Apparently so, going by your signature!
I may or may not have experimented with some things.
Mary Jane - a nice introspective time, good to listen to music to, beware fresh cheese pizza, if you swallow too much smoke you'll vomit uncontrollably and it will be terrible. I also always get TERRIBLE "blazeovers" where I feel lethargic and depressed the day after, and often cry for no reason.
Fake Mary Jane (marketed as "Genie") - about the same as regular Mary Jane, but made of mystery chemicals.
Dr. Rockso's drug of choice - the best 20 minutes you'll ever have, and then you just want more. Good for studying Japanese, you'll get a high test score.
MDMA - go to a rave and shit w0000000000t. highly addictive (or maybe it's just me), probably shouldn't do it more than once.
Adderall - They call it "diet coke" for a reason. Good for study.
Shroooooooms - Only one experience, broad daylight in Amsterdam the day after Christmas, had a lovely trip with two of my best friends (both female). Probably not a good idea to do in mixed company because sometimes nudity is necessary. You can understand the 1970s.
