Summary
This study looked at whether giving ketanserin, olanzapine, or lorazepam after taking LSD can make the LSD effects weaker or end sooner. Twenty healthy adults took LSD alone or with one of these drugs, and researchers measured their experiences. The goal is to learn how to manage intense or unwanted psychedelic effects, not to treat a disease.
