Associations between anhedonia and marijuana use escalation across mid-adolescence.

ABSTRACT: Anhedonia-a transdiagnostic psychopathological trait indicative of inability to experience pleasure-could lead to and result from adolescent marijuana use, yet this notion has not been tested. This study aimed to estimate the association of: (1) anhedonia at age 14 with rate of change in marijuana use over an 18-month follow-up, and (2) marijuana use at age 14 with rate of change in anhedonia over follow-up. Secondary aims were to test whether gender, baseline marijuana use history and peer marijuana use moderated these associations.Observational longitudinal cohort repeated-measures design, with baseline (age 14 years), 6-month, 12-month and 18-month follow-up assessments.Ten public high schools in Los Angeles, CA, USA, 2013-15.Students [n = 3394; 53.5% female, mean (standard deviation) age at baseline = 14.1 (0.42)].Self-report level of anhedonia on the Snaith-Hamilton Pleasure Scale and frequency of marijuana use in the past 30 days.Parallel process latent growth curve models adjusting for confounders showed that baseline anhedonia level was associated positively with the rate of increase in marijuana use frequency across follow-ups [?, 95% confidence interval (CI) = 0.115 (0.022, 0.252), P = 0.03]. Baseline marijuana use frequency was not related significantly to the rate of change in anhedonia across follow-ups [?, 95% CI = -0.015 (-0.350, 0.321), P = 0.93]. The association of baseline anhedonia with faster marijuana use escalation was amplified among adolescents with (versus without) friends who used marijuana at baseline [?, 95% CI = 0.179 (0.043, 0.334) versus 0.064 (-0.071, 0.187), interaction P = 0.04], but did not differ by gender or baseline ever marijuana use.In mid-adolescence, anhedonia is associated with subsequent marijuana use escalation, but marijuana use escalation does not appear to be associated with subsequent anhedonia.

Project description:Background:Polytobacco product use is suspected to be common, dynamic across time, and increase risk for adverse behavioral outcomes. We statistically modeled characteristic types of polytobacco use trajectories during mid-adolescence and tested their prospective association with substance use and mental health problems. Methods:Adolescents (N = 3393) in Los Angeles, CA, were surveyed semiannually from 9th to 11th grade. Past 6-month combustible cigarette, e-cigarette, or hookah use (yes/no) over four assessments were analyzed using parallel growth mixture modeling to identify a parsimonious set of polytobacco use trajectories. A tobacco product use trajectory group was used to predict substance use and mental health at the fifth assessment. Results:Three profiles were identified: (1) tobacco nonusers (N = 2291, 67.5%) with the lowest use prevalence (<3%) of all products across all timepoints; (2) polyproduct users (N = 920, 27.1%) with moderate use prevalence of each product (8-35%) that escalated for combustible cigarettes but decreased for e-cigarettes and hookah across time; and (3) chronic polyproduct users (N = 182, 5.4%) with high prevalence of each product use (38-86%) that escalated for combustible cigarettes and e-cigarettes. Nonusers, polyproduct users, and chronic polyproduct users reported successively higher alcohol, marijuana, and illicit drug use and ADHD at the final follow-up, respectively. Both tobacco using groups (vs. nonusers) reported greater odds of depression and anxiety at the final follow-up but did not differ from each other. Conclusions:Adolescent polytobacco use may involve a common moderate risk trajectory and a less common high-risk chronic trajectory. Both trajectories predict substance use and mental health symptomology. Implications:Variation in use and co-use of combustible cigarette, e-cigarette, and hookah use in mid-adolescence can be parsimoniously characterized by a small set common trajectory profiles in which polyproduct use are predominant patterns of tobacco product use, which predict adverse behavioral outcomes. Prevention and policy addressing polytobacco use (relative to single product use) may be optimal tobacco control strategies for youth, which may in turn prevent other forms of substance use and mental health problems.

Project description:Background:Adolescence has been identified as a critical risk period for substance use initiation, such as marijuana. Although several factors have been cited for adolescent marijuana use, those that influence initiation, especially in an African setting where illicit marijuana activities are rife, have not been contextually explored. Aim:We ascertained the factors that influence adolescent marijuana use initiation in two marijuana-growing communities in the Eastern Cape province of South Africa, based on the constructs of the socio-ecological model. Setting:The study was conducted in two selected illicit marijuana growing communities in the Ingquza Hill Local Municipality of the Eastern Cape province of South Africa. Methods:Focus group discussions (FGDs) were conducted among 37 participants, grouped into four focus groups. Purposive and snowball sampling techniques were used to select the communities and participants, respectively. An FGD guide was used to collect the data. The data were analysed using thematic content analysis approach and presented under various themes. Results:Twelve influences of adolescent marijuana use initiation, grouped under three main levels of socio-ecological influence, personal characteristics (curiosity, shyness and fulfilment of personal need), micro-level influences (peer pressure, negative school climate, presence of marijuana in households and parental or sibling marijuana use) and macro-level influences (child labour, poverty, presence of marijuana in communities, presence of negative adult role models and breakdown in communal restrictions against marijuana use), were found. Conclusion:Health promotion programmes, targeting socio-ecological motives of adolescent marijuana use initiation in the two communities, should be intensified to break the cycle of adolescent marijuana use. Also, alternative livelihood schemes should be implemented in the affected communities to break the cycle of illegal marijuana cultivation that promotes adolescent marijuana use.
