My friend is also have difficulty leaving the path. A couple of months ago my buddy & I got some urgent texts from him-- he had taken a really large dose of LSD and ended up spending the next 12 hours in a emergency room's psych ward.
I think that part of the reason that we have this B.S. propaganda around psychedelics (i.e. "They're the key to enlightenment!") is that it can be pretty hard to encourage people to try drugs. And while they aren't the key to enlightenment, they are just such a _different_ experience that it can be... interesting, or help personal growth, in some lesser but still substantial ways. But that's not a great soundbite.
Marketing is much harder than we give it credit for.
//edit although on further googling, I think the quote is from Alan Watts and it's about sober meditation after a trip.
> "Psychedelic experience is only a glimpse of genuine mystical insight, but a glimpse which can be matured and deepened by the various ways of meditation in which drugs are no longer necessary or useful. If you get the message, hang up the phone. For psychedelic drugs are simply instruments, like microscopes, telescopes, and telephones. The biologist does not sit with eye permanently glued to the microscope, he goes away and works on what he has seen..."
