LANSING, Mich. (AP) — A state panel has recommended that severe forms of autism be added as a condition that qualifies for medical marijuana in Michigan.

The Michigan Medical Marijuana Review Panel voted 4-2 Friday to recommend its use.

The group’s recommendation will go to the Department of Licensing and Regulatory Affairs, which makes the final decision.

Supporters say oil extracted from marijuana has been effective in controlling severe physical behavior by kids with autism. Critics say there’s still not enough research.

Only one condition, post-traumatic stress disorder, has been added since voters approved medical marijuana in 2008 for the side effects of cancer, glaucoma and a few other conditions.
