There is no single national limit for how much weed you can legally carry. In most US states with legal recreational cannabis, adults 21 and older may carry up to 1 ounce (28.5 grams) of flower in public. But states like New York allow 3 ounces, Maine allows 2.5 ounces, and medical patients often can carry more. If convenience shapes your purchase, choose formats that match your state's carry limit, such as pre-rolled joints, vape cartridges, or single-serve edibles.

What to look for before you carry

Start with your state's possession law, not the store's menu. Recreational and medical limits differ. Public carry limits can be lower than what you may store at home. Check whether your state measures limits by weight or by THC content. Also confirm if your product must stay in its original sealed package while you travel.

  • Driving with an open container of cannabis can lead to a DUI charge.
