Colorado's chief medical officer says the state should make post-traumatic stress disorder a condition that can be treated with medical marijuana.

The state's Board of Health has rejected multiple requests to add PTSD to the list of conditions approved for treatment by medical pot. But now the request is coming with the backing of chief medical officer Dr. Larry Wolk, and a panel of physicians assembled to make recommendations about the medical marijuana registry. 

Colorado now has more than 100,000 people on that registry. They have a doctor's recommendation to use pot to treat debilitating conditions like cancer, AIDS, nausea and pain.

If approved by the health board, PSTD would be the first ailment added to Colorado's medical pot program since voters passed it in 2000.
