Marijuana use and service utilization among adolescents 7 years post substance use treatment.

ABSTRACT: BACKGROUND:In an environment of increasingly liberal attitudes towards marijuana use and legalization, little is known about long-term trajectories of marijuana use among clinical samples of adolescents, and how these trajectories relate to health services utilization over time. METHODS:Latent growth curve analysis was used to identify distinct trajectories of marijuana use in a clinical sample of adolescents (N=391) over 7 years post substance use treatment in an integrated health system. We examined psychiatric problems and polysubstance use associated with the identified trajectory groups using general linear models. Nonlinear mixed-effects logistic regressions were used to examine associations between health services use and the trajectory groups. RESULTS:We identified three marijuana use trajectory groups: (1) Abstinent (n=117); (2) Low/Stable use (n=174); and (3) Increasing use (n=100). Average externalizing and anxiety/depression scores were significantly lower over time for the Abstinent group compared to the Increasing and Low/Stable groups. The Low Stable and the Increasing group had fewer psychiatric visits over time (p<0.05) and the Low/Stable group used more substance use treatment services over time compared with the Abstinent group (p<0.001). CONCLUSIONS:Treated adolescents showed distinct marijuana use patterns, one of which indicated a group of adolescents at risk of increased use over time. These individuals have greater psychiatric and polysubstance use over time, but may not be accessing needed services.

Project description:OBJECTIVE:Despite the known association between substance use disorders and major depressive disorder (MDD) among adolescents, little is known regarding substance use among adolescents with MDD. METHOD:Youths with MDD who had not improved after an adequate selective serotonin reuptake inhibitor trial (N = 334) were enrolled in the Treatment of SSRI-Resistant Depression in Adolescents trial. Analyses examined substance use (via the Drug Use Severity Index) and changes therein in relation to treatment and depressive symptoms. Adolescents meeting substance use disorder criteria via the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version at baseline were excluded. RESULTS:Substance use was common: 28.1% reported repeated experimentation at baseline. Substance-related impairment was associated with baseline depression severity, older age, physical/sexual abuse, family conflict, hopelessness, and comorbid oppositional defiant disorder/conduct disorder. There was significant improvement in substance-related impairment among adolescents who responded to MDD treatment. Baseline suicidal ideation was higher among the subjects who progressed to high substance-related impairment (? 75th percentile) versus those whose substance-related impairment remained low (< 75th percentile), and parental depressive symptoms predicted persistence of high substance-related impairment during the study. The MDD response was best among the adolescents with low 12 week substance-related impairment scores regardless of whether they had high or low baseline substance-related impairment. There were no significant differential effects of specific treatments, pharmacological or cognitive-behavioral therapy, on substance use. CONCLUSIONS:Substance use is common among adolescents with treatment-resistant MDD. The subjects who had persistently low substance-related impairment or who demonstrated reduced substance-related impairment had better MDD treatment response, although the direction of this association is uncertain.

Project description:Background and aimsBetween 2002 and 2014, past-month marijuana use among pregnant women in the United States increased 62%, nearly twice the growth of the general population. This growth coincides with the proliferation of state medical marijuana laws (MMLs) authorizing physicians to recommend marijuana for approved conditions. We estimated the association between MMLs and substance use treatment utilization among pregnant and non-pregnant women of reproductive age. We also examined whether the association varied across MML provisions, age groups and treatment referral sources to clarify potential pathways.DesignNation-wide administrative data from the 2002-14 Treatment Episodes Data Set Admissions, and a difference-in-differences design that exploited the staggered implementation of MMLs to compare changes in outcomes before and after implementation between MML and non-MML states.SettingTwenty-one MML and 27 non-MML US states.ParticipantsPregnant and non-pregnant women aged 12-49 admitted to publicly funded specialty substance use treatment facilities.MeasurementsThe primary outcome variable was the number of treatment admissions per 100 000 women aged 12-49, aggregated at the state-year level (n = 606). Admissions for marijuana, alcohol, cocaine and opioids were considered. The primary independent variable was an indicator of MML implementation in a state.FindingsAmong pregnant women, the rate of marijuana treatment admissions increased by 4.69 [95% confidence interval (CI) = 1.32, 8.06] in MML states relative to non-MML states. This growth was accompanied by increases in treatment admissions involving alcohol (β = 3.19; 95% CI = 0.97, 5.410 and cocaine (β = 2.56; 95% CI = 0.34, 4.79), was specific to adults (β = 5.50; 95% CI = 1.52, 9.47) and was largest in states granting legal protection for marijuana dispensaries (β = 6.37; 95% CI = -0.97, 13.70). There was no statistically significant association between MMLs and treatment admissions by non-pregnant women.ConclusionsMedical marijuana law implementation in US states has been associated with greater substance use treatment utilization by pregnant adult women, especially in states with legally protected dispensaries.

Project description:BackgroundPeople who use drugs (PWUD) often have complex health and social support needs related to substance use, yet face numerous barriers to service access, resulting in unmet treatment needs and a corresponding gap in treatment. While initiatives to scale up substance use services for PWUD in Canada - and Ontario - have been undertaken, these have excluded PWUD' perspectives, and their needs have largely been defined by other actors. As end-users of services, PWUD' perspectives are vital to understanding what services are required, and whether existent services are adequate, appropriate and effective. Thus, the present study aimed to elicit in-depth knowledge from PWUD with lived experience of accessing services to better understand their unmet treatment and service needs, towards closing the service and treatment gap in Ontario.MethodsThis qualitative study included one-on-one interviews conducted with a cohort of n = 45 adult PWUD with substance use and treatment experience in Ontario, Canada. Participants were recruited from substance use services based on ConnexOntario's directory of all provincial addiction services, as well as by word-of-mouth. Questions focused on participants' experiences and perspectives on substance use services towards understanding their service needs. Data underwent an inductive thematic analysis based on key themes that emerged.ResultsParticipants commonly engaged in polysubstance use, and identified a number of unmet substance use service needs including complex factors within the current service system that influenced access to available programs. Specifically, participants suggested the need to address stigmatization and system fragmentation, increase service provision and capacity, and scale up specific services and related supports such as harm reduction, counseling, treatment, and housing.ConclusionsThis study identified PWUD' needs in relation to substance use service provision in Ontario, Canada, and highlighted important areas for policy change and program planning and implementation. Concrete recommendations include the development of a government-funded, low-barrier, comprehensive and integrated service delivery and referral models that include PWUD as collaborators and program facilitators to ensure that services are as accessible, effective, and cohesive as possible. Results from this study can be used to enhance provincial substance use treatment and service provision.
