Medical-marijuana skin patch may be marketed in Colorado.

Michigan's two-year-old law allowing the use of marijuana for medical purposes is leaving communities, courts, patients and police locked in disputes over what is legal and what isn't. 

Medical Marijuana Delivery Systems said Tuesday it has acquired the U.S. patent rights to a medical-marijuana skin patch and seeks to sell it in Colorado. The patent provides Seattle-based MMDS with exclusive rights for development of the patch for trans cut aneous delivery of medical marijuana to humans and animals.
The patch will be marketed under the trademark Tetracan and is expected to be available at medical-marijuana dispensaries across the United States by year's end.
MMDS said the patch can be used for treatment of arthritis pain, the side-effects of chemotherapy, multiple sclerosis and other chronic conditions. The company said it is in discussions with the Medicine Wheel Project for the distribution of Tetracan and potential future products in the medical-marijuana states of Colorado and California.
