How much can an adult possess?
Age 21+: 2.5 oz plant material and 15 g extract.
Ohio limits cumulative adult-use and homegrown possession to 2.5 ounces of plant material and 15 grams of extract. Lawfully cultivated seeds, live plants, and clones are excluded from the plant-material weight limit.
Keep in mind: Purchased and homegrown amounts are not separate allowances. There is no general larger harvested-cannabis allowance for home storage under these provisions. Cannabis must comply with licensed-dispensary, homegrow, and authorized-transfer rules.
Can I grow at home?
6 plants per adult; 12 total at the primary residence.
Adults 21+ may grow up to 6 plants each, with 12 per residence. Growing must be at the primary residence in a secured enclosed area that prevents under-21 access and is not visible from public space by normal unaided vision.
Keep in mind: Growing is prohibited where a rental agreement bans it and at specified child-care and transitional or correctional residences. Growing for another person and selling homegrown marijuana are not authorized.
Can I consume in public?
Public-place consumption is prohibited; smoking and vaping have narrower location rules.
Ohio prohibits adult-use and homegrown consumption in a statutory public place. Smoking, combustion, and vaping are permitted only on privately owned property used primarily for residential or agricultural purposes, subject to additional exclusions.
Keep in mind: Prohibited leases, specified child-care or transitional residences, public places, and workplaces remain excluded. The statutory public-place definition covers enclosed areas open to the public, not private residences; separate smoking and vaping restrictions also apply outdoors.
