Singling out the few substances people have been taking on purpose, in addition to their regular diet, to obtain certain effects, is a poor way of identifying chemicals that should be avoided because they are 'drugs'. It is simply an absurd definition of 'drugs'. You take drugs everyday, in large doses, with your regular diet. Change your diet and you change, for the better or the worse, because there are some substances you suddenly take in much more or much less. Not too mention all the stuff that's in our regular drinking water: instead of avoiding pot, I'd start by avoiding tap water.
