### Who Wins and Why

| Outcome | Market | Model | Why |
| --- | --- | --- | --- |
| Before 2026 | 14.0% | 9.2% | The Supreme Court may review Second Amendment challenges to firearm restrictions for certain users. |

## Model vs Market

- Model Probability: 9.2% (Yes)
- Market Probability: 14.0% (Yes)
- Yes refers to: Before 2026
- Edge: -4.8pp
- Expected Return: -34.6%
- R-Score: -0.48
- Total Volume: $62,637.83
- 24h Volume: $1,101.44
- Open Interest: $19,775.61

- Expiration: August 1, 2026

## Market Behavior & Price Dynamics

This market has experienced a significant round trip, starting and ending at a 14.0% probability for a "YES" resolution. For much of its history, the price demonstrated a sideways trend, establishing a support level in the 11-14% range. The market's probability peaked at 68.0% before a dramatic and decisive price movement. On May 23, 2026, the price collapsed by 53 percentage points, falling from 68.0% to 15.0%. This sharp decline was reportedly driven by skepticism from a majority of Supreme Court justices during oral arguments regarding the constitutionality of the federal gun ban for marijuana users.

The price action suggests a major shift in market sentiment. The initial climb to 68.0% indicated growing belief that the court would uphold the ban. However, the subsequent crash following the oral arguments indicates a complete reversal of this sentiment. The market now overwhelmingly predicts that the ban will be struck down, reflected in the current low price of 14.0%. A significant volume of 231.41 contracts traded on May 27, after the price drop, suggests strong conviction from traders at this new, lower probability. The previous peak of 68.0% now stands as a strong resistance level, while the 11-14% range has been re-established as a firm support base.

## Significant Price Movements

#### 📉 May 23, 2026: 53.0pp drop

Price decreased from 68.0% to 15.0%

**Outcome:** Before 2026

**What happened:** The primary driver of the 53.0 percentage point drop in the prediction market was the skepticism expressed by a majority of Supreme Court justices during oral arguments in *United States v. Hemani* on March 2, 2026 [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/). Justices questioned the constitutionality of the federal gun ban for marijuana users, particularly when not shown to be impaired, which strongly indicated a potential ruling against upholding the ban [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/). While this key development occurred in March, its implications for the market could have been fully integrated or reinforced by ongoing analysis, leading to the significant price movement on May 23, 2026. No social media activity was identified as leading, coinciding, or lagging the price move, making social media irrelevant based on the provided sources.

## Contract Snapshot

The market resolves to "Yes" if the Supreme Court, in *United States v. Hemani*, issues a decision upholding the federal ban on firearm possession for marijuana users (18 U.S.C. § 922(g)(3)) by reversing or overturning the Fifth Circuit’s decision. If the Supreme Court does not issue such a decision upholding the ban by August 1, 2026, the market will resolve to "No" and close. The outcome will be verified from supremecourt.gov, and the market will close early if the decision occurs before the final deadline.

## Market Discussion

Traders are split on whether the Supreme Court will uphold the federal gun ban for marijuana users, though the market's pricing heavily favors "No." Arguments for "No" suggest the ban fails the *Bruen* historical tradition test, that marijuana users are no more dangerous than alcohol drinkers, and that oral arguments point to a narrowing of 922(g)(3). Those predicting "Yes" believe liberal justices, potentially joined by others, will prioritize firearms regulation and consider the historical context of "unlawful users."

## Market Data

| Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest |

| Before 2026 | 15% | 16% | 14% | $62,637.83 | $19,775.61 |

## How might the Supreme Court's 'historical tradition' test from the *Bruen* decision be applied in *United States v. Hemani*?

**The Supreme Court evaluates a federal gun law under the Bruen test**

The Supreme Court evaluates a federal gun law under the Bruen test. In United States v. Hemani, the Court is applying the "historical tradition" test derived from the Bruen decision to assess a federal law, 18 U.S.C. § 922(g)(3) [[^]](https://www.scotusblog.com/2026/03/the-how-and-why-of-gun-control/)[[^]](https://www.independent.org/article/2026/03/04/oral-argument-in-hemani/)[[^]](https://rockinst.org/blog/guns-ganja-and-gavels-five-things-to-watch-for-in-the-supreme-courts-us-v-hemani-oral-arguments/)[[^]](https://www.vox.com/policy/481254/supreme-court-hemani-marijuana-guns-second-amendment). This statute prohibits "unlawful users" of controlled substances, including marijuana, from possessing firearms. The central question is whether this prohibition aligns with historical gun regulations or if it represents an unjustified categorical ban based on status [[^]](https://www.scotusblog.com/2026/03/the-how-and-why-of-gun-control/)[[^]](https://www.independent.org/article/2026/03/04/oral-argument-in-hemani/)[[^]](https://rockinst.org/blog/guns-ganja-and-gavels-five-things-to-watch-for-in-the-supreme-courts-us-v-hemani-oral-arguments/)[[^]](https://www.vox.com/policy/481254/supreme-court-hemani-marijuana-guns-second-amendment). Hemani's argument is that this federal law lacks a historical tradition for such a broad prohibition [[^]](https://www.scotusblog.com/2026/02/court-to-hear-argument-on-whether-and-when-drug-users-may-possess-firearms/)[[^]](https://www.law.cornell.edu/supct/cert/24-1234)[[^]](https://constitutioncenter.org/blog/supreme-court-to-consider-legality-of-gun-bans-for-marijuana-users)[[^]](https://www.scotusblog.com/2026/03/the-how-and-why-of-gun-control/)[[^]](https://www.independent.org/article/2026/03/04/oral-argument-in-hemani/)[[^]](https://rockinst.org/blog/guns-ganja-and-gavels-five-things-to-watch-for-in-the-supreme-courts-us-v-hemani-oral-arguments/). Conversely, the government asserts that the prohibition is consistent with historical regulations designed to prevent dangerous individuals from possessing firearms [[^]](https://www.scotusblog.com/2026/03/the-how-and-why-of-gun-control/)[[^]](https://www.independent.org/article/2026/03/04/oral-argument-in-hemani/)[[^]](https://rockinst.org/blog/guns-ganja-and-gavels-five-things-to-watch-for-in-the-supreme-courts-us-v-hemani-oral-arguments/)[[^]](https://www.vox.com/policy/481254/supreme-court-hemani-marijuana-guns-second-amendment).

Oral arguments suggest the Court views the federal law skeptically. Following oral arguments in March 2026, observers noted that a majority of the Supreme Court appeared to be skeptical of the federal law's application to individuals in Hemani's situation [[^]](https://www.vox.com/policy/481254/supreme-court-hemani-marijuana-guns-second-amendment)[[^]](https://thereload.com/analysis-the-path-for-the-government-to-win-scotus-weed-and-guns-case-member-exclusive/). This indicates a potential ruling in favor of the defendant, which could lead to the statute being narrowed or limited on Second Amendment grounds [[^]](https://www.vox.com/policy/481254/supreme-court-hemani-marijuana-guns-second-amendment)[[^]](https://thereload.com/analysis-the-path-for-the-government-to-win-scotus-weed-and-guns-case-member-exclusive/).

## What historical evidence does the Department of Justice cite to support a founding-era tradition of disarming individuals deemed dangerous, and how has it been challenged?

DOJ Basis for Gun Bans | Historical traditions of disarming dangerous individuals, especially post-Bruen decision [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.lawfaremedia.org/article/rahimi-second-amendment-originalism-and-the-disarming-of-loyalists-during-the-american-revolution)[[^]](https://drexel.edu/law/lawreview/issues/Archives/v16-1/greenlee/)[[^]](https://firearmslaw.duke.edu/2024/10/historical-context-weapons-laws-and-early-american-governance) |
DOJ Stance on Drug Users | Habitual illegal drug users with firearms pose "unique dangers to society" [[^]](https://www.theindianalawyer.com/articles/a-supreme-court-case-over-whether-marijuana-users-can-own-guns-is-creating-unusual-alliances)[[^]](https://www.marijuanamoment.net/federal-marijuana-rescheduling-shouldnt-impact-case-on-gun-rights-for-users-trump-doj-says-in-supreme-court-filing/) |
SCOTUS Skepticism | Justices questioned historical analogues for marijuana users and the claim of their dangerousness [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.courthousenews.com/disarming-of-drug-users-leaves-justices-dazed/)[[^]](https://www.latimes.com/politics/story/2026-03-02/supreme-court-questions-denying-gun-rights-to-marijuana-users-in-test-of-2nd-amendment) |

**The Department of Justice (DOJ) supports gun bans by citing historical disarmament traditions**

The Department of Justice (DOJ) supports gun bans by citing historical disarmament traditions. Following the Supreme Court's 2022 *Bruen* decision, which mandates alignment with historical firearm regulation, the DOJ largely supports federal gun bans by referencing historical traditions of disarming individuals deemed dangerous [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.lawfaremedia.org/article/rahimi-second-amendment-originalism-and-the-disarming-of-loyalists-during-the-american-revolution)[[^]](https://drexel.edu/law/lawreview/issues/Archives/v16-1/greenlee/)[[^]](https://firearmslaw.duke.edu/2024/10/historical-context-weapons-laws-and-early-american-governance). The DOJ specifically contends that habitual illegal drug users who possess firearms pose "unique dangers to society" [[^]](https://www.theindianalawyer.com/articles/a-supreme-court-case-over-whether-marijuana-users-can-own-guns-is-creating-unusual-alliances)[[^]](https://www.marijuanamoment.net/federal-marijuana-rescheduling-shouldnt-impact-case-on-gun-rights-for-users-trump-doj-says-in-supreme-court-filing/). For example, in the *Hemani* case, the Trump administration, representing the DOJ, argued that colonial and founding-era laws prohibiting "habitual drunkards" from possessing firearms serve as a historical analogue for disarming habitual drug users [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.courthousenews.com/disarming-of-drug-users-leaves-justices-dazed/). The government also points to early Republic efforts, such as the disarming of Loyalists, slaves, freedmen, and Native Americans, as evidence that legislatures have historically disarmed individuals "who could not be trusted with firearms" [[^]](https://www.lawfaremedia.org/article/rahimi-second-amendment-originalism-and-the-disarming-of-loyalists-during-the-american-revolution)[[^]](https://scholarship.law.umn.edu/cgi/viewcontent.cgi?article=1022&context=mlr-headnotes)[[^]](https://scholarship.law.uwyo.edu/cgi/viewcontent.cgi?article=1434&context=wlr).

Challenges frequently question the historical analogues' sufficiency under *Bruen*. Opponents of the DOJ's historical arguments often question whether the cited historical examples are sufficiently analogous to modern regulations under the *Bruen* test, which requires a "representative historical analogue" [[^]](https://www.lawfaremedia.org/article/rahimi-second-amendment-originalism-and-the-disarming-of-loyalists-during-the-american-revolution). During the *Hemani* case, several Supreme Court justices from across the ideological spectrum voiced skepticism regarding the DOJ's historical arguments [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.latimes.com/politics/story/2026-03-02/supreme-court-questions-denying-gun-rights-to-marijuana-users-in-test-of-2nd-amendment)[[^]](https://www.courthousenews.com/disarming-of-drug-users-leaves-justices-dazed/). Justices questioned the validity of comparing historical prohibitions on "habitual drunkards" with contemporary bans on marijuana users, particularly concerning the actual dangerousness posed by occasional marijuana use [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.courthousenews.com/disarming-of-drug-users-leaves-justices-dazed/). Justice Amy Coney Barrett, for instance, questioned the government's evidence that using marijuana a few times a week makes someone dangerous, and Justice Ketanji Brown Jackson suggested the firearm ban for cannabis users might lack the necessary historical roots under the *Bruen* test [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.latimes.com/politics/story/2026-03-02/supreme-court-questions-denying-gun-rights-to-marijuana-users-in-test-of-2nd-amendment). Justice Sonia Sotomayor also raised concerns about the potential vagueness of the term "unlawful user" [[^]](https://www.courthousenews.com/disarming-of-drug-users-leaves-justices-dazed/).

Critics argue many historical disarmament laws were discriminatory and inappropriate. Further criticisms contend that many historical disarmament laws, which targeted groups such as Loyalists, Black individuals, enslaved people, and Native Americans, were discriminatory and therefore cannot establish legitimate historical traditions for modern gun regulations [[^]](https://scholarship.law.umn.edu/cgi/viewcontent.cgi?article=1022&context=mlr-headnotes)[[^]](https://scholarship.law.uwyo.edu/cgi/viewcontent.cgi?article=1434&context=wlr). Some challenges maintain that there is no historical tradition of disarming peaceable citizens and that prohibitions should be limited to individuals who are genuinely violent or dangerous [[^]](https://scholarship.law.uwyo.edu/cgi/viewcontent.cgi?article=1434&context=wlr). In a relevant case, the Third Circuit Court of Appeals, while initially considering whether the historical standard was "disrespect for the rule of law" rather than "dangerousness," ultimately found a federal gun ban unconstitutional for a nonviolent misdemeanor conviction, indicating the government failed to historically justify disarming the individual [[^]](https://drexel.edu/law/lawreview/issues/Archives/v16-1/greenlee/).

## How does the Department of Justice's argument likening marijuana users to historical 'habitual drunkards' compare with the respondent's counter-arguments?

DOJ's Historical Analogue | founding-era habitual-drunkard laws [[^]](https://thereload.com/analysis-how-the-trump-administration-plans-to-defend-the-gun-ban-for-weed-users-at-scotus-member-exclusive/) |
DOJ's Statute Characterization | temporary disarmament and a lesser restriction [[^]](https://thereload.com/analysis-how-the-trump-administration-plans-to-defend-the-gun-ban-for-weed-users-at-scotus-member-exclusive/) |
Hemani's Core Argument | No historical tradition for stripping gun rights from 'a few times a week' marijuana users [[^]](https://www.supremecourt.gov/DocketPDF/24/24-1234/392632/20260123152824381_24-1234%20Brief%20for%20Respondent.pdf) |

**The Department of Justice (DOJ) likens the gun ban for marijuana users to historical laws**

The Department of Justice (DOJ) likens the gun ban for marijuana users to historical laws. The DOJ argues that the federal prohibition on firearm possession for marijuana users is "relevantly similar" to "founding-era habitual-drunkard" laws [[^]](https://thereload.com/analysis-how-the-trump-administration-plans-to-defend-the-gun-ban-for-weed-users-at-scotus-member-exclusive/). The department characterizes the statute's effect as a "temporary disarmament" during periods of habitual use, viewing it as a "lesser restriction" compared to other prohibitions [[^]](https://thereload.com/analysis-how-the-trump-administration-plans-to-defend-the-gun-ban-for-weed-users-at-scotus-member-exclusive/).

Conversely, Respondent Hemani challenges historical grounds for stripping gun rights from marijuana users. Hemani contends that no historical tradition supports revoking gun rights from individuals who consume marijuana "a few times a week" for self-defense [[^]](https://www.supremecourt.gov/DocketPDF/24/24-1234/392632/20260123152824381_24-**1234%**20Brief%20for%20Respondent.pdf). Hemani's brief specifies that the case is limited to the "unlawful user" prong, focusing solely on the constitutionality of §922(g)(3) as applied to the respondent [[^]](https://www.supremecourt.gov/DocketPDF/24/24-1234/392632/20260123152824381_24-**1234%**20Brief%20for%20Respondent.pdf).

## What specific statements from Justices Gorsuch, Barrett, and Jackson during oral arguments indicated skepticism of the federal government's position?

Justice Barrett's Question | "What is the government’s evidence that using marijuana a couple of times a week makes someone dangerous?" [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/) |
Justice Gorsuch's Challenge | Questioned whether figures like John Adams, James Madison, and Thomas Jefferson would be disarmed for life as "habitual drunkards" [[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/)[[^]](https://www.yahoo.com/news/articles/gorsuch-name-checks-founding-fathers-154432065.html) |
Justice Jackson's Legal Stance | Bruen framework prohibits crediting "the judgments of the modern legislature about who is dangerous and who needs to be disarmed" [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://ballsandstrikes.org/scotus/us-v-hemani-second-amendment-silliness/) |

**Justices Gorsuch and Barrett expressed skepticism of the federal government's position**

Justices Gorsuch and Barrett expressed skepticism of the federal government's position. During oral arguments in U.S. v. Hemani on March 2, 2026, Justices Neil Gorsuch and Amy Coney Barrett raised concerns about the federal government’s stance on gun bans for marijuana users [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/). Justice Barrett specifically questioned the lack of evidence linking marijuana use to dangerousness, asking for proof that using marijuana a couple of times a week makes someone a danger [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/). Justice Gorsuch noted the federal government's "conflicted" position regarding marijuana, as it is "sort of illegal and sort of isn’t" [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/). He further challenged the historical "habitual drunkard" analogy, inquiring whether founding-era figures would be disarmed under the government's presented theory [[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://www.cbsnews.com/news/supreme-court-could-loosen-law-barring-marijuana-users-from-owning-guns/)[[^]](https://www.yahoo.com/news/articles/gorsuch-name-checks-founding-fathers-154432065.html).

Justice Jackson questioned reliance on modern legislative judgments for disarmament. Justice Ketanji Brown Jackson contributed to the skepticism by challenging the federal government’s use of modern legislative judgments [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms). She stated that the Bruen framework prevents crediting "the judgments of the modern legislature about who is dangerous and who needs to be disarmed" [[^]](https://www.pbs.org/newshour/politics/listen-live-supreme-court-considers-whether-marijuana-and-other-drug-users-may-possess-firearms)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://ballsandstrikes.org/scotus/us-v-hemani-second-amendment-silliness/).

**Ideologically diverse groups challenged the federal gun ban for marijuana users**

Ideologically diverse groups challenged the federal gun ban for marijuana users. An alliance comprising the ACLU, NRA, and NORML submitted amicus briefs arguing that the federal gun ban for marijuana users lacks historical precedent, violates the Second Amendment, and is unconstitutionally vague [[^]](https://www.kgw.com/article/news/nation-world/supreme-court-marijuana-cannabis-use-gun-ownership/507-d0dc11ee-79c7-44f1-b25c-db41029e7045)[[^]](https://reason.com/2026/02/02/the-nra-and-norml-unite-to-oppose-the-federal-gun-ban-for-marijuana-users/)[[^]](https://www.nraila.org/articles/20260130/nra-files-amicus-brief-urging-supreme-court-to-strike-down-firearm-prohibition-for-marijuana-users)[[^]](https://www.facebook.com/Reason.Magazine/posts/the-aclu-long-leery-of-the-second-amendment-has-joined-the-nra-in-urging-scotus-/1299337208730074/). During a hearing for United States v. Hemani on March 2, 2026, the Supreme Court appeared skeptical of the federal law (18 U.S.C. § 922(g)(3)) [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://www.youtube.com/watch?v=DJxAA6OtdCo). A majority of justices signaled that the law, which broadly prohibits marijuana users from possessing firearms, may be unconstitutionally broad, particularly as it applies to non-intoxicated individuals [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/)[[^]](https://www.youtube.com/watch?v=DJxAA6OtdCo).

The Supreme Court is expected to narrow the gun ban's application. Analysts predict that the Supreme Court will issue a ruling by late June 2026, which is projected to narrow the government's authority to enforce the ban [[^]](https://www.carolinaattorneys.com/blog/amp/supreme-court-marijuana-gun-rights-prediction-2026/). This decision is anticipated to preserve the statute rather than striking it down entirely, possibly by requiring evidence of active impairment or specific dangerousness [[^]](https://www.carolinaattorneys.com/blog/amp/supreme-court-marijuana-gun-rights-prediction-2026/). This foreseen "middle-ground" ruling would uphold the statute but impose significant limitations on its application [[^]](https://predictions.io/event/kalshi/KXSCOTUSMARIJUANAGUN)[[^]](https://www.coinbase.com/en-ca/predictions/event/KXSCOTUSMARIJUANAGUN).

## What Could Change the Odds

**The Supreme Court is currently considering the constitutionality of 18 U.S.C.** § 922(g)(3), a federal law banning firearms possession by 'unlawful users' of controlled substances, in the case United States v. Hemani. Oral arguments were held on March 2, 2026, with the Court appearing skeptical of the law's broad application to marijuana users [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.thetrace.org/2026/03/scotus-drug-use-gun-ban-hemani-arguments/)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/). A ruling in United States v. Hemani is expected by late June or early July 2026. The decision will determine whether the federal government can enforce this categorical gun ban against marijuana users who were not shown to be under the influence at the time of firearm possession [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.thetrace.org/2026/03/scotus-drug-use-gun-ban-hemani-arguments/)[[^]](https://www.scotusblog.com/2026/03/supreme-court-skeptical-of-law-banning-drug-users-from-possessing-firearms/).

**While market analysts and legal experts expect the government to face significant limitations in its enforcement power, many predict the Court will ultimately choose to refine or narrowly uphold the law rather than completely dismantle it [[^]](https://www.cnn.com/2026/03/02/politics/supreme-court-signals-it-will-back-marijuana-user-who-was-charged-with-owning-a-gun)[[^]](https://www.carolinaattorneys.com/blog/supreme-court-marijuana-gun-rights-prediction-2026/).** The legal landscape is further complicated by the Trump administration's ongoing efforts to reschedule marijuana to Schedule III, though the Department of Justice has stated this move should not alter its position in the Hemani case [[^]](https://www.cannabisbusinesstimes.com/cannabis-rescheduling/news/15826182/3-states-challenge-trump-dojs-schedule-iii-cannabis-rule).
