Despite the fact that cannabinoids have been studied for their potential as antihypertensive agents since the 1970s, no cannabinoid-based medications have been officially approved to treat hypertension. Moreover, despite an ever-growing body of anecdotal evidence and numerous studies suggesting the regular use of cannabis does appear to produce long-term lower blood pressure levels, we lack the sort of rigorous human studies that would allow physicians to confidently say, “Use cannabis to treat your hypertension!”
A Harvard Medical School study concluded that for an hour after consuming cannabis (especially in at-risk populations; e.g. seniors), the odds of suffering a heart attack increases by five times. Risk returns to normal within two hours. Notably, sex carries a comparable risk increase.
