Lophophorine
Lophophorine, also known as N-methylanhalonine, is a tetrahydroisoquinoline alkaloid made by various cacti in the Lophophora family. It has been found to lack hallucinogenic effects in humans. Arthur Heffter tried lophophorine at a dose of 20mg resulted in vasodilation, an immediate headache, and a warm flushed feeling, effects which dissipated within an hour. It has also been said to produce nausea in humans. Lophophorine is described as highly toxic and produces strychnine-like convulsions in animals.
