In Massachusetts, a medical patient and an adult-use shopper follow different rules. The Commission lists a different minimum age, different documents, different tax and different quantity limits. This page puts them in one table, from the Commission pages and 935 CMR 501, and does not rank one against the other.

What a medical purchase needs first
To buy as a medical patient you need an active certification from a certifying provider and an active registration with the Commission. At the door of a Medical Marijuana Treatment Center, 935 CMR 501.140(2) has the center check your temporary or annual Registration Card and a government-issued photo ID that shows your name and date of birth. A center must refuse to sell to a patient or caregiver without both.
What stays the same
- Both are for use in private. The Commission says you cannot use cannabis in any form in public places or on federal land.
- Neither may cross state lines. The Commission says it is illegal to drive across state lines with cannabis or to take it on a plane, train or boat out of Massachusetts, and you cannot mail it.
- Employers, landlords, cities and towns may set their own policies for both.
Where Advanced Dispensary fits
Advanced Dispensary in Peabody is a medical dispensary. That means a registered patient or caregiver shops there, not an adult-use shopper. It has no opening date yet. If you want to be ready, the card steps are on the patient hub.
Advanced Dispensary is a medical dispensary being renovated at 25 Newbury Street, on Route 1 in Peabody. It will serve registered patients and caregivers. It has no opening date yet. Phone: (978) 896-6640.
The tax numbers
The tax lines come from the Commission. You can try the numbers on the tax savings page. The calculator there is an estimate and not an AC price.
