DMT is the simplest of the tryptamine psychedelics. Compared to other molecules, DMT is rather small. Its weight is 188 “molecular units,” meaning that it is not significantly larger than glucose, the simplest sugar in our bodies, which weighs 180, and only ten times heavier than a water molecule, which weighs 18. By comparison, consider the weight of LSD at 323, or of mescaline at 211.16
