Belladonna, or deadly nightshade, contains alkaloids like atropine and scopolamine, which can stay in the human system for several hours to a few days, depending on factors like dosage, metabolism, and individual health. Generally, the effects of belladonna may last between 6 to 12 hours, but traces can be detected in urine for up to a week. It's important to note that belladonna is highly toxic and should only be used under medical supervision.
