Massachusetts Cannabis Purchase and Possession Limits (2026 Update)

Massachusetts doubled its core cannabis limits in 2026. If you learned the rules before April, much of what you know about "one ounce" is out of date. Here are the current purchase and possession limits for adults 21+, how concentrates and edibles are converted, and how the limits apply to delivery orders.

Key takeaways

• Daily purchase limit: 2 ounces of flower, or the equivalent: 10 g of active THC in concentrates or 1,000 mg of active THC in edibles. It rose from 1 ounce on April 19, 2026.
• In public: up to 2 ounces (or the equivalent in products). At home: up to 10 ounces, plus your legal home harvest.
• Home grow: up to 6 plants per adult, 12 max per residence.
• Topicals don't count toward the daily sales limit.
• Delivery: one order per person per delivery, capped at 2 ounces or the equivalent, and one delivery per person per day.

What changed in April 2026

Chapter 65 of the Acts of 2026, signed April 19, 2026, amended the personal-use statute, M.G.L. chapter 94G, section 7. It raised the amount an adult 21+ may possess, use and purchase from one ounce to two ounces of marijuana, "or the equivalent amount of marijuana products." It also raised the amount you can give to another adult (without payment) to two ounces.

The CCC implemented the change the same day with Administrative Order No. 6, which set new sales limits and conversion standards for concentrates and edibles. Its Bulletin No. 1 told licensees to update their point-of-sale systems before April 20, 2026.

Daily purchase limits

Under the April 2026 administrative order, a retailer may not knowingly sell more than two ounces of marijuana, or its combined dry-weight equivalent in concentrates or edibles, to a customer per day, and no more than that per transaction.

Conversion standards

Concentrates and edibles are measured by active THC, not package weight. A 1-gram vape cartridge counts by the THC it actually contains, which is printed on the label and in its lab results.

The CCC's published conversion standards don't separately address products that combine flower and concentrate, such as infused pre-rolls. You don't need to work that out yourself: the limit is applied at checkout, as the next section explains.

Mixed carts

The limit is combined. If you buy some flower, a vape and an edible, each counts as its share of the two-ounce total. For example, one ounce of flower uses half the limit, leaving room for up to 5 g of active THC in concentrates or 500 mg of active THC in edibles, or a mix of the two. State rules require the point-of-sale system to block any transaction over the limit, so an order that goes over can't be completed. Browse by category: flower, pre-rolls, vapes, concentrates, edibles, tinctures and topicals.

Possession limits

Possession limits come from M.G.L. c. 94G, § 7, as amended in 2026.

Outside your home

Adults 21+ may possess 2 ounces or less of marijuana or the equivalent amount of marijuana products. The CCC's plain-language summary: "You may carry up to two ounces of marijuana."

The version of the statute in effect before April 19, 2026 capped concentrate within the one-ounce limit at 5 grams. The current text uses "the equivalent amount of marijuana products as determined by the commission" instead. The CCC's consumer FAQ now says you may carry up to two ounces, "except that not more than ten grams of marijuana may be in the form of marijuana concentrate." Until the Commission's Chapter 65 rules are final, treat 10 grams of concentrate as the ceiling within the two ounces you carry.

In your home

Within your primary residence, you may possess up to 10 ounces, plus any marijuana harvested from plants legally grown there.

Home cultivation

You may grow up to six plants for personal use, with no more than 12 plants at a residence with two or more adults.

Gifting

You may give up to two ounces (or the equivalent) to another adult 21+ without payment, as long as the transfer isn't advertised or promoted to the public. "Gifts" bundled with a paid purchase aren't gifts under the law.

How limits apply to cannabis delivery

Delivery has its own rules on top of the purchase limit, from 935 CMR 500.145:

• Order cap: a delivery business can't deliver more to a consumer than the personal possession amount under c. 94G, § 7(a)(1). An individual order may not exceed two ounces or its dry-weight equivalent.
• One order per delivery: only one individual order per consumer per delivery.
• Once per day: no more than one delivery to the same consumer at the same residence per calendar day.
• Delivered only to you: the order goes only to the consumer who placed it, after an ID check. See our ID requirements guide.

So you can't place two orders to get four ounces, and you can't get a second delivery later the same day. Plan your order to cover what you need. Our same-day delivery planning guide has tips.

Edibles: the limit isn't a serving size

A 1,000 mg daily limit is a legal ceiling on sales, not a suggested amount. Edibles are sold in small, labeled servings, and the dose that suits one adult can be too much for another.

Start low, go slow. State-required labels carry this warning: the impairment effects of edibles may be delayed by two hours or more. Wait at least that long before deciding whether to have more. Read our first-timer's edibles guide before your first order, and check each product's label and lab results for the THC per serving.

Where you can use what you buy

Staying under the limits doesn't make every place legal. According to the CCC:

• You can't consume cannabis in public places or on federal land, by any method.
• It's illegal to drive under the influence. Keep cannabis in a closed container in a vehicle.
• You can't take cannabis across state lines, even into another legal state, or send it by mail.

Medical patients

Registered medical patients and caregivers have separate limits. According to the CCC's Bulletin No. 1, they can continue to buy up to 10 ounces of flower or 1.9 ounces of concentrate. This site serves adult-use customers only.

Quick reference

• Buy per day: 2 oz flower, or 10 g THC concentrate, or 1,000 mg THC edibles (combined)
• Carry: 2 oz or the equivalent
• Keep at home: 10 oz plus home harvest
• Grow: 6 plants per adult, 12 per residence
• Deliver: 1 order of up to 2 oz, once per day

Limits are from M.G.L. c. 94G, § 7 and CCC orders as of September 2026. This isn't legal advice, and the CCC is still finalizing its regulations under Chapter 65. For adults 21+ only.
