Summary
This study looked at how Delta-8 THC, a compound similar to the main psychoactive ingredient in cannabis, affects people compared to Delta-9 THC and a placebo. 28 healthy adults took the substances by mouth or by inhalation. Researchers measured their mood, thinking skills, and collected samples of saliva, urine, blood, and hair to understand the differences. The goal was to learn more about Delta-8's effects, not to treat any disease.
