People usually ask one question first: how much can I have? The answer changes at the state line, and in a few states the agency page, the statute and the governor's office give different numbers. We list what each source says instead of picking one quietly. Use the table, then open the state guide for the details.

Limits come from the state agency or statute named in each guide. Some sources are dated and are flagged there. This is not legal advice.
Where the Sources Disagree
- Virginia: the Code text and the Cannabis Control Authority FAQ show 2 ounces away from home, while 2021 materials and the governor's June 2026 release describe 1 ounce.
- Illinois: the compiled statute lists 60 grams for residents, but a state FAQ and the 2019 enacted text show 30 grams.
- California: the state health FAQ gives 8 grams of concentrate while a statute summary gives 4 grams.
- New Mexico: sources disagree on whether home storage is limited, and on whether public possession limits are on the state page.
- Missouri: the rule text says an adult cultivation card lasts 12 months, while the fee schedule says three years.
- Florida: a 35-day smokable order is capped at 2.5 ounces, while older materials cite a 4 ounce possession figure.
Where Adult Use Is Legal
Adults 21 and older can possess marijuana in Arizona, California, Colorado, Illinois, Massachusetts, Michigan, Missouri, New Jersey, New Mexico, New York, Ohio, Virginia. Virginia has no legal stores yet, and New Jersey does not allow home grow even though it sells legally.
Where It Is Still a Crime
Georgia treats one ounce or less as a misdemeanor with up to 12 months in jail and a fine of up to $1,000, and anything over an ounce as a felony. North Carolina makes half an ounce or less a Class 3 misdemeanor with any jail sentence suspended. Pennsylvania and Florida allow marijuana only through their medical programs.
Patient Limits
Medical programs set their own limits. Georgia caps certified patients at 12,000 mg of THC. Florida limits smokable orders by 35-day supply. Illinois lets its Opioid Alternative Patient Program patients buy 2.5 ounces every 14 days. Our card cost guide shows what each program charges.
