Medical Marijuana in Portland: OMMP Cards, Tax-Free Purchases and Medical Dispensaries

Oregon Medical Marijuana Program (OMMP) cardholders pay no state or Portland cannabis tax at medically registered dispensaries, can buy up to 8 ounces of flower a day and 32 ounces a month, and can shop from age 18. In Portland, 167 of the 186 licensed dispensaries are registered to serve OMMP patients. Some, such as Arcanna at TJ’s (40% off for medical patients) and Uplift Botanicals (bulk OMMP deals), add patient discounts on top.

Oregon’s medical program is run by the Oregon Health Authority (OHA), which issues OMMP cards; the OLCC registers retailers to sell to patients. Recreational shoppers pay Oregon’s 17% state cannabis tax and, inside Portland, the 3% city tax — so for regular buyers, the 20% savings can be significant.

What an OMMP Card Gets You in Portland

• No cannabis tax: retailers may not charge tax on purchases for an OMMP patient or caregiver (OAR 845-025-2800). Portland’s 3% city tax exempts cardholders too.
• Higher limits: up to 8 ounces of usable flower per patient per day, and up to 32 ounces per calendar month, versus 2 ounces a day for recreational buyers.
• Access from 18: patients and caregivers aged 18 to 20 with a valid OMMP card can buy at medically registered stores.
• No mark-up: stores may not charge cardholders a higher pre-tax, pre-discount price than other customers.
• Delivery outside city limits: medical patients can receive deliveries outside the store’s city, which recreational customers cannot.

How to Get an OMMP Card

You apply through the Oregon Health Authority with a signed attending provider statement from an Oregon-licensed physician or other qualifying provider confirming a qualifying condition. Fees, qualifying conditions and reduced-fee options are listed on the OHA’s OMMP pages. Oregon’s program is for Oregon residents; bring your OMMP card, not an out-of-state medical card, to get tax-free pricing.
