I agree with the grandparent that there wouldn't be more informed use. However if the legal purveyors are allowed to market these substances in the same profit-motivated manner in which they currently move products (including dangerous and addictive existing legal products) then I agree we likely would see more use. Since basic common sense policy that should lead to a safer and freer world is being pragmatically limited by this profit-driven system perhaps it would pay to examine that other problem as well.
