Cannabis Purchase Limits: A Buyer's Guide
State law caps how much cannabis you can buy in one transaction. If you order more than the cap, the dispensary must cancel or reduce your order. The rules change by state, and they count flower, concentrates, and edibles on different scales. Check your state's limit before you build a cart.

Before You Order
- A valid government ID showing you are 21 or older (or 18+ with a medical card where allowed).
- Your state's current per-transaction purchase limit.
- Conversion rules for concentrates and edibles if you buy those products.
How to Stay Within Cannabis Purchase Limits
- Find your state's recreational or medical purchase cap. Most states list a per-transaction limit in ounces of flower. Colorado allows 1 ounce for recreational buyers and 2 ounces for medical patients. California sets 1 ounce of flower or 8 grams of concentrate. Washington allows 1 ounce of flower, 7 grams of concentrate, 16 ounces of solid edible, and 72 ounces of liquid edible.
- Convert concentrates and edibles to their flower equivalent. Many states count 1 gram of concentrate as equal to 3.5 grams of flower. For edibles, a common rule is 1 ounce of flower equals 800 milligrams of THC. Michigan, for example, caps recreational buyers at 2.5 ounces of flower or 15 grams of concentrate.
- Check for daily purchase caps. A few states limit how much you can buy in a single day, not just per transaction. Confirm whether your state tracks daily sales.
- Confirm residency rules if you are buying as a visitor. Arizona allows recreational buyers 1 ounce, but medical patients from other states may face different limits.
- Place your order within the cap. Online menus often let you add more than the limit to a cart, but the dispensary will adjust the order at checkout or cancel it.
Common Pitfalls
- Assuming limits are the same in every state. They are not. Oregon allows 1 ounce of flower, 5 grams of concentrate, and 16 ounces of edibles. Massachusetts allows 1 ounce of flower, 5 grams of concentrate, and 500 milligrams of THC in edibles.
- Mixing medical and recreational limits. If you hold a medical card, you may buy more, but the transaction must be rung as medical. You cannot combine both caps in one order.
- Ignoring the flower equivalent for vape carts. A 1-gram cartridge can count as 3.5 grams of flower in some states, which eats your cap fast.
- Forgetting that some states cap THC milligrams in edibles, not just weight. Colorado limits recreational edibles to 100 milligrams of THC per package.
What Happens If You Exceed the Limit
The dispensary will remove items until the order fits the legal cap. Some shops cancel the entire order. You may need to split the purchase across multiple days or visit a different state. Plan your cart around the lowest limit that applies to you.
