Ecstasy
Ecstasy, or MDMA, is more difficult to categorize as a psychedelic because the hallucinogenic effects are less pronounced, and the mood-enhancing and stimulant effects are more noticeable than some other psychedelics. However, ecstasy can induce hallucinations and delusions.

Ecstasy has also been associated with increased risks of health problems arising from overheating, dehydration, and water intoxication.
