Recreational Cannabis: 21+ Age Limit
All states with legal recreational cannabis set the minimum age at 21 for purchase, possession, and consumption. This includes states like California, Colorado, Washington, and New York. You must present a valid government-issued ID, such as a driver's license or passport, to enter a dispensary or buy online for in-store pickup. Some states allow delivery to adults 21+ who show ID at the door.
Medical Cannabis: Age Limits Vary
Medical cannabis programs often have lower age limits. Many states allow patients as young as 18 to qualify with a medical card. For patients under 18, most states require a caregiver to register and purchase on their behalf. A few states set the medical age at 21, matching recreational rules. Always check your state's specific medical cannabis program rules for exact age requirements and caregiver provisions.
