The legal age for recreational cannabis is 21 in every U.S. state that allows adult use. No state sets a lower recreational age, and federal law still classifies cannabis as a Schedule I controlled substance. Convenience features like delivery, curbside pickup, and online ordering verify that a buyer is 21 and do not change the age requirement.
what is the legal age to buy cannabis
Which states allow recreational cannabis, and at what age?
As of 2025, 24 states and the District of Columbia allow adult-use cannabis, along with Guam, the Northern Mariana Islands, and the U.S. Virgin Islands. Each of those jurisdictions requires buyers and consumers to be at least 21 years old. A handful of additional states have legalized possession in limited amounts but not retail sales.
Cannabis Legal Age for Possession: 21 in Legal States
Does buying online or getting delivery change the legal age?
No. A dispensary must verify age at handoff even when the order was placed online. Delivery drivers check a government ID at the door before leaving the product.

Curbside pickup and drive-through lanes follow the same rule. Convenience shortens the trip, not the age gate.
Are medical cannabis age rules different?
Most medical states let patients 18 and older register on their own. Several states also permit minors to use medical cannabis with a caregiver or parental consent plus a physician's certification. Those allowances apply to medical programs only, never to recreational products.
What ID counts as proof of age?
- State-issued driver's license or non-driver ID card
- U.S. passport or passport card
- Military ID
- Tribal ID or foreign passport, accepted in some states
Expired IDs are routinely rejected. A vertical "under 21" license can still work after a customer turns 21, but budtenders may ask for a second form of ID.
What happens if you buy recreational cannabis under 21?
Penalties vary by state. Many jurisdictions issue a civil fine or require a diversion class for a first underage possession offense, and some add a driver's license suspension. Supplying cannabis to someone under 21 is a criminal offense in most legal states, even for a family member. Federal land, including national parks, stays off limits at any age.
Frequently asked questions
Is the legal age the same for edibles, vapes, and flower?
Yes. The 21-and-over rule covers every product type, including edibles, concentrates, topicals, and pre-rolls.
Can you buy cannabis at 18 in a medical-only state?
Only with a valid medical card in states whose medical age is 18. No state sells recreational cannabis to anyone under 21.
Can a parent buy cannabis for their adult child?
Not if the child is under 21. Giving recreational cannabis to a minor is illegal, aside from narrow medical caregiver provisions.
Does a college ID work at a dispensary?
Usually not. Most dispensaries require a government-issued photo ID that shows date of birth.
