Jimsonweed (aka datura stramonium, loco weed, etc) is a poisonous plant.
It contains belladonna alkaloids including Atropine and scopolamine. These can cause nausea, vomiting, high fever, urinary retention, confused thinking, hallucinations, bizarre and even violent behavior, seizures, coma, and death. Although this plant grows wild in many places, i would not recommend smoking or ingesting it.
