Well, if by 'in right now' you mean at least 7k - 9k years you might be right [0][1]. If you believe what ethnobotanist like Terence Mckenna [2] say, then it's much older and has shaped the hominids evolution quite significantly. It seems almost all cultures found local hallucinogens and exploited them heavily for ceremony, healing etc and was strong part of who they were [3].
Anecdotally, I think hallucinogen just highlighted mental issues that were already there. I also know some really smart people who have done their share of it with no problem (that i can see). If I could go back in time, i'd do it all again. We, as humans, were pretty open about all this not too long ago. I am happy to see a small number never stopped and psychonauts [4] though not always scientific, have kept exploring and bringing back ideas and experiences for these alternate states of reality.
Tangentially, Carlos Castaneda's [5] books were some of the best i've read and would recommend it to people.
