Summary

This trial is looking at whether terpenes can help relieve pain when used alone or in combination with THC.

Who is the study for?
This trial is for adults aged 21-55 who use cannabis recreationally 1-7 times a week and are not seeking treatment for cannabis use. They must have a BMI of 18.5 - 34kg/m2, be able to do all study tasks, and use contraception. People with significant illnesses, pregnant women, those allergic to cannabis or on certain medications can't join.
What is being tested?
The study aims to evaluate the pain-relief and subjective effects of terpenes both alone and when combined with THC. Participants will receive varying levels of Beta-Caryophyllene (high/low), Myrcene (high/low), THC (high/low), or placebo in different sessions.
What are the potential side effects?
Possible side effects may include typical reactions to cannabis such as changes in mood, sensory perception, altered cognitive function, dry mouth, red eyes, increased appetite and possible discomfort from the Cold Pressor Test used in the study.
