HealthDay News — According to a study published in The Annals of Family Medicine, a brief intervention conducted by general practitioners could reduce cannabis use among some younger users.

Catherine Laporte, MD, PhD, from the University Clermont in France, and colleagues conducted a cluster randomized trial involving 77 general practitioners in France to test the efficacy of a brief intervention among cannabis users aged 15 to 25 years. 

The intervention comprised an interview designed according to the feedback, responsibility, advice, menu, empathy, self-efficacy model, while the control condition was routine care.

Two hundred sixty-one young cannabis users were screened and followed. The researchers found that among all users there was no significant between-group difference in the median number of joints smoked per month after one year (17.5 versus 17.5; P=.13); however, among non-daily users there was a difference in favor of the intervention (3.0 versus 10.0; P=.01).

In terms of the number of joints smoked, the intervention correlated with a more favorable change from baseline after six months (−33.3 versus 0%; P=.01). The intervention correlated with smoking of fewer joints per month among users younger than 18 years (12.5 versus 20.0; P=.04).

“Our results do, however, strongly support use of brief interventions for users who are younger than age 18 and for moderate, non-daily users,” the authors write.
