Jimsonweed (Datura stramonium) is well known for its toxicity to humans. The common name "Jimsonweed" is reportedly due to mass poisoning experienced by British troops who were sent to the Jamestown colony in Virginia in 1676 to suppress Bacon's Rebellion (Beverley 1705). Jimsonweed may be picked and consumed accidentally by individuals mistaking the leaves for those of another plant. More commonly, various parts (including seeds from the spiny pod, leaves, and twigs) may be consumed intentionally in order to experience their psychoactive effects (although these effects are often described even by enthusiasts of psychotropic drugs as extremely violent and unpleasant, as are accompanying symptoms). Consuming Jimsonweed is considered a dangerous practice that can even result in death. Both this and other Datura species, however, have been used in traditional spiritual practices by various New World indigenous peoples. According to Schultes (1976), Jimsonweed is believed to have been the main ingredient in wysoccan, which was used by the Algonquin Indians of eastern North America as part of the ritual of initiation into manhood.
As in other members of the genus Datura, the main active agents in Jimsonweed are the anticholinergic tropane alkaloids hyoscyamine, scopolamine, and atropine, although many other physiologically active alkaloids may also be present. Alkaloid composition and concentration may vary among plant parts as well as among individual plants. Krenzelok (2010) reviewed medical aspects of Jimsonweed poisoning and its treatment. According to Krenzelok, treatment is mainly supportive, with the careful use of the cholinesterase inhibitor physostigmine in more severe cases of poisoning.
Jimsonweed may be native to North America, probably Mexico, but it is now widespread in vacant lots, along roadsides, and in other "waste places" in temperate and warm regions around the world. Jimsonweed can be a serious agricultural weed in maize and other crops.
