Marijuana laws in Oregon
Oregon voters legalized adult-use marijuana by passing Measure 91 on November 4, 2014. The law took effect July 1, 2015. Medical marijuana has been legal since Measure 67 in 1998. The current statutes are in ORS chapter 475C, overseen by the Oregon Liquor and Cannabis Commission and the Oregon Health Authority.
Adults 21 and older may possess up to two ounces of usable marijuana in a public place and up to eight ounces at a household. A household may also have up to four homegrown plants, 16 ounces of solid cannabinoid products, 72 ounces of liquid cannabinoid products, 16 ounces of concentrates, and cannabinoid extracts bought from a licensed retailer or medical dispensary. Exceeding those amounts is unlawful possession, from a Class B violation up to a felony depending on the amount.
Licensed retailers sell to adults 21 and older with valid ID. Medical patients can also use the Oregon Medical Marijuana Program. Using a marijuana item in a public place is prohibited. Driving under the influence of intoxicants is illegal.
Marijuana remains illegal under federal law, apart from state-licensed medical marijuana, which moved to Schedule III in April 2026.

How old do you have to be to use marijuana in Oregon?
You have to be 21 to buy weed in Oregon. Licensed retailers may sell only to adults 21 and older who show valid ID. People under 21 may not possess, buy or attempt to buy marijuana items, with medical-program exceptions for registered patients. Homegrown plants and household possession limits in ORS 475C.305 also apply to persons 21 years of age or older.
How much marijuana can you have in Oregon?
Adults 21 and older in Oregon can have up to two ounces of usable marijuana in a public place and up to eight ounces at home. A household may also keep up to four plants, 16 ounces of solid cannabinoid products or concentrates, 72 ounces of liquid cannabinoid products, and extracts bought from a licensed retailer or medical dispensary. In a car, treat the public-place two-ounce cap as the limit you can have on you. More than those amounts is unlawful possession.
Where can you buy marijuana in Oregon?
You can buy weed in Oregon at retailers licensed by the Oregon Liquor and Cannabis Commission. Adults 21 and older need a valid ID. Medical patients can also obtain marijuana through the Oregon Medical Marijuana Program, including registered medical dispensaries. Buying from an unlicensed seller is not legal. Cannabinoid extracts generally must be purchased from a licensed retailer or transferred by a registered medical dispensary.
Can you grow marijuana at home in Oregon?
Yes. Adults 21 and older in Oregon can grow up to four homegrown plants at a household, no matter how many adults live there. The plants are for noncommercial use. A household may also keep up to eight ounces of usable marijuana from that grow, plus homemade products within the solid- and liquid-product caps. Making cannabinoid extracts at home is not allowed; extracts have to come from a licensed retailer or a registered medical dispensary.
Where can you use marijuana in Oregon?
You can smoke weed in Oregon mainly on private property. State law prohibits using a marijuana item in a public place. Licensed premises and some local rules can set additional limits. Landlords may restrict smoking in leases. Using marijuana while driving, or driving under the influence of intoxicants, is illegal.
How do you get a medical marijuana card in Oregon?
To get a medical marijuana card in Oregon, you apply to the Oregon Medical Marijuana Program through the Oregon Health Authority. You need a qualifying condition and a physician's or authorized provider's recommendation. A card can allow medical purchases and other program privileges separate from the adult-use system. Adults 21 and older can also buy at licensed retail stores without a medical card.
Can visitors buy or use marijuana in Oregon?
Yes. Out-of-state visitors can buy marijuana in Oregon if they are 21 or older. Licensed adult-use retailers accept a valid government ID showing the buyer is 21 or older, and there is no residency requirement for those purchases. Visitors follow the same possession, public-use and home-grow rules. Taking cannabis out of Oregon across state lines is not protected by state law and remains illegal under federal law.
What are the rules on driving and marijuana in Oregon?
No, you can't drive high in Oregon. Driving under the influence of intoxicants, including marijuana, is illegal. Oregon does not give drivers a THC-level safe harbor just because the marijuana was bought legally. Using a marijuana item while driving is also prohibited.
Can an employer in Oregon fire you for using marijuana?
Yes, you can get fired for smoking weed in Oregon. Adult-use legalization does not require employers to allow marijuana use, possession or impairment at work, and it does not generally bar drug testing. Employers may keep drug-free workplace policies, including for safety-sensitive jobs and federally required testing.
What are the penalties for breaking marijuana laws in Oregon?
If you are 21 or older, going over Oregon's possession caps is unlawful possession. Up to twice the limit is a Class B violation. More than twice but not more than four times the limit is a Class B misdemeanor. Default unlawful possession is a Class A misdemeanor, and larger amounts can be Class C or Class B felonies, including more than eight pounds of usable marijuana in a public place. Unlicensed sales and manufacturing are separate crimes.
Are CBD, hemp and delta-8 products legal in Oregon?
Hemp is regulated separately in Oregon from licensed marijuana. Intoxicating hemp products, including some delta-8 and THCA items, may be treated as marijuana items if they do not meet the hemp definition or OLCC rules. Extracts generally have to come from a licensed marijuana retailer. Separately, a stricter federal hemp definition, with a total-THC standard that counts THCA and a 0.4 mg-per-container cap, takes effect December 11, 2026.
Does federal law still apply in Oregon?
Yes. Federal law still applies in Oregon. Marijuana remains a Schedule I controlled substance under federal law, with one exception: since April 28, 2026, marijuana covered by a state medical marijuana license and FDA-approved marijuana products are in Schedule III. A broader federal rescheduling proceeding was stayed on September 29, 2026, and has no decision date. State law does not change federal rules on federal land, on carrying marijuana across state lines, or on federally required drug testing, such as for DOT-regulated jobs.
Has the law in Oregon changed recently, or is it about to?
Oregon's adult-use and medical programs are in place and were not replaced in 2026. Possession and home-grow limits remain those in ORS 475C.305 and 475C.337: four plants per household, two ounces in public and eight ounces at home. New federal hemp limits begin November 12 and December 11, 2026.
