I think the first step is to learn as much as you can about it, I definately recommend checking Terence Mckenna's views on DMT
on youtube or elsewhere. Also there are some previews on a movie called "DMT the spirit molecule", with tons of info. I've never tried DMT but hopefuly someday swIm
will. The way swIm wants to do it is to get as many lsd
-mushroom-cactus trips under his belt before going into DMT, not because swIm thinks they would "prepare" him (they say nothing can) but because its more like stepping stones and swIm might be able to make more sense of it. Anyway, swIm thinks that as long as you know what you are getting into you should do it. From what swI'm has heard you should get a glass pipe, or some kind of pipe that can get a ton of the stuff into your lungs, apparently its hard to take aswell. Make sure to take all of the safety precautions you can learn of which includes the hard-to-get smart tripsitter. The great thing about it is that it only last 5 minutes or so. Do report back if and when you do!
