What’s different in Massachusetts
A new state law changed several rules in 2026. Chapter 65 of the Acts of 2026, signed April 19, 2026, raised the limit you can carry from 1 ounce to 2 ounces and allowed adult-use delivery across the state. The Cannabis Control Commission (CCC) has one year to update its rules to match, so some details may still change.
Cities and towns can limit or ban licensed cannabis businesses. In a town where most voters backed Question 4 in 2016, a ban has to go to local voters. CCC's Municipal Zoning Tracker shows the status of all 351 cities and towns. A town with no licensed stores can ask CCC for a waiver to block delivery for up to 2 years at a time. CCC had issued 13 of these waivers as of July 15, 2026.
You can't use cannabis in a public place, or smoke it where tobacco smoking is banned. The fine is up to $100. An open container of cannabis in the passenger area of a car can bring a fine of up to $500. CCC says you can't take cannabis across state lines or mail it, even to a place where it is legal.
Hemp products follow different rules. The Massachusetts Department of Agricultural Resources (MDAR), not CCC, regulates hemp. MDAR says it does not allow hemp-derived delta-8 THC products to be made or sold in Massachusetts. The 2026 law told CCC to study hemp-derived cannabinoid products and report by December 15, 2026.
Licensed does not mean risk-free. Products must be tested before sale, and CCC posts public health and safety advisories about contaminated or possibly contaminated products.
Massachusetts rules at a glance
These are the main state rules for adult-use cannabis. Cities and towns can add their own rules. Numbers in brackets link to the law or the regulator’s guidance.
| Topic | The rule | Source |
|---|---|---|
| Minimum age | 21 and older for adult use. Stores must refuse a sale if you can't show a valid government-issued ID. People under 21 can buy only as registered patients in the state's medical marijuana program. | Source [1] CCC Know the Laws; G.L. c. 94G, § 13(f); 935 CMR 500.140(4)(a) |
| How much you can have | Adults 21 and older may carry up to 2 ounces of marijuana, or the same amount in other products as set by CCC. CCC says no more than 10 grams of that may be concentrate. At home you may keep up to 10 ounces, plus what your home plants produce. Anything over 2 ounces at home must be locked up. Stores and delivery can sell you up to 2 ounces (or the same amount in other products) per day. | Source [2] G.L. c. 94G, § 7(a)(1)–(2), as amended by St. 2026, c. 65, § 29 (effective April 19, 2026); § 13(b); CCC FAQ; 935 CMR 500.140(3) |
| Growing at home | Up to 6 plants per adult 21 or older in their primary home, and no more than 12 plants in one home. Plants must be in an area with a lock and must not be visible from a public place without binoculars, aircraft or other optical aids. Landlords can restrict home grow. | Source [2] G.L. c. 94G, § 7(a)(2); § 13(a); CCC Home Cultivation page |
| Delivery | Allowed from CCC-licensed delivery businesses. Since April 19, 2026, adult-use delivery is allowed across the state, except in towns with no licensed stores that get a CCC waiver (up to 2 years at a time). Delivery goes only to a house, condo or apartment, not to dorms, hotels or federal public housing. Your ID is checked before your first order and again at the door. An order can't be more than 2 ounces or the same amount in other products. | Source [3] St. 2026, c. 65, § 25 (G.L. c. 94G, § 4(b)(2)); 935 CMR 500.002 (Residence), 500.145(1)–(4) |
| Required lab tests | Before sale, every product must be tested by an independent testing laboratory licensed by CCC and meet CCC's testing protocols. Tests cover THC and other cannabinoids, and contaminants including mold, mildew, heavy metals, plant growth regulators and pesticides. Vape products are also screened for heavy metals and vitamin E acetate. Test results are good for one year; older products can't be sold until retested. | Source [4] 935 CMR 500.160(1), (2), (5); G.L. c. 94G, § 15(a) |
| Labels | Labels must list the business that made the product, a batch number, the net weight, and the THC and other cannabinoid amounts. They must state that the product was tested for contaminants with no adverse findings, and give the test date. They also need CCC's symbol for marijuana, a symbol that the product is harmful to children, and a warning that ends "KEEP THIS PRODUCT AWAY FROM CHILDREN." Edible labels also show the THC per serving and in total, a use-by date, and a warning that effects may be delayed by two hours or more. | Source [4] 935 CMR 500.105(5)(a)–(b); 500.150(3) |
| Packaging | Cannabis sold to consumers must be in child-resistant packaging. Where practical, packages must be opaque and plain, and resealable if they hold more than one use or serving. If child-resistant packaging isn't practical, the product goes in a resealable child-resistant exit package marked "KEEP OUT OF REACH OF CHILDREN." Packaging can't use neon colors, cartoons or images that appeal to minors. Multi-serving packages must say "INCLUDES MULTIPLE SERVINGS." | Source [4] 935 CMR 500.105(6)(a)–(c) |
| Edible THC limits | A serving can have no more than 5 mg of THC. With the allowed 10% testing variance, the limits are 5.5 mg per serving and 20 servings or 110 mg of THC per package. Solid edibles must be scored into servings or sold as single servings, and each serving is marked with CCC's symbol. Drinks are sold only as single servings. Edibles can't be shaped like people, animals, fruit or sports equipment. | Source [4] 935 CMR 500.105(6)(c)–(e); 500.150(1)(b), (4) |
