This has nothing to do with drugs "feeling good."
There has been substantial research recently showing that in some ways that I, at least, don't yet fully understand, various different psychedelics have the ability to "reset" the brain. This appears to be an effective long-term treatment for depression and anxiety—much, much longer-term than the direct effects of the drug—the trip, or any euphoria associated with it; in some cases, on the order of months, or even, for some lucky people, permanently.
So take your "this is pretend science" and shove it. Just because you don't approve of drugs that have been deemed illegal and immoral in the past doesn't change their very real benefits to some people—or the fact that depression is not, and has never been, something that can be cured by "an all expenses paid weeklong camping trip" or any other pleasant experience. Mental illness is serious and debilitating, and if psilocybin and other psychedelics can be more effective treatments than what we have now—which very real science indicates is highly likely—then that's going to be amazing for millions of people all over the world.
You're welcome to go take your camping trip and ignore the news about it.
