1. MDMA - by far my favorite drug. I've been doing it for 3+ years. With the right people/setting/music, the MDMA experience is unrivaled.
2. LSD - Love how it puts everything in perspective, makes everything a lot more interesting.
3. Mushrooms - Sometimes a very dark experience, but it does help me make difficult, but correct, decisions
3. Marijuana - fun, day-to-day psychedelic, can be very insightful and helps me break out of bad habits (at least it shows me the error of my ways)
4. Speed - Helps me with depression, very good for dancing, makes social interaction more fun.
