For my desert dwelling comatose friend and his bloodied cat...?

MESCALINE, PEYOTE AND THE LAW
Both mescaline and Peyote are illegal under the statutes of the [U.S.] Federal Government and most States. Members of the Native American Church are permitted the ritual use of peyote because they established it as a religious sacrement long before these laws came into existence. Members are not permitted to use mescaline, however. Several other cacti such as San Pedro also contain mescaline. Technically it would be illegal to possess these, but because they are common ornamental plants it is permissable to use these cacti for normal horticultural purposes. If a person should attempt to use any of these plants for a psychedelic experience, prosecution is possible. If he were to extract the mescaline from these, the alkaloid would definitely be contraband material. It is important that this point be made clear because the mescaline extraction process is given in this guide. To extract the alkaloids from Doñana and other non-mescaline bearing cacti is not illegal. The information in this guide is presented for the sake of furthering knowledge. The Author can assume no responsibility for how anyone may apply it.
