resistance exercise and cannabis use

Conditions: Cannabis Use Disorder

Summary: cannabis is the most widely used illicit drug and rates of hazardous use, and cannabis use disorders (cuds), have continued to rise in recent years. the highest rates of use and cuds are seen in young adults (20 - 24 years old) with more than 50% of young adults reporting lifetime use of cannabis, 35% report use in the past year, and 20% report use in the past month. increased exposure produces higher risk for detrimental psychological and behavioral effects of cannabis use. given this increased prevalence of cannabis use and associated risks, identifying effective behavioral strategies that reduce cannabis craving, negative psychological effects, and alter neurobiological mechanisms underlying problematic cannabis use are an avenue of needed research. exercise, particularly resistance exercise, is a behavioral intervention with considerable potential as an adjunctive treatment for cud.
