Why This Matters
Scientists have proven that cannabis-triggered appetite is a real brain response—not just a stereotype—which could lead to life-saving treatments for patients with HIV/AIDS and cancer who can’t eat.
Clinical Summary

Psychology Today analysis examines the tension between cannabis legalization and emerging mental health research. THC potency has risen dramatically since the 1990s, with vape cartridges now near-pure levels. A large European multi-site study found daily high-potency cannabis use correlated with increased odds of psychotic disorders. Adolescents who used cannabis showed increased risk of psychotic symptoms later in life. The article argues legalization may require stricter potency controls and better public education, as framing cannabis as completely harmless prevents accurate risk assessment—especially for youth who equate legality with safety.

Dr. Caplan’s Take
“The munchies just went from cultural punchline to clinical roadmap: if we can harness this brain mechanism, we may be able to help wasting syndrome patients without requiring them to get high.”
Clinical Perspective

WHEN LEGALIZATION MEETS REALITY: THE POTENCY PROBLEM

Psychology Today published an important analysis that cannabis advocates need to reckon with honestly. High-THC cannabis is linked to higher psychosis risk, particularly for young, heavy users. THC potency has risen dramatically since the 1990s, with vape cartridges reaching near-pure levels. A large European study found daily high-potency use correlated with increased psychotic disorders. Adolescent users face elevated risk later in life.

The responsible position isn’t pro-cannabis or anti-cannabis. It’s pro-evidence. We need potency-tiered regulation, mandatory public health education funded by cannabis tax revenue, and restrictions on high-potency products. Legalization without education is half a policy.
