Well, to be fair, nothing in life is really "harmless" anyways. Drugs like cannabis and LSD are far safer and less destructive to the body than alcohol even is, but the point isn't to take too much (like getting drunk). The effects of these drugs are comparable to something like meditation and are more likely to put you to sleep than "make you do something stupid", especially the more you take.
