Summary

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