Traditional medicine includes psychoactive plants in many cultures. Forget the Greeks they were new comers. There is evidence psychoactive mushrooms were consumed for perhaps tens of thousands of years, cannabis as well, opium poppies, khat, coca leaf etc. Does not mean people just sat around getting shit faced all day. There was a purpose to the use of these substances, usually spiritual. Etoh or ethanol alcohol is a fairly new development and was derived during the transition from hunter/gatherer or nomadic lifestyles to that of a more urban society. Plenty of literature out there all one needs to do is use the internet to search for things other than Bluelight. IDK just my 5 cents. You could even study stuff at uni whoa!!
