The University of Auckland and the University of Otago in New Zealand have received approval to begin trials utilizing MDMA—a psychoactive drug also known as “Ecstasy”—to treat tinnitus, reported.

In previous placebo-controlled studies, researchers have given study participants a small dose of the drug; some participants reported a decrease in tinnitus symptoms, according to the article. Obviously, given MDMA’s reputation as a “party drug” and its status as a controlled substance, there could be legal issues with recommending the drug as a treatment for tinnitus.
