Cannabis Laws by State — Home Grow Map

Where cannabis is legal in the United States, and — the question this site exists for — where you may legally grow it at home. Every state below was checked against official state sources in October 2026, and every row links to its proof.

The short version (checked October 22, 2026): recreational cannabis is legal in 24 states and Washington, D.C.; medical programs operate in 40 states and D.C.; 9 states allow only limited low-THC/CBD access; and Idaho has no program at all. Home growing is allowed for adults in 21 jurisdictions and for registered medical patients only in 5 more.

Tap or click a state tile to jump to its row. Colors show the overall status — but home grow is its own column in the table, because some recreational states (New Jersey, Washington, Delaware) still prohibit growing at home, and some medical states allow patients to grow.

How to read this page (and how we checked it)

Recreational legal — adults 21+ may possess and use cannabis under state law.
Medical only — a state-run medical program exists; recreational use is not legal.
Limited low-THC/CBD only — no comprehensive medical program, but state law provides a narrow channel for low-THC/CBD products (a statutory carve-out, defense, or trial access). These are not medical programs, and the notes say so.
No program — illegal — cannabis remains illegal under state law (Idaho).

Each row was compiled from the official sources linked in its Sources cell — state cannabis regulators, state program pages, and statute text — and cross-checked against national trackers (NCSL, MPP, NORML). Where sources disagreed, we followed the official state source. Plant counts are summaries of the cited law; conditions (locked enclosures, visibility, registration cards, distance rules) live in the notes and in the sources themselves.

This page is a summary, not legal advice. Cannabis also remains illegal under federal law, and city, county, landlord, HOA, employer and federal-housing rules can be stricter than state law. Before you order seeds or plant anything, open your state's official source and confirm the current rules. Laws change — this page was last fully checked on October 22, 2026.

Indiana	Limited low-THC/CBD only	No	— No medical program, registry or dispensaries — marijuana is illegal in Indiana.

Kansas	Limited low-THC/CBD only	No	— No medical or recreational program. The only carve-out is Claire and Lola's Law (K.S.A. 65-6235): a narrow affirmative defense for cannabidiol oil with THC no more than 5% relative to CBD for a debilitating medical condition, and the statute expressly does not allow any other form of cannabis.	kslegislature.gov:443
