Okay, lets say you're right. What does that imply about all the other things people do? Why are you watching movies - what is that a substitute for? Why are you exercising so much - what do you have to hide from yourself?

Given that you could (and should) ask these questions legitimately, why focus on recreational psychadelics? I think the answer is that you've internalized a particular cultural story about drugs, and you probably have Nancy Reagan to thank for that.

Being against mushrooms seems particularly odd, since every human being on the planet involuntarily falls unconscious and hallucinates for hours every single night, including you. In the hierarchy of damaging escapist behavior, it's pretty low I think (far lower certainly than say, Facebook or Twitter usage).
