May I come to your dispensary with a Massachusetts or out of state medical marijuana card?

Yes!  By the Department of Health Standards, Rhode Island can now accept out of state medical marijuana patients. Rhode Island currently has full reciprocity with each state within the United States. Please bring an up-to-date form of identification. This includes a Passport, State license, or State Issued Identifiction Card as well as your medical marijuana card. Expired forms of identification cannot be accepted, even if Medical Marijuana Patient card/document is valid and up-to-date. If you qualify as a Veteran, please bring the appropriate documentation to qualify for a 10% Out of State Veteran discount.

What is your policy regarding medical marijuana patients under the age of eighteen?

Rhode Island

A Rhode Island MMJ patient under the age of eighteen may come into the facility if and only if they are accompanied by their legal guardian who has obtained his or her official Rhode Island MMJ Caregiver or MMJ Authorized Purchaser cards. A patient under the age of eighteen cannot approach, stand, or make a purchase at the medicinal stations independently. The patient’s RI MMJ Caregiver or RI MMJ Authorized Purchaser is permitted to purchase and handle the medicine thereon after on behalf of the patient.

Out of State

Per Rhode Island Department of Health and current state regulations, Greenleaf is unable to accept authorized MMJ Caregivers for Out of State patients, thus making us unable to provide medicine to the respective underage patient.  


What form of payment do you accept?

Greenleaf accepts Cash and Check. There is an ATM inside the facility for your convenience.

May I bring a guest with me?

Only patients with valid medical marijuana cards are permitted inside the building. Any questions or concerns you have regarding which medicine to purchase can be discussed with our bud tenders. Patients needing assistance due to mobility or communication issues are allowed to have a caretaker accompany them after signing in with Security.

How many grams may I purchase?
2.5 Ounces (70 grams) every rolling 15 days

How can I figure out how many grams I have left on my account?

It is ultimately up to each respective patient to keep track of his or her legal limit remaining on his or her account. The bottom of each sales receipt displays the patient’s “Remaining Limit” for the day. Patients are permitted 70 grams within a timespan of a 15-day rolling window.

It is against the Department of Business Regulations for Greenleaf to give a patient’s remaining limit, purchase history, or any patient information over the phone. We can, however, assist a patient in figuring out the remaining limits once he/she or the caregiver has presented the appropriate medical marijuana card in person.

Example: If John Smith comes in and purchases 5 grams, those 5 grams will be back on John’s account in 15 days. If John comes back the next day and purchases 7 grams, those 7 grams will be back on his account 15 days from then. This way, when a patient makes numerous visits, those grams will return on a “rolling” basis.

Rhode Island Patients: You may look up your available limit through our website in our ‘Services’ tab or through our mobile app. Each option will require the digits on your medical marijuana card.

Out of State Patients: Unfortunately, there is no “Limit Look-Up” for Out of State Patients at the moment. Each patient must keep track of his or her ‘usable grams’ utilized or come in person for assistance. We recommend each patient look at the bottom of his or her receipt which displays his or her remaining limit. This will be the easiest method to track one’s own limit. 

Do your CBD products have THC in them?

Yes. All our medicinal products are strictly cannabis derived and therefore will have trace amounts of THC (5% or less). Medicinal products containing more than 5% THC are labeled accordingly as these products may affect patients differently than our usual CBD products.  We also carry varying ratios, such as 1:1 containing an even amount of THC and CBD. As ratios and doses vary, please read labels on edibles carefully.

Out of State Patients must have both their Medical Marijuana Card/Document and valid form of identification each visit to make a purchase.
