This will probably never be made into an anti-drug ad campaign, but I can’t imagine a stronger deterrent.
Angel’s Trumpet is a flower that contains scopolamine and other alkaloids. It’s known as a “biogenic drug” and presumed by naive recreational drug users to be harmless because it’s a plant. However, it can cause psychosis, delirium, visual hallucinations, agitation, incoherence, aggressive behaviour, memory problems and “convulsive sobbing” as well as somatic symptoms and well, things like this incident.
A case study describes an 18-year-old male with no history of mental disorders who consumed Angel’s Trumpet and snipped off his penis and his tongue with garden pruning shears. He was rushed to hospital but the amputated parts could not be re-attached. He later had complete amnesia for the event. “… illustrating that consuming this beautiful flower with the name of an angel and the poison of the devil can be very dangerous.”
