• ? Teen [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) was associated with roughly 2x the risk of developing psychotic disorders

• ? Genetic predisposition and frequency of use likely play major roles

• ⚠️ The adolescent brain is still developing well into the mid-20s

• ? [Medical cannabis](https://cedclinic.com/therapeutic-benefits-of-thc/) programs screen for psychiatric risk factors for exactly this reason

• ✅ This is not about fear — it’s about informed, age-appropriate decisionsCannabis can be powerful medicine for adults under proper guidance. But for teens, the risk-benefit equation is very different.Talk to your kids. Talk to your doctor. Knowledge is [harm reduction](https://cedclinic.com/can-you-mix-weed-and-alcohol/).
Clinical Summary

New study links teen [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) to doubled psychosis risk. This is why age, dose, and clinical oversight matter. The developing brain deserves protection, not experimentation. #CannabisSafety #MentalHealth #CannabisResearch

Clinical Perspective

New research suggests teen cannabis use may double the risk of developing psychosis. As a physician who has treated over 30,000 cannabis patients, I can tell you this tracks with what we see clinically – the adolescent brain is simply not ready for unsupervised THC exposure. This is why proper screening, age-appropriate guidance, and honest conversations with young people matter more than ever.
