A lot of sibling comments here questioning the parent comment's definition of detrimental. Psychedelic drugs can absolutely have a permanent detrimental effect on people.
There is a difference between a positive emotional experience and a warped "revelation" that gives somebody the impression that they're privy to some universal truth or meaning. If the latter happens enough, the results range from the person being pretty fundamentally changed (less like depressed vs. not depressed, more like somebody is wearing a skinsuit of somebody you used to know) to them being almost completely fried/detached from reality. These people may be happy in their own reality, but it's very painful to watch it happen to them.
Headlines like this article's are best left unsaid. A single (or rarely administered) 10-25mg dose in a highly controlled environment may be reasonably safe, and the headline may be true in the strictest sense, but it's going to work out about as well as the "marijuana is not addictive" line of thinking has.
I think you articulated my point much better. The spiritual effect I was describing is definitely also:
"to them being almost completely fried/detached from reality"
What these researchers are doing in a lab on well adjusted humans with no psychedelic experience, and what happens when people take doses recreationally are two completely different things. Its like doing cocaine one time with a small dose and claiming it has no negative effects.
