9/8/21--Marijuana use continued to rise among college students over the past five years and remained at historically high levels among same-aged peers who are not in college in 2020, according to survey results from the 2020 Monitoring the Future (MTF) panel study. This represents the highest levels of marijuana use recorded since the 1980s. Read

9/7/21--Using data from the Youth Risk Behavior Survey (YRBS) for the period 1993-2017, Anderson et al found that RML adoption was associated with an 8% decrease in the odds of marijuana use among high school students. These authors, however, had prelegalization and postlegalization data from only 7 states and pre– and post–recreational sales data from only 3 states, calling into question the generalizability of their results. Read

8/30/21--Data on screening and linkage to treatment within the justice system is lacking. Therefore, to further inform the juvenile justice behavioral health cascade of care, this study examined factors associated with identified problematic substance use and treatment referral using two screening tools. Study results indicates that regardless of tool used, treatment referral was low, highlighting the need for accurate identification of treatment needs of substance-using, justice-involved youth. Interventions to facilitate referrals for youth with problematic substance use are needed. Read

8/2/21--This study was designed to investigate changes in cannabis modes of use and associated factors across the federal legalization of recreational cannabis use for adults in Canada. Results indicate that multi-modal cannabis use increased among Canadian youth, and its association with other substance use and depressive symptoms may indicate clustering of additional harms. Read

7/27/21--This study was designed and conducted to examine how adolescent substance use and perceived availability of substances have changed during the COVID-19 pandemic. Results from longitudinal data indicate that perceived availability of marijuana, alcohol, and vaping devices declined at historic rates during the pandemic of 2020. Lack of accompanying reductions in prevalence for marijuana and binge drinking demonstrates the substantial challenges facing a supply-side approach to the reduction of adolescent use of these substances. Read

7/1/21--According to a new study, young adults’ use of cannabis and alcohol tends to rise and fall together, rather than one substance substituting for the other. Legalizing recreational cannabis use has raised the possibility that cannabis may substitute for risky drinking or other substance use, potentially with less severe public health consequences. Alternatively, legalizing cannabis might lead to higher consumption of both cannabis and alcohol, with escalating problematic effects. Read

6/21/21--A study designed to examine how adolescent substance use and perceived availability of substances have changed during the COVID-19 pandemic has concluded that perceived availability of marijuana, alcohol, and vaping devices declined at historic rates during the pandemic of 2020. Lack of accompanying reductions in prevalence for marijuana and binge drinking demonstrates the substantial challenges facing a supply-side approach to the reduction of adolescent use of these substances. Read

5/19/21--The 2020 findings from the largest European project in the science of wastewater analysis are revealed today in Wastewater analysis and drugs — a European multi-city study, published by the Europe-wide SCORE group, in association with the EU drugs agency (EMCDDA). The project analyzed wastewater in 82 European cities (18 countries) to explore the drug-taking behaviors of their inhabitants. While the 2019 results pointed to an overall rise in the detection of stimulants, the 2020 findings are more mixed, with diverse geographical and temporal patterns seen across the study locations. Read

5/3/21--In this cohort study of tobacco use behaviors among ninth- and tenth-grade students enrolled at 8 public high schools in Northern California from March 2019 to February 2020 and followed up from September 2019 to September 2020, a reduction in e-cigarette use occurred independently of COVID-19 stay-at-home restrictions, but persistent cannabis and alcohol use suggest continued need for youth substance use prevention and cessation support. Read

4/22/21--Growing evidence indicates that youths exposed to opioids for legitimate medical purposes have an increased risk of opioid use disorders in the future. According to a study, adolescents and young adults are especially susceptible to negative consequences of opioid misuse because of their ongoing biological, social, and psychological development. Read

4/22/21--Results of a study examining distinct patterns of opioid prescribing following the first prescription using group-based trajectory modeling and examine the patient-, clinician-, and prescription-level factors that may be associated with trajectory membership during the first year indicate 2 trajectories associated with elevated risk for persistent opioid receipt within 12 months following first opioid prescription. The high-risk trajectory was characterized by older age at time of first prescription, and longer and more potent first prescriptions. Read

4/6/21--In this longitudinal cohort study of 1108 men, both unadjusted and adjusted models showed that consumption of cannabis with a water pipe at baseline was associated with the use of other illicit drugs at follow-up compared with not using a water pipe. Read

3/17/21--According to this study, recreational cannabis legalization has not been followed by the slowing or reversing of concerning trends in youth cannabis use, suggesting that, so far, the Cannabis Act has not yet led to the benefits for youth envisioned in adopting a public health approach to legalization. Further monitoring will be essential in characterizing its longer-term effects as well as to track impacts of additional regulatory changes. Read

3/17/21--According to this study, among adults with children living in the home, cannabis use appears to be more common in US states with legalized cannabis use compared with states with no legal cannabis use. Recreational legalization appears to increase use among adults with children in the home broadly across nearly all sociodemographic groups, whereas the effect of legalization for medical use is heterogeneous by age and socioeconomic status. Read

2/15/21--Adolescents who live in California may be more likely to use marijuana since adult recreational marijuana use was legalized in 2016, according to a new report in the Journal of Studies on Alcohol and Drugs. The researchers who conducted the study suggest that recreational marijuana legalization may present increased opportunities for adolescents to obtain marijuana and that the increasing availability of non-smoking products such as edibles may prove appealing as well. Read

2/10/21--The Commonwealth Fund’s International Health Policy surveys fill important information gaps by polling patients and providers in 11 developed countries. For the first time, the survey included comparable information about behaviors affecting health (use of alcohol, tobacco, electronic vaping devices, cannabis and illicit drugs). Read

2/1/2021--According to a retrospective longitudinal examination across race/ethnicity, adolescents’ initial use of marijuana and inhalants may lead to substantial risks of using other drugs over time. It is therefore important to screen adolescent drug use comprehensively and provide early interventions to prevent an escalation to more detrimental drugs. The findings provide new evidence to support aspects of both the gateway and generalized risk drug use theories. Read

1/30/21--This study aims to examine trends in cannabis views and use among US adults who are alcohol abstainers, non-binge drinkers, and binge drinkers. Findings indicate that cannabis disapproval has decreased and cannabis use increased among alcohol abstainers, non-binge drinkers, and binge drinkers between 2002 and 2018. The impact of cannabis disapproval on use attenuated during the study period among drinkers but not among abstainers, suggesting that the effect of anti-cannabis attitudes may be weakening among those most likely to use cannabis. Read

1/29/21--This study expands beyond studies of outlet prevalence to find that, after controlling for outcomes 1 year prior, licensed and unlicensed outlets were associated with young adults' cannabis outcomes. The current study is among the first to find associations between cannabis use outcomes and density of cannabis outlets among young adults using data from two time points: preopening and postopening of recreational cannabis retailers. Read

1/25/21--According to research published in the peer-reviewed journal Addiction Research & Theory, teenagers with happy childhood memories are likely to drink less, take fewer drugs and enjoy learning. The findings, based on data from nearly 2,000 US high school students, show a link between how pupils feel about the past, present and future and their classroom behavior. This in turn influences their grades and risk of substance misuse. Read

1/26/21--This paper compares consequences of cannabis use initiated after high school with those of cannabis initiation in adolescence, with estimates of the proportion of adverse consequences accounted for by adult-onset and adolescent-onset cannabis users. Read

2/1/21--Prevalence of cannabis use has been increasing among select subgroups in the US; however, trend analyses typically examine prevalence of use across years.

11/20/20--It’s good news for health. But there is also a downside in the data: While alcohol use is falling among 18-to-22-year-olds, marijuana use is inching upward. The number of young adults using both alcohol and marijuana is also rising, heightening concerns about a future surge in substance abuse problems, new research shows. Read

10/6/20--In this repeated cross-sectional study including 71,756 young adults aged 22 to 23 years, the proportion of ever smokers who initiated cigarette smoking in early adulthood more than doubled between 2002 and 2018, and the proportion of daily cigarette smokers who transitioned to daily smoking in early adulthood also increased from 38.7% in 2002 to 55.9% in 2018. Read

10/6/20--This study by Barrington-Trimis et al used data from the National Survey on Drug Use and Health to examine the proportion of young adult cigarette smokers (aged 22-23 years) who initiated smoking in young adulthood from 2002 to 2018. Barrington-Trimis and colleagues found that during this period with population-level declines in cigarette smoking among youth and young adults, the average age of smoking initiation and the proportion of new initiates and daily smokers who were young adults increased. Read

10/27/20--According to the latest National Survey on Drug Use and Health, compiled by the Substance Abuse and Mental Health Services Administration, among people aged 12 years or older in 2019, 60.1% reported having used a substance during the past month. Yet, the proportion of adolescents aged 12 to 17 years who reported consuming alcohol in the past month declined from 17.6% in 2002 to 9.4% in 2019. During that period, past-month cigarette use decreased from 26% to 16.7% among people aged 12 years or older. Read

The study, published in the Journal of the American Geriatrics Society, found that of 568 patients surveyed, 15 percent had used cannabis within the past three years, with half of users reporting using it regularly and mostly for medical purposes. Read

10/8/20--According to a prospective cohort study, among US adults with problem substance use who use non‐medical opioids, the odds of opioid use appear to be approximately doubled on days when cannabis is used. This relationship does not appear to differ between people with moderate or more severe pain versus less than moderate pain, suggesting that Cannabis is not being used as a substitute for illegal opioids. Read

10/12/20--The findings of this study suggest that US colleges and communities should create and maintain supportive resources for young adults as the substance use landscape changes, specifically as alcohol abstinence, marijuana use, and co-use increase. Interventions for polysubstance use, alcohol use disorder, and marijuana use disorder may provide valuable opportunities for clinicians to screen for prescription drug misuse. Read

10/12/20--Between 2002 and 2018, the number of adults aged 18-22 in the U.S. who abstained from alcohol increased from 20% to 28% for those in college and from about 24% to 30% for those not in school, say researchers at the University of Michigan and Texas State University. And alcohol abuse among both groups decreased by roughly half. Read

8/14/20--Continuous surveillance of marijuana use in the perinatal period can inform clinical guidance, provider and patient education, and public health programs to support evidence-based approaches to addressing substance use. Yet, the American College of Obstetricians and Gynecologists and the American Academy of Pediatrics recommend refraining from marijuana use during pregnancy and lactation because evidence on safety and health effects are inconclusive or insufficient. Read

8/7/20--The overall prevalence of drug use reported in the UK has remained relatively stable throughout the last decade. However, the most recent surveys covering England and Wales, and Scotland reported the highest prevalence of drug use in the past 10 years. From the most recent surveys, the prevalence of any drug use in the last year was 9.4% in England and Wales, 12% in Scotland, and 5.9% in Northern Ireland. Read

7/9/20--This study tests whether nonmedical marijuana legalization predicts a higher likelihood of teen marijuana, alcohol, or cigarette use or lower perceived harm from marijuana use in a longitudinal sample of youth aged 10–20 years. Results indicated that it is important to consider recent broad declines in youth substance use when evaluating the impact of nonmedical marijuana legalization. Furthermore, states that legalize nonmedical marijuana for adults should increase resources for the prevention of underage marijuana and alcohol use. Read

7/20/20--The legalization of marijuana for Washington state adults may be thwarting a steady downward trend in teen marijuana use, according to new research from the University of Washington. The longitudinal study of more than 230 teens and young adults finds that teens may be more likely to use marijuana following legalization — with the proliferation of stores and increasing adult use of the drug — than they otherwise would have been.
