United States v. Hemani: Pot, Powder, Pistols and the Past Collide

On June 18^th, in a unanimous decision, the Supreme Court held that the federal government cannot constitutionally apply a blanket firearms ban to all unlawful drug users simply because they use illegal drugs.

The Court’s analysis centered on the distinction between prohibiting dangerous conduct and prohibiting firearm possession based on a person’s status.

So, what does this mean? Can those with a medical marijuana card now be able to possess a firearm? Can a cocaine user keep their coke and their Colt? Well, It’s not quite that black and white.

What the Supreme Court Decided in United States v. Hemani

The Court did not strike down § 922(g)(3) in its entirety. Instead, it held that the statute was unconstitutional as applied to Ali Danial Hemani, a nonviolent Texas man who was not alleged to have been intoxicated while possessing a firearm.

The opinion leaves open the possibility that firearm prohibitions may still be constitutional when applied to individuals who are actively impaired, addicted or otherwise shown to pose a heightened danger.

The court’s reasoning stems directly from Bruen, which requires the government to demonstrate that modern firearm restrictions are consistent with the Nation’s historical tradition of firearm regulation. Because historical laws targeted the dangerous use of firearms while intoxicated rather than the mere status of being a drug or alcohol user, the Court found that the government failed to identify a sufficiently similar historical analogue to justify disarming Hemani.

Looking to historical regulations, Justice Gorsuch noted that early American laws often punished the misuse of firearms while intoxicated but generally stopped short of disarming individuals simply because they consumed intoxicating substances.

As the Court explained, “our tradition supports disarming individuals who pose a credible threat to the physical safety of others. But it does not support disarming a person solely because he belongs to a category of people who may be dangerous.”

That principle proved decisive in Hemani’s case. Although the government argued that unlawful drug users as a class present heightened risk, the Court concluded that the Second Amendment requires a stronger historical justification before an otherwise peaceable citizen can be stripped of the right to keep and bear arms.

The Facts Behind United States v. Hemani

Hemani’s case began in 2022 when the FBI executed a search warrant at his Texas home during an investigation unrelated to firearms possession.

The FBI executed a search warrant at the Hemani family home as part of an investigation into suspected terrorism-related activities. Although the search uncovered a firearm, marijuana and cocaine, no terrorism charges were ever filed.

During the search, agents discovered a Glock 9mm pistol along with the marijuana and cocaine. Hemani admitted that he regularly used marijuana, and federal prosecutors charged him under 18 U.S.C. § 922(g)(3), the federal law that makes it a felony for anyone who is an “unlawful user of or addicted to” a controlled substance to possess a firearm.

One of the interesting aspects of the case is that cocaine was found during the search, but the government’s prosecution was not really based on cocaine possession. According to the Supreme Court opinion, FBI agents found marijuana in Hemani’s room. They later found cocaine in his parents’ closet, and Hemani claimed ownership of it, although he maintained that he had not used it recently.

Furthermore, the government did not allege that Hemani was intoxicated while possessing the firearm, had used the firearm in connection with any criminal activity or otherwise posed a danger to the public.

Instead, the prosecution rested solely on the fact that he possessed a firearm while also being a user of substances prohibited under federal law.

Hemani challenged the charge, arguing that the law, as applied to him, violated the Second Amendment, a challenge that ultimately reached the United States Supreme Court.

The Long History Behind Federal Drug Laws

The debate surrounding marijuana prohibition has intensified in recent decades. Supporters of legalization argue that cannabis has recognized medical benefits, poses fewer risks than many legal substances (like alcohol) and was historically used for centuries before modern prohibition. Opponents cite concerns about addiction, impaired driving, youth access and public health effects. These competing views have led to a patchwork system in which many states permit marijuana use while federal law continues to prohibit it.

Cannabis first became heavily regulated under the Marihuana Tax Act of 1937, which effectively criminalized much of its possession and distribution. Cocaine faced federal regulation earlier through the Harrison Narcotics Tax Act of 1914, enacted amid growing concerns about addiction and public health.

Federal restrictions on both substances developed gradually throughout the 20th century.

The modern legal framework for both marijuana and cocaine was established with the Controlled Substances Act of 1970. Congress classified marijuana as a Schedule I controlled substance, concluding that it had a high potential for abuse and no accepted medical use under federal law. Cocaine was placed in Schedule II, recognizing its accepted medical applications while still imposing strict controls due to its potential for abuse. I know, crazy right?

These classifications remain in place today and form the basis for numerous federal criminal statutes, including 18 U.S.C. § 922(g)(3).

From Ancient Use to Modern Prohibition

To understand why cannabis and cocaine are treated so differently under federal law, it helps to look at how both substances were viewed prior to modern prohibition. Long before either substance became the subject of federal criminal law, cannabis and cocaine were widely used throughout the world for medicinal, industrial and cultural purposes. Cannabis has been cultivated for thousands of years, with evidence of its use dating back to ancient China, India, and the Middle East.

In the United States, hemp, a variety of cannabis, was an important agricultural crop used to produce rope, paper, textiles and other goods. Cannabis extracts were commonly sold in pharmacies during the 19th and early 20th centuries and were prescribed to treat ailments ranging from pain and insomnia to migraines and digestive issues.

Cocaine has a similarly lengthy history. Indigenous peoples in South America chewed coca leaves for centuries to combat fatigue and altitude sickness. After cocaine was isolated from the coca plant in the mid-1800s, it gained popularity in Western medicine as a local anesthetic and was even included in various consumer products, infamously Coca-Cola, before concerns about addiction and abuse emerged.

How History Shaped the Court’s Decision

When the Supreme Court discusses historical traditions of disarming “dangerous” persons, cocaine presents a stronger historical argument for regulation because concerns about intoxication, addiction and violence were among the reasons federal restrictions were enacted.

Marijuana’s history is more complicated because much of its prohibition stemmed from broader social and political factors rather than a long-established tradition of treating users as inherently dangerous.

What Happens Next?

The Supreme Court made clear that the federal government cannot automatically disarm every unlawful drug user based solely on status. But it also left room for future cases involving people who are actively impaired, addicted or otherwise shown to pose a heightened danger.

For now, marijuana remains illegal under federal law, cocaine remains strictly controlled, and the ATF’s existing forms and guidance have not yet been revised to reflect Hemani. More litigation will likely determine just how far Hemani reaches. Until then, gun owners should understand that this ruling narrowed the government’s power to apply § 922(g)(3), but it did not erase the federal law entirely.

FAQs

What did the Supreme Court decide in United States v. Hemani?
In a unanimous decision, the Supreme Court held that the federal government cannot constitutionally apply a blanket firearms ban to all unlawful drug users simply because they use illegal drugs. The Court focused on the difference between prohibiting dangerous conduct and disarming someone based only on status.

Did the Court strike down 18 U.S.C. § 922(g)(3)?
No. The Court did not strike down § 922(g)(3) in its entirety. Instead, it held that the statute was unconstitutional as applied to Hemani, who was not alleged to have been intoxicated while possessing a firearm or to have used the firearm in connection with criminal activity.

Can medical marijuana users now legally possess firearms?
A medical marijuana card does not automatically restore or guarantee firearm rights under federal law. Marijuana is still classified as a Schedule I controlled substance.

Why did the Court rule in Hemani’s favor?
The Court found that historical firearms laws generally punished the misuse of firearms while intoxicated rather than disarming people simply because they consumed intoxicating substances. Under Bruen, the government had to show that the modern restriction fit within the nation’s historical tradition of firearm regulation.

Can someone still be barred from possessing firearms because of drug use?
Possibly. The opinion leaves open the possibility that firearm prohibitions may still be constitutional when applied to individuals who are actively impaired, addicted or otherwise shown to pose a heightened danger.

Does Hemani change ATF Form 4473?
The ATF’s existing forms and guidance have not yet been revised to reflect the impact of Hemani.

Why were marijuana and cocaine both discussed in the case?
FBI agents found marijuana in Hemani’s room and later found cocaine in his parents’ closet. Hemani claimed ownership of the cocaine but maintained he had not used it recently. The article notes that the government’s prosecution was not really based on cocaine possession but on firearm possession while being a user of substances prohibited under federal law.

What does Hemani mean for future gun-rights cases?
Additional litigation will likely determine how broadly Hemani applies, especially for medical marijuana patients and others affected by the federal “unlawful user” provision.
