MONDAY, Nov. 18, 2019 (HealthDay News) — Contrary to expectations, the prevalence of cannabis use disorder (CUD) decreased significantly among individuals reporting daily\/almost daily cannabis use between 2002 and 2016, according to a study published in the Dec. 1 issue of Drug and Alcohol Dependence<\/i>.<\/p>\n
Julian Santaella-Tenorio, Dr.P.H., from Columbia University in New York City, and colleagues used data from the National Survey on Drug Use and Health (2002 to 2016) to identify 22,651 individuals using cannabis \u2265300 days in the past year. Trends in CUD were identified by age group (ages 12 to 17 years, 18 to 25 years, and \u226526 years).<\/p>\n
The researchers found that the prevalence of CUD among individuals reporting daily\/almost daily cannabis use decreased by 26.8 percent in adolescents, by 29.7 percent in those ages 18 to 25 years, and by 37.5 percent in participants \u226526 years. The prevalence of cannabis dependence (defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition<\/i> [DSM-IV]) decreased significantly among adolescents (\u221243.9 percent) and young adults (\u221226.8 percent), but it remained stable in adults \u226526 years. Among young adults, there were reductions in most dependence items, but patterns were less consistent in adolescents and adults \u226526 years. Across all age groups, the prevalence of DSM-IV cannabis abuse decreased both overall and for each abuse item.<\/p>\n
“The findings contradict the predominating hypothesis that the prevalence of DSM-IV CUD would be stable, or increase, among those using with this regularity,” a coauthor said in a statement.<\/p>\n
