What Arizona Gun Owners Need to Know in 2026
If you have—or are considering obtaining—an Arizona Medical Marijuana Card, you may be wondering how it could affect your firearm rights.
This is one of the most common questions we hear from patients, and it’s understandable why. Arizona has legalized both medical and recreational marijuana, while federal firearm laws have historically taken a different approach. That difference has created years of confusion for responsible gun owners across the state.
In June 2026, the U.S. Supreme Court issued an important decision that changed part of the legal landscape regarding marijuana use and firearm possession. While the ruling provides greater constitutional protections in certain situations, it does not eliminate every legal question involving firearms and cannabis.
In this guide, we’ll explain:
What Arizona law says
What Federal law says
What the Supreme Court’s decision changed
What it did not change
What Arizona Medical Marijuana patients should know before making decisions involving firearms
Our goal is to provide clear, factual information so you can better understand this evolving area of law.

Why This Topic Can Be Confusing
Medical marijuana is legal under Arizona law for qualified patients.
However, marijuana remains a Schedule I controlled substance under federal law, creating a long-standing conflict between state and federal law. This is why firearm ownership and medical marijuana have been such a complicated legal issue.
Arizona Law
Arizona has one of the nation’s most established Medical Marijuana Programs. Under Arizona law, qualified patients who meet the state’s eligibility requirements may legally obtain an Arizona Medical Marijuana Card through a licensed medical provider.
Arizona law does not automatically prohibit someone from owning or possessing a firearm solely because they are a registered Arizona Medical Marijuana patient. In other words, simply having a valid Arizona Medical Marijuana Card does not, by itself, make you a prohibited possessor under Arizona law.
However, it’s important to understand that firearm laws can involve both state and federal law. While Arizona’s Medical Marijuana Program provides protections for qualified patients under state law, federal firearm laws have historically taken a different approach. This difference has created uncertainty for many responsible gun owners and medical marijuana patients.
Understanding both Arizona and federal law is essential, especially as court decisions and federal policies continue to evolve.
Historical Federal Law
For many years, federal law has treated marijuana differently than Arizona law.
Although Arizona legalized medical marijuana in 2010 and later legalized recreational marijuana for adults, marijuana continues to be classified as a controlled substance under federal law.
Because of this conflict, federal law has historically prohibited certain individuals who are considered “unlawful users” of controlled substances from possessing firearms. This has been one of the primary reasons patients have questioned whether obtaining an Arizona Medical Marijuana Card could affect their firearm rights.
For years, this difference between state and federal law created uncertainty for medical marijuana patients across the country.
The Supreme Court Decision
In June 2026, the United States Supreme Court issued an important decision in United States v. Hemani, a case that addressed whether the federal government could automatically prohibit someone from possessing a firearm based solely on regular marijuana use.
The United States Supreme Court determined that, under the facts presented in that case, the government had not shown sufficient historical justification to permanently disarm the individual simply because of regular marijuana use. The decision emphasized that constitutional rights cannot automatically be restricted without considering the specific circumstances of each case.
This ruling represents one of the most significant developments in the relationship between firearm rights and marijuana use in recent years.
However, it is equally important to understand what the Court did not decide.
What Changed?
The Supreme Court’s decision means that regular marijuana use alone is not automatically enough to justify permanently taking away a person’s firearm rights under the circumstances considered by the Court.
Instead, the government must demonstrate more than marijuana use by itself when attempting to enforce federal firearm restrictions in situations similar to the one reviewed by the Court.
This decision provides important constitutional guidance and represents a significant shift from how these cases have often been viewed in the past.
What Didn’t Change?
The Supreme Court’s decision did not legalize the combination of marijuana and firearms in every circumstance.
The Court did not rule that:
Marijuana users may possess firearms while impaired.
Federal firearm laws no longer exist.
Every medical marijuana patient automatically has unrestricted firearm rights.
Every firearm purchase involving a marijuana user will automatically be approved.
Instead, the Court issued a narrow decision based on the specific facts of the case before it. Firearm laws remain an evolving area of law, and future court decisions or federal guidance may provide additional clarification.
Federal Cannabis Policy: What Has Changed?
Federal cannabis policy continues to evolve, even though marijuana remains subject to a complex mix of state and federal laws.
In December 2025, President Donald Trump signed an Executive Order directing federal agencies to expand medical marijuana research, improve scientific understanding of cannabis and cannabidiol (CBD), and expedite the federal process of rescheduling marijuana under the Controlled Substances Act.
In April 2026, the U.S. Department of Justice and the Drug Enforcement Administration announced additional actions affecting certain state-regulated medical marijuana products while broader federal rescheduling continues to move through the rulemaking process.
These developments reflect a significant shift in how the federal government views medical cannabis. However, they do not automatically eliminate all federal firearm restrictions or override state laws. Firearm rights continue to be governed by a combination of constitutional decisions, federal statutes, state law, and future court rulings.
For Arizona Medical Marijuana patients, this means the legal landscape is continuing to change—but it’s still important to understand both your rights and your responsibilities.
