Summary

This trial will examine the acute effects of CBD on the brain. 100% THC-free CBD will be compared to placebo, and participants will be scanned before and after ingestion. Results will help to determine if CBD has any neurometabolic or neurophysiological effects, and if it affects working memory or response inhibition.

Who is the study for?
This trial is for right-handed adults aged 21-50 who are generally healthy, with no psychiatric or neurological conditions, heart disease, stroke history, or contraindications to MRI scans. Participants must not consume certain substances before scans and cannot be on psychotropic or neurological medications.
What is being tested?
The study tests the effects of THC-free Cannabidiol (CBD) versus a placebo on brain function and behavior. It's a double-blind study where participants take CBD capsules and undergo pre- and post-ingestion brain scans in two sessions separated by a washout period.
What are the potential side effects?
While CBD is generally considered safe and non-addictive, potential side effects may include changes in alertness, gastrointestinal discomfort, mood swings, drowsiness, dry mouth, or low blood pressure.
