The Truth is that, we do KNOW that it has medicinal properties!
However, it is the quantity and the exaggeration of its use that does become then recreational and not medicinal.
The world seems scared of it, thinking that the whole population will use it?!
While people may try it, that doesn't mean subsequently they will become hooked.
Alcohol and tobacco are more adictive and destructive (on exaggeration) than MaryJuana is.
Quite frankly, i would rather have people use this herb than harcore drugs that are destructive.
