Revises medical marijuana provisions.

Changes the term "cannabis" to "marijuana."

Requires the department of health to convene a work group of representatives of the medical quality assurance commission, the board of osteopathic medicine and surgery, the nursing care quality assurance committee, the board of naturopathy, and an association representing physicians to develop practice guidelines for health care professionals to consider when authorizing the medical use of marijuana for patients and consider appropriate training and practice standards for employees of a licensed marijuana retailer that holds a medical marijuana endorsement.
