Black beans from these trees are toasted, pulverised and mixed with ashes, calcined shells or edible lime powder to make psychedelic snuff called yopo by Indians in Orinoco basin in Colombia, Venezuela and possibly in southern part of Brasilian Amazon. Yopo is blown into the nostrils through bamboo tubes or snuffed by birdbone tubes. The trees grow in open plain areas, and leaves, bark and seeds contain DMT, 5-MeO-DMT and related compounds (Schultes 1976,1977; Pachter et al. 1959).
The snuff acts rapidly and violently. Effects include excitement, numbness of the limbs, twitching of facial muscles, nausea, hallucinations and finally a deep sleep; macroscopia is frequent and enters into Waika beliefs about the spirits resident in the drug.
These seeds are sold as ornaments and the information is given purely for informational purposes. It is worth noting extraction of DMT is highly illegal in most countries;
