Just do it if you're curious. You will need a safe, familiar environment and the company of at least one cool and responsible person who isn't on the trip. A known dose of acid would be the best choice (from a sheet that someone has tried). Stay indoors. Don't go to a movie, or rock concert, don't answer the phone. Give yourself 12 hours for the trip, and a day of recovery afterwards (you may not be able to sleep).

That was the protocol in the 80's-- don't know what the kids are doing today (but probably a good idea to stay off the internet).
