Everything I see labeled that way, psychedelics included, has a reputation of being either a cause of loss of self-control or a consequence of lacking self-control.
If you want to be in the habit of understanding people who use words like that to describe others keeping that frame in mind may make their fears, and emotional reactions easier to understand, even when you disagree with their premise or judgements.
(edit: fix a few typos)
edit: to respond to greyface- below since I am not longer allowed to reply. what you seem to be hinting at amounts to reasoning by extremes, a trite fallacy.
Please define "degenerate". Would you consider individuals who hold successful, stable careers (they may even hold down a high-level role), have a family, no criminal records, for all intents and purposes are 'normal' people, but maybe once every few years they go camping with friends and consume psychedelics, to be a "degenerate"?
Because to me it sounds like you're making a gigantic blanket generalization.
The word "degenerate" is reasoning by extremes. It signals puritanical zealotry from a palingenetic perspective.
Whatever glorious past you think society is de-generating from is a myth composed by people with rosy-eyed memories and an agenda that, were it not for the justifying myth, would be obviously absurd.
Referring back up to the earlier comments, what I read here strikes me as similar to the opinions the earlier commenter was describing, the idea that the success of society relies on some inherent concepts of self-control and personal sovereignty that are somehow threatened by use of psychedelic drugs. You are completely entitled to your own opinion, but throwing the d-word around isn't doing anything to clarify why you hold that opinion for me. It reads like an argument based on emotion.
