SUMMARY: Sixty-three percent of voters approved Proposal 1 on November 4, 2008. The law took effect on December 4, 2008. It removes state-level criminal penalties on the use, possession and cultivation of marijuana by patients who possess written documentation from their physicians authorizing the medical use of marijuana. Patients diagnosed with the following illnesses are afforded legal protection under this act: Cancer, glaucoma, positive status for human immunodeficiency virus, acquired immune deficiency syndrome, hepatitis C, amyotrophic lateral sclerosis, Crohn’s disease, agitation of Alzheimer’s disease, nail patella, or the treatment of these conditions. Patients are also offered legal protection if they have a chronic or debilitating disease or medical condition or treatment of said condition that produces 1 or more of the following: cachexia or wasting syndrome; severe and chronic pain; severe nausea; seizures, including but not limited to those characteristic of epilepsy; or severe and persistent muscle spasms, including but not limited to those characteristic of multiple sclerosis. Patients (or their primary caregivers) may possess no more than 12 marijuana plants kept in an enclosed, locked facility or 2.5 ounces of usable marihuana. The law establishes a confidential state-run patient registry that issues identification cards to qualifying patients. The state officially began accepting applications for the program on April 6, 2009.

Authorizes visiting qualifying patient with registry identification card (or its equivalent) from a State that also allows the medical use of marijuana by visiting qualifying patients, to engage in the medical use of marijuana.
