NCT ID NCT05865470
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how age and sex influence the effects of THC, the main psychoactive ingredient in cannabis. Researchers will give smoked and oral THC to 103 adults aged 18-65 who use cannabis regularly. They will measure pain relief, intoxication, impairment, and how the body processes THC. The goal is to understand why people react differently to cannabis based on age and sex.
