A preliminary test of a brief intervention to lessen young adults' cannabis use: Episode-level smartphone data highlights the role of protective behavioral strategies and exercise.

Brief interventions are increasingly being used to help young adults to moderate their cannabis use. We conducted a randomized clinical trial of a brief (4 weekly sessions), in-person intervention that included a smartphone application that reinforced the use of protective behavioral strategies (PBSs) to lessen cannabis use. Young adults ( = 37; 24 men) who regularly used cannabis were randomized to 2 intervention conditions rooted in cognitive-behavioral therapy (CBT) and motivational enhancement therapy (MET).

Effects of exercise on experimentally manipulated craving for cannabis: A preliminary study.

Cannabis is the most commonly used illicit drug in the United States, and craving for cannabis is related to cannabis use. Exercise has been demonstrated to reduce craving for substances. To examine the effects of exercise on cannabis craving, we conducted a 3-week within-subject crossover experiment.
