Summary

This trial studies how cannabis affects older adults, to see if it helps relieve pain.

Who is the study for?
This trial is for healthy adults aged 65 or older who have used THC or cannabis at least once in the last decade. They must be able to consent and speak English. People with abnormal heart tests, psychiatric disorders, regular use of certain drugs affecting pain perception, serious medical conditions, allergies to sesame oil/THC/cannabis, neurological issues affecting pain response/balance, untreated high blood pressure, or major cognitive disorders cannot join.
What is being tested?
The study is testing how different doses of THC (2mg and 4mg) taken orally or vaporized affect older adults compared to a placebo. It's looking at how quickly THC enters the bloodstream (PK) and its effects on pain tolerance and potential for abuse (PD). Participants will try each form under controlled conditions.
What are the potential side effects?
Possible side effects include dizziness, dry mouth, changes in appetite or mood swings due to THC's psychoactive properties. There may also be short-term memory impairment and coordination issues which are common with cannabinoid use.
