Clinical Trial Summary

The goal of the study is to evaluate how cannabis use affects memory and thinking skills and response to stress in older adults. The study will also relate cannabis use to Alzheimer's Disease (AD) biomarkers (measurable substances in blood that indicate condition), and test whether sex and hormones play a role in these effects. The study is recruiting adults between the ages of 50 and 80 who use cannabis products on a regular basis. Study participation will last about two weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Global Cognitive Ability (GCA)	The primary outcome is the mean Global Cognitive Ability (GCA) z-score, which is a psychometrically robust, factor analytically-derived, demographically-normed index of global cognitive function. Lower z-scores represent a lower level of cognitive function. The investigator will test the hypothesis that women with CUD will have lower GCA scores than men.	Day 0 to Day 8
