Recreational Use
While it is occasionally used recreationally for its hallucinogenic properties, the experiences are often extremely mentally and physically unpleasant, and frequently physically dangerous, so repeated use is rare.
The use of medical scopolamine/opioid combination preparations for euphoria is uncommon, but does exist and can be seen in conjunction with opioid use. Doses of scopolamine by itself near the therapeutic range can create euphoria and anxiolysis of anticholinergic origin, similar to that of some first-generation antihistamines and similar drugs.
Another separate group of users prefer dangerously high doses, especially in the form of datura preparations, for the deliriant and hallucinogenic effects. The hallucinations produced by scopolamine, in common with other potent anticholinergics, are especially realistic, with many users reporting hallucinations such as spiders crawling on walls and ceilings, especially in the dark. While some users find this pleasant, often the experience is not one the user would want to repeat. An overdose of scopolamine is also exceedingly unpleasant physically, and can be fatal, unlike the effect of other more commonly used hallucinogens. For these reasons, naturally occurring anticholinergics are rarely used for recreational purposes.
Scopolamine in transdermal, oral, sublingual, and injectable formulations can produce a cholinergic rebound effect when high doses are stopped. This is the opposite of scopolamine's therapeutic effects: sweating, runny nose, abdominal cramps, nausea, vomiting, vertigo, dizziness, irritability, and diarrhea. Psychological dependence is also possible when the drug is taken for its tranquilizing effects.
