Psilocybin

Alcohol and tobacco, which you are free to legally consume as you should be, are HIGHLY addictive substances and are responsible for millions of deaths to date. Yet psilocybin, a substance that literally enables parts of your brain to communicate that otherwise could not, is well tolerated by our bodies as well as being non-addictive, is considered 'dangerous' by the U.S. government, and its use can land you in prison.

This is a messed up world we live in.
