AP projects that the use of medical marijuana has been approved by Massachusetts voters, with 30 percent of the precincts in.

The vote makes Massachusetts the 18th state to legalize medical marijuana through state approved distribution centers next year.

Question 3 on the state ballot states:

This proposed law would eliminate state criminal and civil penalties for the medical use of marijuana by qualifying patients. To qualify, a patient must have been diagnosed with a debilitating medical condition, such as cancer, glaucoma, HIV-positive status or AIDS, hepatitis C, Crohn’s disease, Parkinson’s disease, ALS, or multiple sclerosis. The patient would also have to obtain a written certification, from a physician with whom the patient has a bona fide physician-patient relationship, that the patient has a specific debilitating medical condition and would likely obtain a net benefit from medical use of marijuana.

The proposed law would allow patients to possess up to a 60-day supply of marijuana for their personal medical use. The state Department of Public Health (DPH) would decide what amount would be a 60-day supply. A patient could designate a personal caregiver, at least 21 years old, who could assist with the patient’s medical use of marijuana but would be prohibited from consuming that marijuana. Patients and caregivers would have to register with DPH by submitting the physician’s certification.

Marijuana legalization measures are also before voters in Colorado, Arkansas, Washington and Oregon.

Massachusetts is also considering measures on the "death with dignity" and motor vehicle repair information.
