Anhalonine, also known as 1-methyl-6-methoxy-7,8-methylenedioxy-1,2,3,4-tetrahydroisoquinoline, is a tetrahydroisoquinoline alkaloid found in Lophophora williamsii (peyote) and many other cactus species.^[1]^[2]^[3] Peyote contains 3% anhalonine.^[3] It is known to be pharmacologically active and is said to be similar in its activity to anhalonidine.^[1]^[3]^[4] Arthur Heffter tried anhalonine via self-experimentation at an oral dose of 100 mg and found that it was inactive.^[5]^[3]^[4] Anhalonine was isolated from peyote by Louis Lewin in 1888 and was bioassayed by Heffter with his report published in 1898.^[3]

Lophophorine had only mild sedative efects. Thus, there was no doubt that it was "the mescaline which exclusively caused the characteristic symptoms of a mescal[!]-intoxication, and, above all, that it solely induced the yet unprecedented visions" [15].
