Psychedelic Mind

Scientists have found a pharmacological 'off-switch' for psychedelic journeys. By blocking a single serotonin receptor in the brain, a drug called ketanserin can dramatically shorten and reduce the effects of substances like LSD. This discovery not only confirms the critical role of the 5-HT2A receptor in creating psychedelic states but also offers a powerful safety tool. It provides a reliable way to end a difficult experience, making therapeutic use of psychedelics safer and more controlled.
