Project CBD, a non-profit educational service dedicated to promoting and publicizing research into the medical utility of cannabidiol, wrote in its "About Cannabidiol" page on the website (accessed Sep. 28, 2011):

“Cannabidiol —CBD— is a compound in Cannabis that has medical effects but does not make people feel ‘stoned’ and actually counters some of the effects of THC…

Scientific and clinical studies indicate that CBD could be effective in easing symptoms of a wide range of difficult-to-control conditions, including: rheumatoid arthritis, diabetes, alcoholism, PTSD, epilepsy, antibiotic-resistant infections and neurological disorders. CBD has demonstrated neuroprotective effects, and its anti-cancer potential is currently being explored at several academic research centers in the U.S. and other countries.”
