For what it's worth I have spent a great deal of time in the company of such people. Perhaps it's the case that the majority are simply living in a deluded drug-addled mist, and certainly a great many are hedonists first and last, and would be happy to admit it.
The thing is though, I see a lot of false enlightenment everywhere. There are whole swathes of people who would consider themselves spiritual for one reason or another but don't seem the least bit capable of critical thinking, open mindedness, introspection or subtlety. Ultimately, dogmatic ideology has stunted more people's personal development than drugs ever will. Not to mention the billions murdered over the centuries.
Yet in any community you will find deeply thoughtful individuals who have clearly gained and grown a great deal from their experiences and beliefs. For this reason I cannot bring myself to write any tool of potential enlightenment off, no matter what the behaviour of the average user, or if it comes in the form of scripture or white powder.
