Guam marijuana laws

Published on September 8, 2020 · Last updated August 11, 2022

Current legality status


Cannabis is legal under state law for adults 21+.

Both recreational and medical marijuana are legal in Guam. Recreational consumers may possess up to one ounce of cannabis flower, up to eight grams of cannabis concentrate, or cannabis products containing up to 800 grams of THC.

They may also grow their own plants, up to three mature (flowering) plants and three immature plants. Those who grow their own marijuana may give up to an ounce to other consumers, but selling it is prohibited.

Medical marijuana is also legal in Guam. Patients may possess 2.5 ounces of marijuana purchased from licensed dispensaries for medical use. Patients may cultivate marijuana at home, up to six mature plants and 12 immature plants at a time.

All cultivation must occur on private property and must be out of view from passers-by. Public consumption is not legal for anyone.

Because there is no licensed testing facility in Guam, no medical or recreational dispensaries have been able to open. Critics have alleged that the application and setup costs necessary to run a licensed testing facility are too steep and some have urged relaxation of residency requirements for testing facility owners.

Guam recreational marijuana laws

The Guam Cannabis Industry Act of 2019 legalized recreational cannabis use for adults 21 and over and created a system for the regulated sale of recreational cannabis. However, recreational dispensaries are not yet open in Guam.

Recreational marijuana was legalized for people 21 and over in Guam in April 2019 when the governor signed Bill 32-35, known as the Guam Cannabis Industry Act of 2019.

The act declassified marijuana as a Schedule I controlled substance and created a Cannabis Control Board to regulate and tax the sale of marijuana. The board is responsible for licensing dispensaries and may issue penalties and fines to dispensaries that do not comply with regulations.

Fines will be deposited in a Cannabis Control Fund that will subsidize cannabis prevention and substance-abuse programs. Fifty percent of excise tax revenue derived from marijuana sales will also be deposited in the Cannabis Control Fund.

The act clearly states that public consumption and intoxicated driving are both illegal.

The establishment of a recreational cannabis industry has seen numerous delays, with the COVID-19 pandemic further slowing activities of the Cannabis Control Board. As of 2020, it is still finalizing regulations to govern recreational cannabis.

Guam medical marijuana laws

Medical marijuana was legalized in 2014 by a referendum on the Joaquin (KC) Concepcion II Compassionate Cannabis Use Act of 2013. The act was placed on the ballot by Bill 215-32. The referendum passed with 56% of Guam residents in favor. With its passage, it became Public Law 33-220. Under the law, qualifying patients may possess up to 2.5 ounces of marijuana purchased from a licensed dispensary.

The legislation also stipulated the creation of an advisory board comprising the director of the Department of Public Health and Social Services, the director of the Board of Medical Examiners, the director of the Department of Agriculture, the director of the Legislative Committee on Health and Human Services, and one practitioner each in oncology, neurology, psychiatry, and pain management. A system of patient registry was also mandated, as was a system of registered cultivators, manufactures, and distributors.

In 2018, Bill 302-34 legalized the home cultivation of marijuana by medical patients, and it became Public Law 34-125. Patients or caretakers can cultivate up to six mature plants and 12 immature plants at once. Marijuana produced by these plants cannot be diverted to other patients or users.
