Our goal is to evaluate the extent to which problematic cannabis use research has been conducted through a sex and gender lens, and to identify areas for future research and opportunities to incorporate sex-informed and gender-responsive or -transformative interventions to prevent and treat CUDs

Justin Matheson, PhD (he/they) @justinrmatheson.com · May 13

New pilot cannabinoid RCT just dropped! We examined feasibility and preliminary efficacy of nabilone for body weight reduction in adults in obesity, and also looked for some potential mechanisms. Long story short - the drug regimen was not well tolerated

Well, folks, this is it. Today is the last day of my 4.5 year postdoc.

I'm still planning to become a PI some day, but for now, I'm doing a detour to pick up some management skills as a Research Manager in the Institute for Mental Health Policy Research at CAMH. Very grateful for this new role!

Is there a Starter pack for Spec scripts 😍

Lee Bice-Matheson @leebicematheson.bsky.social · Dec 4

Our Spec script is described as a unique blend of Indigenous spirituality & Christian ideology. Feedback: film can appeal to fans of atmospheric supernatural horror - emotional & philosophical edge, like The Others The Sixth Sense or Hereditary. Elevated genre + Spiritual depth + Family dynamics🥲🎥🎞️🎬
