The purpose of this 2-wave longitudinal study was to specify, test, and evaluate an actor-partner interdependence model (APIM) with young adult marital dyads to test husbands' and wives' mutual influences on each other's substance use. Prospective data were collected from young adults and their spouses at baseline and 5 years later. Data from 237 dyads were used to test spouses' interdependence on alcohol use, alcohol problems, and marijuana use with the APIMs. Marital partners had significant effects on each other's substance use, though the patterns were different contingent on the outcome referenced...

Studies investigating the impact of medical marijuana legalization have found no significant changes in adolescent use. In one of the few studies focused on recreational marijuana, we investigated how recreational marijuana legalization and community sales policy influenced factors that likely impact youth use (youth willingness and intent to use, parent use) as well as youth use. Legalization of recreational marijuana in Oregon coincided with our study on adolescent substance use. Cohort 1 transitioned from 8th to 9th grade prior to legalization and Cohort 2 made this transition during legalization (N = 444; 53% female)...

Purpose: Studies on drug use in transgender populations, particularly those in resource-limited settings, are scarce. Considering that drug use can be a coping mechanism to deal with stigma and traumatic experiences, we examined associations between stigma, trauma, and drug use in a national sample of transgender women from the Dominican Republic. Methods: Bivariate analyses examined differences between drug users and abstainers (n=287). Multivariate analyses reported odds ratios (OR) with general drug, marijuana, and cocaine use as outcomes (n=243)...

RATIONALE AND OBJECTIVES: Novel synthetic cannabinoid compounds continue to appear in the market advertised as legal alternatives to marijuana and the older synthetic cannabinoid compounds which are now controlled substances. Most of these newer compounds have been found to act at CB1 receptors, so the purpose of this study was to study the abuse liability of these compounds. METHODS: Five of these compounds (BB-22, FUB-PB-22, 5F-AMB, NM2201, and MAB-CHMINACA) were tested for their ability to produce discriminative stimulus effects similar to Δ(9)-tetrahydrocannabinol (Δ(9)-THC) in rats...

In this article, we focus on the potential influence of a scientist's advocacy position on the public's perceived credibility of scientists as a whole. Further, we examine how the scientist's solution position (information only, non-controversial, and controversial) affects the public's perception of the scientist's motivation for sharing information about specific issues (flu, marijuana, climate change, severe weather). Finally, we assess how perceived motivations mediate the relationship between solution position and credibility...

Alcohol, nicotine and cannabis are among the most commonly used drugs. A prolonged and combined use of these substances can alter normal brain wiring in different ways depending on the consumed cocktail mixture. Brain connectivity alterations and their change with time can be assessed using functional magnetic resonance imaging (fMRI) because of its spatial and temporal content. Here, we estimated dynamic functional network connectivity (dFNC) as derived from fMRI data to investigate the effects of single or combined use of alcohol, nicotine and cannabis...

Grounded in the Achievement Goal Theory framework of motivation and optimal functioning, there were two objectives of this study: (a) to test a model hypothesizing links between personal theories of school achievement, indices of the quality of academic engagement, wellbeing, and health-related behaviors, and (b) to explore whether the hypothesized model was invariant across gender groups. A multisection questionnaire pack tapping the targeted variables was administered to 967 teenagers (475 boys and 492 girls) aged between 11 to 16 years old...

BACKGROUND: Men who have sex with men (MSM) have higher rates of substance use compared to men who have sex with women. Among MSM, drug use is linked to higher-risk sexual behavior and acquisition of HIV and other sexually transmitted infections. OBJECTIVES: We hypothesize that time since first acting on one's same sex attraction, or one's "gay age", could be predictive of drug using behavior. METHODS: We examined this question among 176 MSM, aged 18-35, presenting at a public sexual health clinic...

According to the 2015 National Survey on Drug Use and Health, cannabis (marijuana) is the most commonly used recreational drug in the US. Among pregnant women aged 14-55 years, 3.4% were cannabis users. Presently, little is known about the neurodevelopmental effect of cannabis use during pregnancy and/or nursing on neonates. Endothelin (ET) is essential for normal development of the central nervous system (CNS). Decreases in ETB receptor expression correlate with a decline in nerve growth factor (NGF) and an increase in vascular endothelial growth factor (VEGF) in postnatal brain...

BACKGROUND: Some cannabinoids, a family of compounds derived from Cannabis sativa (marijuana), have previously shown vasodilator effects in several studies, a feature that makes them suitable for the generation of a potential treatment for hypertension. The mechanism underlying this vasodilator effect in arteries is still controversial. In this report, we explored how the synthetic cannabinoids ACPA (CB1-selective agonist) and JWH-133 (CB2-selective agonist) regulate the vascular tone of rat superior mesenteric arteries...

BACKGROUND: Electronic Dance Music (EDM) party attendees are often polysubstance users and are at high risk for use of new psychoactive substances (NPS). We sought to identify patterns of use of common illegal drugs among EDM party attendees, sociodemographic correlates, and use of NPS as a function of patterns of use of more common drugs to inform prevention and harm reduction. METHOD: Using time-space-sampling, 1045 individuals aged 18-40 were surveyed entering EDM parties in New York City...

This study examined whether an increase in the availability of mental health services at school-based health centers (SBHCs) in Oregon public schools was associated with the likelihood of suicidal ideation, suicide attempts and substance use behaviors among adolescents who experienced a depressive episode in the past year. The study sample included 168 Oregon public middle and high schools and 9073 students who participated in the Oregon Healthy Teens Survey (OHT) in 2013 and 2015. Twenty-five schools had an SBHC, and 14 of those schools increased availability of mental health services from 2013 to 2015...

REVIEW
T Urban, J Hureaux
Cannabis use increased sharply from 2010 to 2014 in France. Cannabis is often consumed with tobacco, although the use of marijuana is developing. Tobacco and cannabis smoke have many common characteristics in terms of irritants, carcinogens and carbon monoxide. They also differentiate by their dependence mechanisms, with nicotine and its receptors for tobacco and tetra-hydro-cannabinol (THC) and its specific receptors for cannabis. Chronic inhalation (700,000 daily users in France) over a long period most likely increases the relative risk of bronchial cancer...

BACKGROUND AND OBJECTIVES: Marijuana is the most commonly used illicit drug among college students, with heavy use leading to negative outcomes. Use of marijuana for medical and recreational purposes in select U.S. states has been controversial, with concerns surrounding increased prevalence rates and harm. The current exploratory study aimed to assess marijuana use in college students in Colorado, demographic differences in frequency of use, and motives for using. METHODS: College students (N = 300; 61% female) were recruited through introductory psychology courses and completed a series of questionnaires and a marijuana urine screen...

Purpose: Much criminal justice research has ignored racial/ethnic and gender differences in substance use subsequent to criminal justice involvement. This paper investigated how early adulthood arrest (i.e., 18 to 21 years of age) influences individuals' subsequent transitions from non-substance use to substance use, and substance use to non-substance use through age 30. We also consider if these relationships differ by race/ethnicity and gender. Processes proscribed by labeling theory subsequent to getting arrested are considered...

Cannabinoid hyperemesis syndrome (CHS) is an underrecognized diagnosis among adolescents. In the adult literature, it is characterized as nausea, vomiting, and abdominal pain in patients with chronic marijuana use. CHS is often refractory to the standard treatment of nausea and vomiting. Unconventional antiemetics, such as haloperidol, have been successful in alleviating symptoms; however, even 1 dose of haloperidol can lead to grave adverse effects, such as dystonia, extrapyramidal reactions, and neuroleptic malignant syndrome...

BACKGROUND: This study examined factors associated with marijuana use initiation among never users, prior-to-past year user who return to use, and users who continue use over a 12-month follow-up period. METHODS: Two waves (W1 and W2) of the Population Assessment of Tobacco and Health (PATH) Study provided data (N=26,204 aged 18+). Multivariable logistic regression models were used to examine associations of W1 sociodemographic, health/mental health, and other substance use characteristics with W2 use status...
