Yesterday, the Colorado Board of Health rejected a petition to add Tourette's syndrome to the list of conditions the state considers treatable with medical marijuana. The Denver Post reports it was the first time since 2000 "that a petition to add a new condition had made it through the state health department's review process and come before the board."
Tourette's — a neurological condition that causes involuntary verbal and muscle tics — was one of 10 conditions listed in a March petition to the health department that sought their addition to the current array of conditions approved for treatment by marijuana.
The state's chief medical officer, Ned Calonge, reviewed the evidence arguing that marijuana could help those conditions before deciding to present only Tourette's to the board for consideration.
Calonge said he looked for examples of peer-reviewed "randomized controlled clinical trials" and found two small studies by German researchers that showed THC, one of the active chemicals in marijuana, reduced tics in Tourette's patients.
The Post reports that a similar petition from MMJ advocacy group Sensible Colorado to add post-traumatic stress disorder to the state's list is still under review.
