California peace officers now stand at the intersection of two bodies of law that pull in opposite directions. State law shields their right to use cannabis when they are not on duty, while federal law forbids anyone who uses cannabis from possessing the very firearm that their profession demands. The Supreme Court has just unsettled the federal side of that equation in United States v. Hemani, and its decision invites a fresh look at whether an officer who lawfully uses cannabis away from work may still be denied the badge and the gun. United States v. Hemani, 146 S. Ct. 1677 (2026) The answer is not yet clear, and the competing arguments deserve careful attention.
The Legislature
spoke plainly when it enacted Assembly Bill 2188 and Senate Bill 700, which
amended Government Code section 12954 and took effect on January 1, 2024. That
statute makes it an unlawful employment practice for an employer to penalize a
worker for using cannabis off the job and away from the workplace, and it
forbids reliance on a drug test that detects only the nonpsychoactive cannabis
metabolites that linger in the body long after any effect has passed. Gov Code § 12954. The Legislature exempted only employees in the building and
construction trades, and it said nothing at all about peace officers. Because
the Legislature expressly excluded one occupation and left every other
unmentioned, officers possess a legitimate argument that the omission of their
profession was deliberate and that the new protection reaches them. The statute
therefore begins from a position that appears to favor the officer who uses
cannabis on personal time.
That favorable
starting point gives way, however, to several exemptions that may prove
decisive for law enforcement. Section 12954 does not permit an employee to use
or to be impaired by cannabis on the job, it preserves an employer's authority
to maintain a drug free workplace, and it expressly leaves intact any other
rights or obligations that state or federal law places on the employer. The
statute also declines to preempt any state or federal law that requires
controlled substance testing as a condition of employment, and it removes from
its protection any position that requires a federal government background
investigation or security clearance. The difficulty is that the ordinary
municipal or county officer completes a state background investigation for good
moral character under Government Code section 1031, not the federal
investigation that the exemption describes, and Government Code section 1029
disqualifies only those convicted of a felony rather than those who use
cannabis. Whether these provisions carve officers out of the statute or leave
them comfortably within it remains genuinely uncertain.
The sharpest
tension arises not from the employment statute but from the firearm that every
sworn officer must carry. Federal law makes it unlawful for any person who is
an unlawful user of a controlled substance to possess a firearm, and cannabis
remains a Schedule I controlled substance under federal law no matter how
completely California has legalized it. An officer who uses cannabis therefore
appears, at least on the face of the statute, to be a person whom Congress has
forbidden to hold a tool that the job requires. That same officer who buys a
personal weapon must attest truthfully on the federal firearms transaction
record that he is not an unlawful user of marijuana, and a false answer carries
federal criminal exposure. The firearm requirement, far more than anything in
the employment code, is what has long threatened to place cannabis-using
officers outside the protection that Assembly Bill 2188 seems to promise.
For years the
governing federal authority in California cut sharply against the officer. The
Ninth Circuit in Wilson v. Lynch, 835 F.3d 1083 (9th Cir. 2016) applied
a two-step inquiry and intermediate scrutiny and upheld the federal
restrictions that keep marijuana users, including the holders of a state
medical marijuana card, from acquiring firearms. The court reasoned that these
laws burden the Second Amendment only minimally and incidentally, and it
concluded that the Constitution tolerates such modest collateral burdens. Wilson
supplied a straightforward answer that a cannabis user could be kept from the
firearm and therefore from the job. That answer, however, rested on the Ninth
Circuit’s Second Amendment analysis that the Supreme Court has rejected.
The ground shifted
when the Supreme Court decided New York State Rifle and Pistol Association
v. Bruen and directed courts to measure firearm regulations against the
Nation's historical tradition rather than against tiers of scrutiny. United
States v. Hemani, 146 S. Ct. 1677 (2026), decided on June 18, 2026, applied
that framework to the very statute at issue here. Ali Hemani used marijuana a
few times a week, and the government sought to imprison and permanently disarm
him on that basis alone, without any claim that he was an addict, that he was
intoxicated while armed, or that he had ever posed a danger to anyone. The
Court held that the prosecution could not stand, because the historical laws
the government invoked, the old regimes that restrained habitual drunkards
through vagrancy, civil commitment, and surety bonds, targeted persons whose
intoxication left them incapacitated and operated only after some form of legal
process. Section 922(g)(3), by contrast, automatically disarms any regular user
of any controlled substance without proof of incapacity, intoxication, or
dangerousness, and the Court concluded that this automatic and status driven
ban does not fit within the Nation's historical tradition of firearm
regulation. Applying the statute to Hemani on those facts therefore violated
the Second Amendment.
The Court took
evident care to confine its ruling. It did not decide whether Congress may
disarm those who are addicted or presently intoxicated, it did not disturb the
separate prohibition on firearm possession by convicted felons, and, most
importantly for officers, it did not resolve whether the government may proceed
under the statute when it offers individualized proof that a person's drug use
renders him a danger to himself or others. The holding thus dismantles one
categorical justification for disarming cannabis users while expressly
preserving room for a narrower approach that rests on individualized findings.
Arguably, if the
federal firearm ban cannot constitutionally reach a person merely because he
uses cannabis, then an agency can no longer prohibit marijuana use based on the
contention that such an officer is legally incapable of possessing their duty
weapon. Under this argument, the exemptions from section 12954 may not apply,
because they preserve only employer obligations that federal law genuinely
imposes, and under Hemani federal law may not impose a firearm
disability based on cannabis use alone. The earlier Ninth Circuit rule in Wilson,
resting on a repudiated legal framework, looks increasingly invalid after Hemani.
Thus, an officer disciplined solely because he or she uses cannabis may run
afoul of the categorical prohibition that the Supreme Court has now rejected.
Read together, Assembly Bill 2188 and Hemani suggest the officer may be protected
from discipline.
However, the application
of Assembly Bill 2188 to peace officers remains unclear. Hemani decided
only an as applied challenge that turned on the complete absence of any
individualized showing, and the Court pointedly left open a prosecution
supported by individualized proof of dangerousness. An agency may contend that
an officer who carries a loaded firearm in public every single day presents
exactly the individualized safety concern that the Court declined to reach, so
that the reasoning of Hemani may provide officers no shelter at all.
Section 12954
independently preserves the employer's right to maintain a drug free workplace
and to honor any obligation that federal law and regulation impose, and
Government Code section 1031 must be read and applied consistently with federal
law. Cannabis also remains unlawful under federal law even where a prosecution
under section 922(g)(3) would fail, and the officer who purchases a personal
firearm still confronts the sworn federal form and the criminal exposure that a
false answer invites. 18 U.S.C.A. § 922. Wilson, while legally suspect,
remains binding in the Ninth Circuit until that appellate court or the Supreme
Court squarely overrules it, and an agency may reasonably continue to rely upon
it.
The
honest conclusion is that the law has not settled and that officers and their
employers alike should proceed with caution. Hemani has weakened the
categorical federal bar that once made this analysis simple, yet it has
deliberately left open the individualized path to enforcement. More importantly,
the California exemptions remain untested in any court.
Public safety unions should resist any suggestion that their members must surrender the protections that the Legislature extended, and they should insist that any adverse action rest on an individualized assessment of fitness and risk rather than on cannabis using status alone. Officers, for their part, should remember that cannabis remains unlawful under federal law and should weigh that stubborn reality before they place their careers in the hands of an unsettled disciplinary dispute. Until the Legislature or the courts clarify this issue, prudent officers should tread lightly regarding off-duty cannabis use.
