Neurocognitive outcomes in adolescents with and without four weeks of cannabis abstinence: a randomized clinical trial using contingency management.

ABSTRACT:

Background

As adolescent cannabis use becomes more common, questions remain about the potential for neurocognitive recovery after stopping cannabis use.

Method

This study examined whether short-term abstinence from cannabis leads to cognitive improvements. A total of 238 adolescents (ages 13-19; 51% female; 55% White, 18% Black, 9% Asian, 18% other races) from Greater Boston participated, including 154 adolescents who regularly used cannabis (CB) and 84 adolescents with no cannabis use (NU). Participants who used cannabis were randomized to incentivized abstinence (CB-Abst) or a non-contingent monitoring control (CB-Mon). Non-users completed four weeks of monitoring (NU). Participants completed tests of executive function, memory, and attention weekly for four weeks.
