n,n Dimethyltryptamine. Some people claim that it can be synthesized from some plants. That is not true at all. It is however, already present in some plants such as mimosa hostillis. It can be extracted from such plants by almost anyone. Its cheap and easy to extract, and yet almost nobody sells it.
The trip from DMT can last a little as 5 minutes and up to 30(smoked). Other routes of use include IV and oral consumption in combination with a monoamine oxidase inhibitor(MAOI). Oral preparation of DMT in combination with an MAOI are comonly refered to as ayahuasca, or yage. The active dose of DMT is higher than that of Lysergic Acid Diethylamide (LSD) or psilocybin, or salvinorum A. However, the trip itself is much more intense. On LSD and psilocybin you can still function. On DMT you cant do much other than stare at the floor.
Some call it god crystal because it is often sold as a crystal chunks and because of its mystical effects.
Last night I smoked 50mg of DMT and I met the great alien king who telepathically explained life and the universe to me. None of it was in English, or even any earth language, and yet I understood it all.
