Medical Marijuana Laws by State

Created byВ FindLaw’s team of legal writers and editors | Last updated October 18, 2019

Patients whose physicians recommend medical marijuana for certain illnesses and chronic conditions are exempt from criminal prosecution in states that have passed medical marijuana laws. A growing number of states (and the District of Columbia) have medical marijuana laws, although federal law makes no such exceptions from the current drug prohibition policy.

Medical marijuana laws vary drastically in their scope and implementation, including the regulation of dispensaries. Some states only allow terminally ill patients to legally use marijuana, for example, while others are much less restrictive. For general information, including how these laws interact with federal law, see the medical marijuana laws page in FindLaw’s Criminal Law section.

The following state-specific guide should help you get up to speed on current medical marijuana laws:

Ballot Measure #8 passed in 1998 and was enacted in 1999. Patients whose physicians advise in writing that they “might benefit from the medical use of marijuana” may use, possess and cultivate marijuana for personal use.

After securing a physician’s recommendation, patients must apply for a Registry Identification Card for Medical Use of Marijuana in order to be considered compliant.

Arkansas Constitution of 1874: Amendment 98, section 1, et seq.

Proposition 215, passed in 1996, was the nation’s first medical marijuana law (California Bureau of Medical Cannabis). Eligible patients must present a “written or oral recommendation” from their physician.

Guidelines passed in 2003 set limits for possession and cultivation of marijuana by eligible patients and their caregivers. Although the state issues medical marijuana identification cards, registration is not mandatory for compliance.

California Health and Safety Code: Section 11362.5, et seq.

Amendment 20 passed in 2000 and took effect the following year, exempting patients with written documentation from their physicians from criminal sanctions.

The statute also recognizes qualifying patients from other states. Qualifying patients who do not have an I.D. card may raise an affirmative defense motion to dismiss marijuana possession charges.

Ballot Initiative 59 was passed by a wide margin of voters in 1998 (69%) but was blocked by city lawmakers citing a congressional ban.

The ban was lifted in 2010, followed by the passage of legislation authorizing the establishment of medical marijuana dispensaries. Patients may register online.

Medical Marijuana Age Requirement

Posted by Marijuana Doctors on 05/17/2018 in Medical Marijuana

Updated on August 26, 2020. Medical content reviewed by Dr. Joseph Rosado, MD, M.B.A, Chief Medical Officer

Currently, many states in the U.S. allow residents to possess medical marijuana. The age requirement for medical marijuana is 18 years in these states, so adults with qualifying medical conditions can use the limited number of ounces allowed in each state for medical use. However, the regulations for obtaining a medical marijuana card or a “weed card” differ from state to state.

How Old Do You Need to Be to Get Medical Marijuana?

In the states that have legalized medical marijuana, a doctor’s recommendation is required for anyone to be certified to take medical marijuana for an acceptable condition. In most of these states, minors can use medical marijuana, but they must take it under the care and supervision of a registered caregiver who’s at least 18 years old.

In nine states and Washington D.C., Americans can legally possess a certain quantity of marijuana for recreational use, as well. These states include Alaska, California, Colorado, Maine, Massachusetts, Nevada, Oregon, Vermont, Washington and the District of Columbia. In all these states, the minimum age requirement is 21 years.

This age is not a random selection — it was chosen because the brain of many young adults continues to grow even after the age of 18. This means smoking marijuana without discretion will have less of an effect on the minds of people in their mid-20s compared to those who are still teenagers.
