ClinConnect Summary

This clinical trial is studying how cannabis affects memory in everyday life. Researchers want to understand if inhaling cannabis vapor impacts different types of memory, including how we remember things we need to do, verbal tasks, and even how we recall information over time. The study is open to adults aged 18 and older who have used cannabis regularly for at least a year. Participants will need to refrain from using cannabis for at least 8 hours before their testing session.

During the study, participants will wear a wristband to monitor their physical responses and provide saliva samples to measure stress levels. They will undergo memory tests after inhaling either cannabis or a placebo (a substance with no active ingredients). The researchers hope to find that those who inhale cannabis will perform worse on memory tests compared to those who inhale the placebo. This trial is currently recruiting participants, but certain health conditions, like serious psychiatric disorders or a history of adverse reactions to cannabis, may prevent someone from taking part.
