Living in Colorado, we were able to juice the leaves of marijuana plants for a while -- the growers only cared about the buds, and would get rid of the rest of the plant. All sorts of anti-cancer, anti-aging properties. It completely removed the fine lines I was starting to develop around my eyes. And as long as you use a masticating juicer, not a spinning juicer, it's not at all psychotropic. Sadly, either they discovered people would pay big bucks for the leaves, or the state cracked down on them, because we can't get any anymore.
