Datura wrightii, commonly known as sacred datura, is a poisonous perennial plant species and ornamental flower of the family Solanaceae native to the Southwestern United States and northwestern Mexico. It is sometimes used as a hallucinogen due to its psychoactive alkaloids. D. wrightii is classified as an anticholinergic deliriant.

The Chumash are a Native American people of the central and southern coastal regions of California, in portions of what is now Kern, San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south to Mt Pinos in the east. Their territory includes three of the Channel Islands: Santa Cruz, Santa Rosa, and San Miguel; the smaller island of Anacapa was likely inhabited seasonally due to the lack of a consistent water source.
