Summary
This study is testing whether simple saliva tests done at home can accurately show when someone has not used cannabis. Researchers will enroll 200 people aged 18-30 who use cannabis at least once a week. Participants will provide saliva and urine samples over 3-4 weeks, and researchers will compare the test results with self-reported cannabis use. If the saliva tests work well, they could make it easier to run clinical trials remotely without needing in-person urine tests.

Active substance
oral fluid test for THC
What this could lead to
If successful, this could provide a reliable, remote way to confirm cannabis non-use in clinical trials, reducing the need for in-person visits.
What could go wrong
This is an early-stage feasibility study with only 200 participants. The tests may not be accurate enough or easy to use at home, and results may not apply to all cannabis users.
