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

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.

Short answers

Do medical patients pay the state cannabis tax?

The Commission says there is no state excise tax and no standard sales tax on medical marijuana sales, and medical sales are exempt from the local tax option.

How old do I have to be for each?

A patient can be 18 or older and a caregiver has to be 21 or older. Adult-use buyers must be 21 or older.

Can I buy a medical amount without a card?

No. The Commission says you need both an active certification and an active registration to buy medical marijuana.

Is Advanced Dispensary an adult-use shop?

No. It is a medical dispensary and will serve registered patients and caregivers.
