At a licensed Oregon dispensary, an adult 21 or older can buy up to two ounces of usable marijuana flower per day. That is the headline number most people are asking about, but how much weed you can buy in Oregon also depends on the product: edibles, drinks, concentrates, vape cartridges, seeds, and starter plants each have their own separate daily cap. Registered medical patients can buy much larger quantities.
Recreational Purchase Limits by Product
An OLCC-licensed retailer cannot sell a recreational customer more than the following amounts in a single transaction or within one day:1Oregon Liquor and Cannabis Commission. OLCC Recreational Marijuana Retail Sale Limits
- Usable marijuana (flower): 2 ounces
- Solid cannabinoid products (edibles): 16 ounces
- Liquid cannabinoid products (drinks, tinctures): 72 fluid ounces
- Cannabinoid extracts or concentrates: 10 grams
- Cannabinoid products for inhalation (vape cartridges and similar): 10 grams
- Marijuana seeds: 10
- Immature plants: 4
The inhalable category catches people off guard because it sounds like it should fall under the concentrate cap. It doesn’t. Vape cartridges have their own 10-gram allowance on top of the 10 grams of extracts or concentrates, so you can walk out with both in the same visit.
These caps apply the same way whether you buy in person or receive a home delivery from an OLCC-licensed retailer.2Oregon Liquor and Cannabis Commission. Frequently Asked Questions You cannot split a purchase across two dispensaries in the same day and legally exceed the totals; the limits are per person per day, not per store.
Medical Marijuana Purchase Limits
Registered patients in the Oregon Medical Marijuana Program, or their designated primary caregivers, can buy considerably more in a single day:3Oregon Health Authority. Medical Marijuana Program FAQs
- Usable marijuana: 24 ounces
- Solid cannabinoid products: 16 ounces
- Liquid cannabinoid products: 72 ounces
- Cannabinoid concentrate: 16 ounces
- Cannabinoid extract: 5 grams
- Immature plants: 4
- Seeds: 50
The largest gap is on flower. A medical patient can buy twelve times what a recreational customer can in the same trip. The concentrate cap is also on a different scale entirely, jumping from 10 grams to 16 ounces. Medical patients can buy from OLCC-licensed retailers, from medical dispensaries regulated by the Oregon Health Authority, or directly from their designated grower.
What You Can Buy vs. What You Can Legally Hold
The daily buy limit is not the same as your possession limit, and the two rules can pull in different directions.
Away from home, a recreational adult can carry no more than two ounces of usable marijuana in any public place, along with 16 ounces of solid products, 72 fluid ounces of liquid products, one ounce of cannabinoid extracts, and 10 grams of concentrates.4Oregon State Legislature. Oregon Revised Statutes Chapter 475C Cannabis Regulation
At home, the ceiling on usable marijuana rises to eight ounces. That eight-ounce figure applies to the household as a whole, not to each adult who lives there. Four roommates sharing a house share one eight-ounce cap. Any flower produced from home-grown plants counts toward that same total.
Registered medical patients and their caregivers can jointly possess up to 24 ounces of usable marijuana.
Where and How to Buy
Every legal cannabis purchase in Oregon runs through a state-licensed retailer. Recreational shoppers use dispensaries licensed by the Oregon Liquor and Cannabis Commission. Medical patients have the additional option of buying from OHA-licensed medical dispensaries or receiving cannabis directly from a designated grower.
Retailers that register for delivery can bring cannabis to your address between 8:00 a.m. and 9:00 p.m., with a limit of one delivery per address per day. The same purchase caps apply. Recreational delivery is restricted to the retailer’s own jurisdiction and to adjacent jurisdictions that have opted in by local ordinance, so a store in one city may or may not be allowed to deliver to yours. Medical patients can receive deliveries anywhere in the state.5Oregon Liquor and Cannabis Commission. Cannabis Adjacent Jurisdiction Opt-In Home Delivery
Bring cash. Because cannabis is still federally illegal, Visa and Mastercard don’t process dispensary sales. Most shops run on cash or debit, often with an on-site ATM, and some use point-of-banking systems that act like an ATM withdrawal at the counter.
Taxes at the Register
Oregon adds a 17% state tax to recreational cannabis sold at OLCC-licensed retailers. Cities and counties can layer on up to 3% more if local voters approve, taking the combined rate as high as 20%. Not every jurisdiction has adopted the local piece, so the price you pay depends on where the store sits.6Oregon Liquor and Cannabis Commission. Marijuana Tax Distributions Medical purchases through the OMMP are handled separately and may be taxed differently.
Penalties for Going Over the Limit
If you exceed Oregon’s caps, the consequences scale with how far past the limit you go. For usable marijuana in public, where the base limit is two ounces:7Oregon State Legislature. Oregon Code 475C.337 Unlawful Possession of Marijuana Item
- More than 2 oz but no more than 4 oz: Class B violation, presumptive fine of $2658Oregon Public Law. ORS 153.019 Presumptive Fines Generally
- More than 4 oz but no more than 8 oz: Class B misdemeanor, up to 6 months in jail
- More than 8 oz: Class A misdemeanor, up to 364 days in jail
- More than 8 pounds: Class C felony, up to 5 years in prison
For usable marijuana anywhere, including at home, the base limit is eight ounces:
- More than 8 oz but no more than 1 pound: Class B violation
- More than 1 pound but no more than 2 pounds: Class B misdemeanor, up to 6 months in jail
- More than 2 pounds: Class A misdemeanor, up to 364 days in jail
- More than 8 pounds: Class C felony, up to 5 years in prison
The same multiplier structure applies to solid products, liquids, concentrates, and extracts, each measured against its own base limit.
One sharper edge in the statute is worth knowing before you buy: possessing any cannabinoid extract that did not come from a licensed OLCC retailer becomes a Class C felony once the amount tops one-quarter ounce, regardless of whether you are otherwise within the quantity caps. That provision is aimed at homemade and unregulated concentrates.
Anyone under 21 who possesses cannabis faces a Class A misdemeanor by default. The charge escalates to a Class C felony above 16 times the adult base limit and to a Class B felony (up to 10 years in prison) above 32 times the limit.9Oregon Public Law. ORS 475C.341 Unlawful Possession by Person Under 21 Years of Age
One last thing to keep in mind about your purchase: Oregon’s rules stop at the state line. Carrying any of what you bought across a state border, or onto federal land such as a national forest or national park, is a federal offense even if the destination is another legal state.10Office of the Law Revision Counsel. 21 USC 844 Penalties for Simple Possession
