Actually you can grow DMT. It occurs naturally in canary grass but i think that grass has been illegal for some time and getting seeds may be hard. Plus DMT's "buzz" feels more like being sucked into a black hole, especially at larger doses. It only lasts 15 minutes but if youre smoking the synthetic you'll be lucky if you can put down your lighter before your paralyzed. At high doses, visual reality will appear to crack apart and fly away into hyperspace along with all sense of sound or touch. I have only tried DMT a few times when i couldnt find any weed but i can say for certaain that being blind, deaf, and feeling totally and completely alone in the universe isnt the greatest of times.
