Can a landlord ban marijuana use, smoking, or home cultivation? State-by-state legal status, possession limits, and the federal Section 8 trap.
Cannabis remains a Schedule I controlled substance under the federal Controlled Substances Act, 21 U.S.C. § 812(c) Schedule I(c)(10), regardless of state legalization. Two consequences flow directly from this for every rental property in the United States:
As of 2026, 24 states + DC have legalized adult-use recreational cannabis, 14 additional states have comprehensive medical cannabis programs with smokable flower, 10 states have low-THC / CBD-only programs, and 1 state (Idaho) fully prohibits all cannabis. The table below sorts by legal tier (adult-use first), then by year of legalization. Click any state for landlord ban authority, possession and home-grow limits, medical-patient housing protections, and the full statute citation.

Because cannabis remains federal-illegal regardless of state law, landlords retain broad authority to control use on rental property. The following lease provisions are enforceable in every U.S. jurisdiction:
About a dozen states extend anti-discrimination housing protection to registered medical cannabis patients (AZ, AR, CT, DE, IL, MD, ME, MO, NV, NJ, NM, NY, OH, RI, VT, VA, WA, etc., varies by state). These protections never apply to federally subsidized housing (because of the HUD rule above), and most permit landlords to prohibit smoking. The protected activity is generally limited to off-premises use or non-smoking on-premises consumption (edibles, tinctures). State-by-state pages cite the exact statutory provision.
