And smoked or oral... I prefer oral, aya style, for times when I need a real shake/wake up...for when my brain and my ideas have become too sedated. It is an incredible cure for the negative thought loops that infect us all at one time or another.

I know someone who has extracted their own... IMO there isn't a more satisfying thing to do. It is like baking your own bread. Smoked dmt is best for Staying Psychedelic. If I ever feel like am beginning to lose my way, or get too heavily into my work (which is not psychedelic at all), a darkened room and half an hour brings me back on track
