High Hopes: How d-Limonene Curbs the Anxiety of THC

Study finds an essential oil, d-limonene, significantly reduces feelings of anxiety and panic, without altering the desired effects of marijuana’s active ingredient.

A Johns Hopkins Medicine-led research team has added to evidence that a chemical found naturally in cannabis (also known as marijuana) can — in the right amounts — lessen the anxiety-inducing effects of tetrahydrocannabinol (THC), the primary psychoactive sister chemical found in cannabis. The finding has the potential to advance the medicinal use of THC, and reduce the risks of its recreational use in some people.
