Study: Cannabis Use Does Not Reduce Motivation in Adolescents

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.”

    To be straight up, I personally feel like some strains have a negative impact on motivation whereas others are the exact opposite. I mean, some of them are like “couch-lock munchy mode 9000” and others are like “LET’S BE SOCIAL AND DO THINGS!” Right? Guess I should probably take a look at the study and see exactly how they conducted it because this seems to be too much of a universal conclusion when not all strains are created equal and their effects are similarly unequivalent.

    This is reliable. Even studies prove that Cannabis is safe to use even for adolescents.
