Growing cannabis for personal use is legal in about two dozen US states for adults 21 and older, but it remains a federal crime and stays fully illegal in roughly half the country. Every state that permits a home grow also caps plant counts, requires privacy and security, and forbids unlicensed sales. Your location, your age, and your medical status decide whether you can legally grow at home.

Is growing cannabis for personal use legal in the United States?

Legality depends on state law, not federal law. Cannabis is still a Schedule I controlled substance under the federal Controlled Substances Act, so cultivation is a federal offense even in states that allow a small personal grow.

Other states allow cultivation only for registered medical patients. Illinois, Hawaii, Oklahoma, and New Hampshire all permit patient grows while restricting recreational home grow.

How many plants can you grow at home?

Plant limits vary widely, and most states count plants per household rather than per person. Common state limits include:

Where is growing cannabis for personal use still illegal?

Idaho, Kansas, South Carolina, Wyoming, Tennessee, and Indiana prohibit cannabis entirely, including home cultivation. Legal states such as Washington, New Jersey, Illinois (recreational), Florida, Pennsylvania, and Georgia allow sales or medical use but no personal grow.

Does federal law allow home growing?

No. Federal penalties for cultivation scale with plant count and can include prison time for large grows. Small personal grows are rarely prosecuted federally, but national parks, federal land, and federally subsidized housing carry real risk.

What rules apply beyond plant counts?

Can I sell or ship extra cannabis?

No. Every home grow state bans unlicensed sales, and moving cannabis across state lines is a federal offense regardless of the states involved. Extra harvest can usually only be shared as a free gift within state limits.

Frequently asked questions

Can my landlord ban growing cannabis?

Yes. Private landlords and HOAs can prohibit cultivation in a lease or bylaws, and many do. State legalization does not override a private property agreement.

Can I grow cannabis in an apartment?

Only if the lease and building rules allow it and the grow meets state and local requirements. Rental policies, HOA rules, and property management decisions often prohibit it.

Do medical patients get higher plant limits?

Often yes. Registered patients in states like Illinois, Hawaii, Oklahoma, and New Hampshire may grow more plants than recreational users, and some states allow patient grows where recreational home grow is banned.

Because plant counts, possession caps, and local rules change often, confirm your state statute and city ordinance before starting a grow.
