LANSING, Mich. (AP) — Michigan regulators have significantly expanded the list of conditions approved for treatment by medical marijuana.

The Department of Licensing and Regulatory Affairs on Monday added 11 medical conditions deemed debilitating by the Michigan Medical Marihuana Act of 2008. They are: arthritis, autism, chronic pain, colitis, inflammatory bowel disease, obsessive compulsive disorder, Parkinson's disease, rheumatoid arthritis, spinal cord injury, Tourette's syndrome and ulcerative colitis.

Denied conditions include anxiety, asthma, brain injury, panic attacks, depression and diabetes.

Existing entries on the list include post-traumatic stress disorder, cancer, glaucoma, HIV, AIDS, Crohn's disease, Alzheimer's disease, and severe and chronic pain.

Officials say they received public comments related to petitions to add conditions to the list. They add the final decisions reflect changes in state law to include marijuana-infused products and advancing research.
