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.

Alaska Stat. 17.37.10, et seq.

Proposition 203 passed in 2010, allowing use and possession of marijuana for patients with “written certification” from their physician.

The law recognizes “visiting qualifying patients,” those with valid doctor’s recommendations from other medical marijuana states.

Arizona Rev. Statutes 36-2801, et seq.

Voters approved passage of the Arkansas Medical Marijuana Amendment , known on the ballot as Issue 6, on Nov. 8, 2016. The measure removes criminal sanctions against those who use medical marijuana under doctor’s orders, although dispensaries and cultivation centers have yet to be developed.

Patients who want access to medical marijuana must apply with the state, including a written certification from a physician licensed in the state.

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.

While the state maintains a confidential registry and issues identification cards, patients who do not join the registry and are arrested for possession or cultivation of marijuana may argue an “affirmative defense of medical necessity.”

Colorado Constitution Article XVIII 14; Colorado Revised Statutes 18-18-406.3, et seq.

Public Act 12-55 was signed into law by the governor on June 1, 2012. Patients with a qualifying “debilitating medical condition” who have obtained written certification from a physician may possess cannabis, but may not cultivate the plant.

Delaware’s governor signed Senate Bill No. 17 into law in May 2011 that permits the medical use of marijuana with a doctor’s recommendation by those 18 and older.

Qualifying patients must have written documentation from their physician, which is then sent to the state Department of Health and Social Services for the issuance of a mandatory I.D. card. 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.

Louisiana law ostensibly allowed physicians licensed in the state to recommend the use of medical marijuana for certain seriously ill patients for decades. But it wasn’t until 2017 that legislation was signed into law to establish a legal framework for medical cannabis.

The new law is expected to provide protections for patients, caregivers, and physicians, in addition to licensing protocols and other regulatory controls.

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.

Medical and Recreational Marijuana Age Requirements by State

As stated above, the age requirement to qualify for medical marijuana vary depends on the state in which a person lives. Here is a list of the legal states, along with the regulations and age requirements for accessing cannabis as a patient and as a caregiver:
