No, MISUSE of psychoactive drugs is bad.
There is a strong basis for the psychoactive compounds found in weed to have valid and greatly needed therapeutic properties for a wide range of conditions.
Just a small sampling of conditions that can be helped by said compounds:
EpilepsyAlzheimer's dementiaDepressionSome forms of AnxietySaying "The WEED is bad, M'kay!" is absurdity. Abusing *ANYTHING* is bad. Not just weed.
The deal is, there are people with a vested interest in asserting straight up that THC, its analogues, and its derivatives are always 100% bad, because they are either idiots that bought into the reefer madness bullshit, or because they are involved in the revolving merry-go-round of the DEA, or have pharmaceutical products they want to push instead.
By definition, we have conclusively proven that THC is not schedule I, because it has legitimate medical benefit. We just have a very profitable prison industry that is sustained by marijuana use as its bread and butter crime to keep its prisons packed with people. /rant
Edit--
And if you want a real kicker--- The evidence in favor of benefits to treating anxiety and depression can be taken with the alarming
statistics for anxiety and depression in US citizens-- (nearly 18% of US citizens suffer from an anxiety disorder, of which only 37% get treatment) coupled with the
obscene incarceration rate for marijuana possession and a surprising case could be made that public health would IMPROVE by legalizing weed for recreational use, as more people at risk for anxiety and depression would self-medicate via recreational use without realizing, and significant portions of the population would no longer be institutionalized for profit.
