Understanding Massachusetts Cannabis Law

Massachusetts made history in 2016, becoming the first state on the East Coast to legalize recreational cannabis. Since then, cannabis culture in the state has exploded, becoming a trailblazer for all East Coast states who followed Massachusetts’ lead. Though the bill was initially passed several years ago, there have been updates to ensure the law keeps up with the rapidly changing cannabis landscape.


In this blog, we’ll go through everything you need to know about Massachusetts Cannabis Laws so you can stay informed and compliant while still enjoying the benefits of cannabis.

Licensing & Regulation

Massachusetts has established a comprehensive licensing system managed by the Cannabis Control Commission (CCC) which oversees medical and recreational cannabis operations.


The state issues licenses for a range of businesses, including cultivation, manufacturing, retail, and testing. Applicants undergo a rigorous process that includes background checks, business plans, and community agreements.

Medical Marijuana in Massachusetts

If you’re considering medical marijuana in Massachusetts, it’s essential to know the rules to stay on the right side of the law:

  • For those over 18 looking into medical marijuana, you’ll need approval from a physician and a certification from the state. This allows you to legally possess up to a 60-day supply of marijuana. Conditions that qualify for medical marijuana treatment in Massachusetts include ALS, Cancer, Crohn’s Disease, Parkinson’s Disease, and more.
  • The process is a bit more stringent for those under 18. Two certifying physicians in Massachusetts must approve pediatric patients, confirming that the patient has a debilitating or life-limiting illness or condition.
  • One of the perks for registered medical marijuana patients in Massachusetts is the ability to grow their own supply at home. You’re allowed up to twelve flowering and twelve vegetative plants for personal use.
  • To increase access to medical marijuana through home cultivation, there is a plan to develop the Hardship Cultivation Registration. The program is for individuals who need to grow enough marijuana for a 60-day supply due to financial hardship, physical incapacity, or living a significant distance from a Medical Marijuana Treatment Center (MTC). While not yet implemented, it is being worked on.
  • However, remember, using medical marijuana publicly is off-limits. This includes smoking, vaping, or eating any form of medical marijuana in public spaces or on federal property. Out-of-state residents, take note: you cannot purchase medical marijuana in Massachusetts. This privilege is reserved strictly for Massachusetts residents or their caregivers.
  • Also, be aware of your surroundings. Employers, landlords, and even whole cities or towns might have specific policies about marijuana use. And don’t think about crossing state lines with your medication; it’s illegal to transport medical marijuana out of Massachusetts, whether by car, plane, train, or boat, mail, or any other mode of transportation.

Recreational Cannabis in Massachusetts

If you’re diving into the world of recreational cannabis in Massachusetts, there are a few key points you’ll want to keep in mind to ensure your experience is both enjoyable and legal: 


  1. First off, you have to be at least 21 years old to buy or grow adult-use cannabis. When heading to a dispensary, don’t forget your government-issued ID, as you’ll need it to make any purchases.
  2. In Massachusetts, there’s a limit to how much cannabis you can have on you. The law lets you carry up to one ounce of cannabis and store up to 10 ounces in your home. If growing your own cannabis interests you, you can legally cultivate up to six cannabis plants for personal use, or up to 12 plants for households with two or more adults.
  3. For out-of-state visitors, you’re welcome to purchase cannabis in Massachusetts if you’re over 21 and have a valid government-issued ID. However, enjoy your purchases within state lines, as taking cannabis across state borders is illegal. And if you’re staying in a hotel or rental, make sure to check their policies on marijuana use before lighting up.
  4. Public consumption of cannabis, whether it’s smoking, vaping, or eating, is a no-go. This rule applies to public places and federal land alike. And while we’re on the subject of transportation, remember that open containers of any form of cannabis in the passenger area of a vehicle are illegal, similar to open alcohol containers. If you’re carrying cannabis in a car, keep it in a closed container, ideally stashed in the trunk or a locked glove compartment.
