Scientific titleA functional magnetic imaging (fMRI) study of the effects of cannabis-based medicines (CMEs) on the neutral activity associated with noxious thermal stimulation in healthy human volunteers (CRI.FM024). Protocol V2. FINAL
Study objectivesWe wish to undertake an experimental study of the effects of cannabis-based medicines (CMEs) on the neutral activity associated with the experience of pain in healthy volunteer participants. Fifteen volunteers will complete an fMRI scanning protocol on 4 separate study days on each of which they will receive one of 3 CMEs or a placebo treatment. During the scanning protocol, volunteers will receive noxious thermal stimulation on the dorsum of the left hand. Differences in volunteers' ratings of the intensity of the pain experience, as well as differences in measures of neutral activity associated with this experience, will provide important new information about CMEs' putative analgesia and their underlying mechanisms.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSign and Symptoms: Pain
Intervention15 volunteers will complete an fMRI scanning protocol on 4 separate study days on each of which they will receive one of 3 CMEs or a placebo treatment. During the scanning protocol, volunteers will receive noxious thermal stimulation on the dorsum of the left hand.
Intervention typeOther
Primary outcome measure(s)

1. Volunteers' rating of pain during noxious thermal stimulation
