Back in the 70s & 80s when I was in favor of legalizing weed, it was low potency stuff.
Nowadays, the weed is many, many times more potent. And, IMO, it’s creating a mental health crisis. Take a look at this Yale Med School Fact Sheet on Cannabis & Psychosis—
https://medicine.yale.edu/psychiatry/step/resources/Cannabis%20Use%20and%20Psychosis_380524_284_47327_v2.pdf
If exposed to cannabis in adolescence, research shows individuals are 2-4x more likely to develop a schizophrenia spectrum disorder, than if you were not exposed
Frequency and amount, time of exposure, duration of exposure, and potency of cannabis all impact amount of risk for psychosis associated with cannabis use (greater frequency and duration, earlier first use, and higher potency THC = greater risk of psychosis)
Daily and higher potency cannabis leads to increased risk of psychosis
Today’s cannabis tends to be more potent (higher levels of THC) than several decades ago
15% of new cases of psychosis are attributable to cannabis use
I’m not saying one puff and you go crazy. I am saying there is a vulnerable population (those at risk of developing schizophrenia) and, per Yale Med, weed raises their risk of developing schizophrenia and ruining their lives.
