Trendy drug taking

So, someone at Vox writes about his ayahuasca taking retreat at Costa Rica.

It sounds like a rather expensive, New Age-y sort of place, with 4 nights of drug taking, with lots of crying (and puking) and apparent insight which nonetheless seems to have worn off after a few weeks back in normal land.

I remain unconvinced that the benefits some people feel from the experience are worth it.   While open to the idea that people with certain specific psychological issues might benefit from controlled usage of certain psychedelics, my overall impression is the experiences usually give an emotional insight that is later seen as a false dawn.
