I don’t have any doubt drugs are harmful it’s just physically impossible to OD on LSD. A large lab animal, a steer I believe, was given a dose equal to several thousand times the typical human dose and simply went to sleep. It’s not good for you and may well be psychologically harmful but does not appear to be particularly harmful physically.
