I've seen it many times in posts relating to health, drug use or alcohol: a tendency to piss all over alcohol in particular (cigarettes as a close second) and those who use anything more than a tiny amount of it while hardly blinking at descriptions by others describing THC, LSD, MDMA and all sorts of other ad hoc mind altering drug mixes as a solution to assorted psychological situations. Many people here regularly describe consuming large amounts of THC in different forms, get applauded by others who do the same and then strongly criticize the notion of someone drinking more than some very moderate, arbitrarily defined amount of alcohol per week or X time frame.

In the absence of concrete evidence showing explicitly why your drug of choice is superior to someone else drug of choice, it's hypocritical to shit on their preferences as moral weakness while you happily indulge your own substances.
