Summary
This trialaims to study the brain mechanisms of cannabis to treat pain in humans, as it has been a promising therapy for many pain conditions but has yet to be clinically proven.
Who is the study for?
This trial is for adults aged 21-65 who have used cannabis before but are not currently dependent on it or using any form. They must be free from major medical conditions, psychiatric disorders like schizophrenia or bipolar disorder, and cannot be pregnant or nursing. Participants agree to avoid opioids, barbiturates, and driving within 4 hours after using study cannabis.
What is being tested?
The study is testing how vaporized cannabis (active ingredient THC) versus a placebo (no active ingredient) affects pain relief by looking at the brain's response to acute pain. Researchers aim to understand the neural mechanisms behind why cannabis might alleviate pain.
What are the potential side effects?
While specific side effects aren't listed here, typical reactions to cannabis may include dizziness, dry mouth, altered senses/perception, mood changes, slower reaction times and in some cases anxiety or discomfort.
