About

This study is a critically important first-of-its-kind investigation of the potential research utility of using contingency management to examine long-term changes in cannabis use with six months of abstinence. These pilot data will inform a later trial which will focus on testing the longitudinal relationships between adolescent cognition and cannabis use, questions of high and growing public health significance given adolescents' increased access to cannabis with legalization.
