There is another common party trick of using chemical substances such as LSD or psilocybin to alter perception and thought processes.

For some people, this trick leads them to believe that the universe is full of messages from beyond; or that people who have used this trick are epistemically superior to those who haven't; or other spiritual beliefs. For other people, this trick leads them to believe that the mind — yes, the very mind you are, thinking these very thoughts — runs on chemistry, and so of course can be altered with chemistry.

Some people freak out. Others grin a lot and say it's cool.
