When considering medical marijuana therapy for their children, parents may be concerned about the side effects marijuana has on adolescent brain development and behaviors. Now, a study conducted by a team of researchers from Florida International University could ease these fears. In the study, which was published in the journal Substance Use & Misuse, researchers looked at the relationship between cannabis use and motivation among 79 adolescent subjects who were either long-term regular cannabis consumers or occasional users. They then looked at motivational tendencies using the Apathy Evaluation Scale and the Motivation and Engagement Scale, and found neither occasional nor heavy marijuana use was linked with a decrease in motivation.

The authors concluded, “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 (cannabis use) among adolescents after controlling for relevant confounds.”
