“…Cannabis users often use alcohol and tobacco (Pacifci et al, 2003; Richter et al, 2016), and association of health outcomes with cannabis use often disappear after controlling for alcohol and tobacco use (Rooke et al, 2013). Thus, the present study takes into consideration these potential confounds in the examination of association between cannabis use reduction and changes in anxiety, depression, sleep quality, and quality of life.…”

Aims This study examined the longitudinal association between reductions in cannabis use and changes in anxiety, depression, sleep quality, and quality of life. Methods Secondary analyses were conducted based on data from a cannabis use disorder medication trial in 302 adults (ages 18–50). Changes in symptoms of anxiety and depression, sleep quality, and quality of life were assessed in relation to changes in cannabis use during the 12-week trial of treatment. Results Based on the slope of individual cannabis use trajectory, the sample was classified into two groups (Cannabis Use Reduction, n=152 vs. Cannabis Use Increase, n=150) which was included as a binary covariate in subsequent modeling. Controlling for demographics (age, gender, race/ethnicity), treatment condition, and time-varying tobacco and alcohol use, separate latent growth curve models showed a significant association between the Cannabis Use Reduction group and improvement (i.e., lower values in slope) in anxiety (β= −.09, SE=0.04; p<0.05), depression (β= −0.11, SE=0.04; p<0.01), and sleep quality (β= −0.07, SE=0.03; p<0.05) over the observation period, but not in quality of life. Conclusions These results indicate a longitudinal relationship between reductions in cannabis use and improvements in anxiety, depression, and sleep quality. Clinicians treating patients with co-occurring cannabis use and problems with anxiety, depression, or sleep quality should attend to cannabis use reduction as a component of treatment.

“…Nonetheless, it is clear that both marijuana use and cannabis use disorder (CUD) has increased among young adults since the early 2000s (Caulkins et al, 2015; Grucza et al, 2016; Hasin et al, 2015; Schulenberg et al, 2017). Recent national data indicate that more than half (54%) of U.S. youth have initiated marijuana use by age 21 (Chen et al, 2017), and among past 30-day marijuana users, about one in five young adults (21– 22%) meets diagnostic criteria for CUD (Richter et al, 2016). Further, a study of 1,573 youth aged 12 to 18 attending a primary care appointment in either California or Pennsylvania found prevalence rates of marijuana use that approached those of alcohol use (past year use: 37% vs. 42%, respectively; past year heavy use: 19% vs. 22%, respectively) (D’Amico et al, 2016a).…”

Background: This study compared young adults with and without a medical marijuana (MM) recommendation from a provider (“MM card”) on their developmental trajectories of frequent marijuana use and marijuana-related problems in young adulthood. Methods: The analytic sample consists of young adult past month marijuana users (N=671) who were part of a larger, diverse, and predominantly California cohort. Analyses are based on data from seven surveys completed from ages 13–19. Results: At age 19, 28% of participants reported having an MM card to legally purchase marijuana from an MM dispensary. A multiple group latent growth model, indicated that young adults who had an MM card showed steeper increases in frequent marijuana use (i.e., 20–30 days of use in the past month) from ages 13–19 compared to young adults who did not have an MM card. Logistic regression models that matched MM card and non-MM cardholders on individual sociodemographic characteristics found that MM cardholders were more likely to report marijuana negative consequences, selling marijuana/hashish, and driving under the influence of marijuana in the past year. In addition, MM cardholders were more likely to have tried cutting down or quitting in the past 3-months. Conclusions: Among young adult marijuana users, those with an MM card had a higher risk profile for marijuana use and related problems compared to those without an MM card. Given expanding state legalization of MM, this issue warrants further attention.

“…Though estimates vary, several studies have suggested that approximately 8-10% of individuals who have experimented with cannabis at least once in their lifetime develop CUD (Anthony 2006; Lopez-Quintero et al 2011; Wagner and Anthony 2002). Estimates from a more recent, nationally representative survey in the U.S. suggest that the conversion rate to CUD may not be as high for those with lifetime cannabis use (3.5%), but higher among past year users as an estimated 11.6% met criteria for CUD (Richter et al 2017). The rate of conversion from initiation to CUD appears to be higher among adolescents relative to adults.…”

“…For instance, in a study completed in New Zealand, approximately 22% of adolescents who initiated cannabis use by age 16 met criteria for CUD by 21 (Fergusson et al, 2003). In a similar study in the U.S., individuals who began using cannabis before age 15, developed CUD more than twice as often as those who began using cannabis at age 15 or older (Richter et al 2017).…”

An increasing proportion of the world has legalized cannabis for medicinal or recreational use. The legalization trend appears to be continuing. These changes in the legislative landscape may have important health, treatment, and research implications. This review discusses public health outcomes that may be impacted by increases in cannabis availability and use. It additionally considers potential research and treatment priorities in the face of widespread cannabis legalization.
