Summary

This early-stage study tested whether it's possible to measure how two cannabis compounds (delta-9-THC and delta-8-THC) affect driving skills. Five adults who had used cannabis before took part. Researchers measured drug levels in blood and saliva and checked driving performance using a simulator and sobriety tests. The goal was to see if these methods work for future, larger studies.
