Uruguay legalised marihuana, more than that, the state produces it. Holland tolerates the selling of weed and 'smart' drugs. In the u.s. some states have legalised marihuana as well. Canada has taken over Hollands coffeeshop example. There is a political current finally breaking the old prejudices against drugs and seeing them for what they really are about: individual choice and public health. Criminalization only worsens the problem. Nobody gets better from a prison sentence for taking the decision of getting high or selling somebody his high. A transaction based on mutual consent and to the benefit of both parties involved. Now we know politicians think of their voters last (the ones who didnt contribute millions to their campaign) but when they finally decriminalize drug use, will darknet markets lose their reason for existence?
The days psychedelics get legal, there will be a huge backlash from conservatives from across the political spectrum.
LSD/Psilocybin/DMT/Mesca etc, imo, permanently erode socially indoctrinated values in most users. Most psychedelic users won't buy into government propaganda, would demand greater freedoms - and a lot of things society imo is simply not ready for.
Eventually these things would be legal and freely available, but not anytime soon.
All modern civilizations, at various points, moved away from psychedelic use (since there is evidence that ancient cultures used copious amounts). Ever since they have been re-discovered, there has been a constant clash. The first big clash was during the counter culture days.
The internet has fueled more psychedelic use than ever in recent history. It is impossible to eliminate all psychedelics. You can control LSD precursors, but what about RCs? What about shrooms or DMT?
The second big clash is coming, and it will be interesting to see how an existing social structure can defend itself from something which is super attractive, but questions the very premises the existing order is based on.
