Mescaline is an alkaloid obtained from the cactus Lophophora williamsii (Anhalonium williamsii, A. lewinii) (Cactaceae), which grows in the northern regions of Mexico. The cactus is known in those areas by the Aztec name ‘peyote’ or ‘peyotl’ and dried slices of the cactus are called ‘mescal buttons’. Mescaline produces hallucinogenic and sympathomimetic effects similar to those produced by lysergide, but it is less potent. Its effects last for up to 12 hours. It has no therapeutic use. Both Mexican and North American Indians have used peyote in religious ceremonies on account of its hallucinogenic activity.


Peyote consumed during a ceremonial ritual was believed to have caused botulism in three men.1 The sample was found to contain type B botulinum toxin when assayed.
