I've used marijuana, cocaine, mdma, lsd, mescaline, ketamine, crystal meth..I think that's about it, I may be forgetting one or two.
In my experience most of them give you the little push you need, but they will not open your mind on their own, you need to use them not as a tool, but as an aid.
Mdma will open your mind up greatly while you're on it, but you'll lose most of your realizations in the days after because of the terrible comedown. If there was/is a way to get rid of the weeklong depression there would be great benefit I guess.
Cocaine can be great if you take it while focused and manage to keep focused on expanding your mind, otherwise you'll just be like "f%*! this, let's party" and keep taking coke and having all kinds of fun until it runs out and you're mad at the world.
Mescaline will give you a great visual trip, but that's about it, once it's over you're not even sure if you were ever on it or not, it just feels like you never took it.
Ketamine would be good if you can get the exact right amount. Too little won't make you feel anything and too much will have you slipping in and out of conscience in a very uncomfortable manner (although I managed to have fun even in this stage, but it won't really help you at all).
Lsd is really really great, it changed my life forever each time I took it, not in the way I expected it to before I took it for the first time (or the way you're expecting it to if you've never taken it before), things are still so much the same, but there's a real subtle change I can't quite put my finger on. It's like my mind can really go deep on a lot of things, which I never could before lsd, it's like it has made me not be afraid to let my imagination free.
And crystal meth won't really give you any insights, it'll only give you great confidence, which can balance all your fears and inhibitions out, and your mind will never get tired while on it, you'll stay awake for 48+ hours before you're able to sleep, and then you'll wake up still energized and jittery.
And marijuana, which is the only thing I still take regularly, will make your life just a tad bit more "fantastical", and make you have some really deep thoughts, but if you don't know how to handle it, it can make you really dumb or even cause paranoia to the point of schizophrenia. At least I think that's where I was headed before my mind underwent a great change and I became interested in magick and all things occult. Also marijuana can really make you obsessive-compulsive after you develop a tolerance to it and can't get high as you want no matter how much you smoke.
But all these can only help you if you're already working on it in some way, for example I've always been a fan of daily meditation, but everybody has his own way of opening his mind up.
And a little disclaimer, I don't advocate drug use, and most of the substances I've mentioned are really harmful, so you're best off developing your mind in natural ways. Then again, everybody has his own combination of fate and choices, so do what you will, but never be too quick to decide to take a substance, give it careful thought and research before doing anything because I've seen countless people's life ruined because of them, they're not for everybody I guess. Best of luck to everybody (IMG:
