ST. PAUL, Minn. (AP) — Gov. Mark Dayton says prospects for a study on one type of medicinal marijuana stand between "slim and none" because advocates for broader legalization don't appear interested.

Dayton says his proposal to spend more than $2 million to research a non-combustible form of marijuana lacks support. The study would have been conducted by Mayo Clinic doctors and was to involve pill or liquid marijuana extracts as a therapy for epileptic children.

Dayton's staff offered the marijuana study as a compromise.

Heather Azzi of Minnesotans for Compassionate Care says her group is still working toward a possible accord.

The Democratic governor has ruled out supporting legalization of marijuana that involves smoking the drug. He has aligned himself with law enforcement concerns on the issue.
