For adults 21 and older, the buying decision starts with legality, not convenience. You can purchase cannabis only in a state that allows adult-use sales and only from a licensed shop or delivery service. Once you confirm that, convenience often decides where you buy: a nearby dispensary, a delivery option, or a curbside pickup. But convenience should never override testing, possession limits, or age verification.
Where cannabis is legal for adults 21: the short answer
As of 2024, 24 states and the District of Columbia allow adults 21 and older to buy cannabis for recreational use. The list includes Alaska, Arizona, California, Colorado, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada, New Jersey, New Mexico, New York, Ohio, Oregon, Rhode Island, Vermont, Virginia, and Washington. But state law does not make cannabis legal everywhere. You still need to buy from a licensed retailer, stay within possession limits, and keep your purchase inside the state.

What to look for before you buy
- State adult-use status: Confirm the state has legalized recreational sales, not just medical cannabis.
- Age verification: You need a government ID showing you are 21 or older.
- Licensed retailer: Buy only from state-licensed dispensaries or delivery services. Unlicensed sellers are illegal and unsafe.
- Possession limits: Each state sets a maximum amount you can carry or buy at once. Common limits are 1 to 2 ounces of flower or its equivalent in concentrates and edibles.
- Product testing: Licensed products carry lab results for potency, pesticides, and mold. Ask for them.
- Taxes and fees: State and local taxes apply at checkout. The final price can differ from the shelf price.

Common pitfalls
- Assuming federal legality: Cannabis remains illegal under federal law. Crossing state lines with it is a federal crime.
- Buying from unlicensed sources: These products skip testing and can contain pesticides or heavy metals.
- Ignoring possession limits: Buying more than the legal limit can lead to fines or arrest.
- Using a fake ID: Retailers scan IDs. A fake ID means no sale and possible legal trouble.
- Forgetting local bans: Some cities and counties ban recreational sales even if the state allows them.
