In the latest edition of “what we’ve been saying all along,” a study by researchers from the University of Ottawa found that individuals who visited the ER due to marijuana use are 14.6 times more likely to develop schizophrenia. And here’s the big one: individuals who visited the ER due to cannabis-induced psychosis are a dizzying 241.6 times more likely to develop schizophrenia. No, that’s not a typo. What’s driving this? The potency of marijuana has skyrocketed. Far from Woodstock weed, there has been a sizable jump in potency since the 2000’s alone. Two decades ago, average marijuana potency was about 4% THC. Now? Over 20%. This fivefold increase in potency has, predictably, led to a public health disaster. Weed makes you lose your mind. Sometimes for good.
