Datura refers to a group of flowering plants that secrete a variety of substances, with some of them being poisonous. The plants belong to the nightshade family, and they are commonly called Devil's trumpets, Jimson's weed, Thornapple, Hell's Bells, Devil's weed, and Moonflower. Some of the substances can be psychoactive. Some compounds are hallucinogenic, with specific compounds playing a role in religious rituals traditionally practiced by Native American groups, particularly those that resided in the Desert Southwest. These religious ceremonies are typically supervised by a religious guide, such as a shaman. Poisonous compounds from this planet can lead to fever, delirium, cardiac arrhythmia, and respiratory depression. An overdose of the substances from these plants can be fatal.
