Lack Of Analgesia By Oral Standardized Cannabis Extract On Acute Inflammatory Pain And Hyperalgesia In Volunteers

Effect None
Trial Design Double blind
Trial Length 24 hours
Number of Subjects 18
Gender Female
Age Range 18-29
Body Types Average
Notes for this study:
In 18 otherwise healthy female volunteers who ingested 20mg THC with a meal and then were tested on various pain tests, there was a failure for THC to reduce pain in a capsaicin intradermal test (2.5 hours after ingestion) despite this being in the time range of peak plasma THC concentrations (2-4 hours). The pain associated with a sunburn test was also not affected any differently than placebo.

This dose of marijuana did not affect blood pressure (despite an increase in heart rate) and had psychoactive effects.
