In the lab of Dr. Bryan Roth, experiments are underway to remove the powerful hallucinogenic effects from psychedelic drugs.

“There’s one receptor in the brain that psychedelics bind to,” he said, referring to the serotonin 5-HT-2A receptor. “What we’re trying to find is drugs that bind to that receptor (and) activate it, but don’t cause a psychedelic experience and are anti-depressant.”
