.001), and in 2014, individuals exposed to SCRAs were more likely to report concomitant use of alcohol than users of other NPS (p = 0.010). Users of other NPS were more likely than SCRA users to report concomitant use of ecstasy/3,4-methylenedioxymethamphetamine (MDMA)/"Molly" (p < 0.001).

CONCLUSION

Exposures reported to the poison center that involve NPS are increasing and the majority involve SCRAs. These findings should inform prevention and harm reduction approaches.

Illicit drug use among rave attendees in a nationally representative sample of US high school seniors

BACKGROUND

The popularity of electronic dance music and rave parties such as dance festivals has increased in recent years. Targeted samples of party-goers suggest high rates of drug use among attendees, but few nationally representative studies have examined these associations.

METHODS

We examined sociodemographic correlates of rave attendance and relationships between rave attendance and recent (12-month) use of various drugs in a representative sample of US high school seniors (modal age: 18) from the Monitoring the Future study (2011-2013; Weighted N=7373).

RESULTS

One out of five students (19.8%) reported ever attending a rave, and 7.7% reported attending at least monthly. Females and highly religious students were less likely to attend raves, and Hispanics, students residing in cities, students with higher income and those who go out for fun multiple times per week were more likely to attend. Rave attendees were more likely than non-attendees to report use of an illicit drug other than marijuana (35.5% vs. 15.6%, p<0.0001). Attendees were more likely to report use of each of the 18 drugs assessed, and attendees were more likely to report more frequent use (≥6 times) of each drug (ps<0.0001). Controlling for sociodemographic covariates, frequent attendance (monthly or more often) was associated with higher odds of use of each drug (ps<0.0001). Frequent attendees were at highest risk for use of "club drugs."

DISCUSSION

Findings from this study can help inform prevention and harm reduction among rave attendees at greatest risk for drug use.

Prevalence and correlates of hashish use in a national sample of high school seniors in the United States

BACKGROUND

Cannabis (marijuana) use and acceptance towards use are increasing in the US, and state-level policies are becoming more liberal. A wealth of research has been conducted to examine risk factors for use; however, studies rarely differentiate between different forms of marijuana.

OBJECTIVE

We sought to determine prevalence of use and delineate who is at risk for use of hashish, a more potent form of marijuana.

METHODS

We examined data from a nationally representative sample of high school seniors in the Monitoring the Future study (2007-2011; weighted n = 10 597). We determined how sociodemographic factors and reasons for marijuana use correlated with recent (12 month) hashish use.

RESULTS

Prevalence of recent hashish use was 6.5% and it was used by 18.3% of recent marijuana users. Hashish and other marijuana use tended to share many of the same correlates; however, associations were often stronger for hashish use. Females were consistently at low risk for use and users of other drugs were consistently at high risk for use. Black students tended to be at low risk for hashish use. Low risk of identifying as Hispanic or religious and high risk of higher personal income or going out more evenings per week for fun disappeared when controlling for other drug use. Using marijuana because the student felt he/she was "hooked" nearly doubled the odds for hashish use.

CONCLUSIONS

This was the first national study to examine prevalence and correlates of hashish use. These findings can inform prevention in a time of increasing popularity of marijuana use.

Synthetic cannabinoid use in a nationally representative sample of US high school seniors

BACKGROUND

Synthetic cannabinoids are marketed as "legal highs" and have similar effects to cannabis (marijuana). Although prevalence of synthetic cannabinoid use is now declining in the US, use has been associated with tens of thousands of poisonings and hospitalizations, particularly among teens. It is important to examine which teens are at highest risk for use of these new, potentially deleterious drugs as they are understudied and continue to emerge.

METHODS

Data were analyzed from a nationally representative sample of high school seniors in the Monitoring the Future study (2011-2013; Weighted N = 11,863; modal age: 18). Bivariable and multivariable models were used to delineate correlates of recent (12-month) synthetic cannabinoid use.

RESULTS

Ten percent reported any recent use and 3% reported more frequent use (used ≥ 6 times). Females were at low odds for use and going out 4-7 evenings per week for fun consistently increased odds of use. Black and religious students were at low odds of use until controlling for other drug use, and higher income increased odds of use until controlling for other drug use. Lifetime use of alcohol, cigarettes and other illicit drugs all robustly increased odds of use, but frequency of lifetime marijuana use was the strongest correlate with more frequent use further increasing odds of synthetic cannabinoid use. Only 0.5% of non-marijuana users reported use of synthetic cannabinoids.

CONCLUSIONS

This is among the first national studies to delineate correlates of synthetic cannabinoid use. Results can inform national and local efforts to prevent use and adverse consequences resulting from use.
