A new study published in the journal Substance Use & Misuse suggests neither occasional nor heavy marijuana use by adolescents decreases motivation. Researchers from the Florida International University looked at cannabis use and motivation in 79 adolescents who were both long-term regular and occasional users. The investigators looked at motivational tendencies using the Apathy Evaluation Scale and the Motivation and Engagement scale, and found, “After controlling for confounds, no significant differences were observed between regular and light users on any motivation index. Similarly, no associations between motivation and lifetime or past 30-day cannabis use amount were observed… Our findings do not support a link between reduced motivation and CU among adolescents after controlling for relevant confounds.”
