National Park Drug Laws [2024 Updated]

On Behalf of The Kaiser Law Group

Arizona is home to three national parks in the United States: the Grand Canyon, Saguaro, and the Petrified Forest. All three are protected areas in the state, and it is important for anyone visiting to abide by any laws that govern them, including the drug laws. Becoming familiar with national park drug laws in Arizona can ensure that you avoid any legal consequences and that your experience remains safe and enjoyable.

Understanding Drug Laws in National Parks

It is important to know that all national parks are under federal jurisdiction and are subject to federal laws. Although it is currently legal to use marijuana in Arizona, it remains illegal on the federal level and, therefore cannot be used within a national park. In fact, the possession, use, or distribution of any controlled substance is prohibited in any national park. An individual who violates these laws can face serious consequences that include fines, jail time, and potential restrictions.

It is crucial to know and understand that the state laws regarding the use or possession of drugs have no bearing on national parks. Federal laws and regulations supersede those of the state.

Common Drug Offenses in National Parks

National parks attract millions of visitors every year, and they are not completely immune to drug offenses, despite their protected status and the efforts of the park rangers. These are some common drug offenses that occur in national parks:

  • Possession of controlled substances. It is illegal to possess controlled substances, including marijuana, ecstasy, and hallucinogenic mushrooms.
  • Use of controlled substances. Using or consuming any controlled substances while in a national park is also illegal.
  • Distribution of controlled substances. Trafficking, selling, or distributing drugs while in a national park can be strongly prosecuted.
  • Driving under the influence. Operating any vehicle while under the influence of drugs or alcohol endangers passengers and others who are visiting the park.

Being aware of the rules and regulations for drug possession and use on national park grounds not only protects the parks but also keeps all visitors safe. It is worth it, in every aspect, to respect the rules and abide by federal law.

Penalties for National Park Drug Offenses

Since national park drug laws fall under federal jurisdiction, the penalties can be severe. Of course, the penalties vary based on the type of drug involved, the amount, and if the individual has any prior drug convictions. The potential penalties for a drug offense in a national park include the following:


Oftentimes, a drug possession conviction can result in the offender being ordered to pay a fine. Depending on how severe the offense is, the fine amount can be anywhere between a few hundred dollars to thousands of dollars.


It is also possible for a person convicted of drug possession in a national park to be sentenced to jail or prison. A less serious offense can potentially result in a short period of time in jail, while people who commit more serious offenses or have offended before can be sentenced to years in prison.


In some cases, a person convicted of a drug crime may be sentenced to probation in addition to incarceration and fines. Sometimes, probation may instead be granted in lieu of time behind bars. An individual placed on probation must comply with the conditions of the probation for the amount of time ordered. Failure to comply can result in the individual having their probation revoked and serving jail or prison time.


Individuals who are convicted of a drug offense in a national park may face certain restrictions, such as not being allowed in that national park again and losing the privilege of visiting other federal lands at any point in the future.

It is important to note that first-time offenders for simple drug offenses, such as possessing a small amount of marijuana, may be awarded some leniency in their penalties. In many cases, a first-timer may not be given any jail time but instead ordered to pay a fine and possibly be put on probation. Even if this is a possibility, there is no guarantee what punishment anyone will receive for a federal drug offense, so it is a good idea to retain a lawyer.


Q. Is Alcohol Allowed in National Parks?

A. Alcohol is generally allowed in national parks in designated areas of the park. The rules and regulations regarding the consumption of alcohol vary depending on the specific park. You should be sure to check the alcohol policy of any national park that you plan to visit. That way, you can make sure that you are in compliance with the regulations during your trip. Only consume alcohol in the designated areas and in a responsible manner.

Q. Are There Exceptions for Medical Marijuana in National Parks?

A. No, there are no exceptions for medical marijuana in national parks. The federal government does not recognize the use of marijuana for recreational or medicinal purposes. Even if you have a valid prescription or a medical marijuana card, it is still illegal to use it or possess it in a national park.

Q. Is Smoking Prohibited in National Parks?

A. Smoking is prohibited in many areas of national parks that have been designated as “smoke-free” zones. This is done to protect park resources and reduce the risk of fire. Make sure you are clear on what, if any, areas of a national park have been designated as smoking areas when you visit, and be sure to follow any guidelines given.

Q. Is Vaping Allowed in National Parks?

A. Generally, vaping is not allowed in national parks. Vaping is prohibited in a national park in the same areas where smoking is prohibited. This often includes public areas in the national park and indoor facilities. Rules and regulations may be different between the parks, so it is recommended that you check the guidelines of the specific park you plan to visit.
