Cannabis use, even on a regular basis, does not reduce motivation in adolescents, according to a new study published by the journal Substance Use & Misuse and published online by the National Institute of Health.
For the study, researchers examined 79 adolescents ages 14 to 18, who were “classified as recent regular cannabis users (36) or light users (43).” Frequency and amount of substance use “were assessed across participants’ lifetime and during the past 30 days”, and motivation was measured “through the Apathy Evaluation Scale and Motivation and Engagement Scale.” To examine associations between cannabis use (CU) and motivation indices, researchers conducted a series of two-step hierarchical multiple regressions.
After controlling for confounds, “no significant differences were observed between regular and light users on any motivation index”, states the study. Similarly, “no associations between motivation and lifetime or past 30-day CU amount were observed”.
The study concludes by stating; “Our findings do not support a link between reduced motivation and CU among adolescents after controlling for relevant confounds.”
