Portland, OR Cannabis Regulations: Personal Cultivation Limits (2026)

Oregon's personal cannabis allowances are structured around the household (cultivation) and the person (possession). Cultivation: ORS 475C.301 permits 4 mature plants per household, with no per-person bonus -- a household of five adults is capped at the same 4 plants as a single adult. ORS 475C.305 confirms the exemption from licensing requirements for these homegrown plants. Possession: an adult 21+ may possess (a) 2 ounces of usable cannabis in a public place, (b) 8 ounces of usable cannabis at home, (c) 16 ounces of homemade cannabinoid edibles, (d) 72 ounces of homemade cannabinoid liquids, (e) 1 ounce of cannabinoid extract, and (f) 10 marijuana seeds. Combined household possession is the sum of what each adult resident may possess. No-cost gifting of up to 1 ounce of usable cannabis to another adult 21+ is permitted (ORS 475C.337); any sale or barter is unlawful. Federal preemption: federal law still classifies cannabis as a Schedule I controlled substance, so possession is illegal on federal property in Portland (Mt. Hood National Forest portions, federal courthouses, post offices, military bases, VA medical center). Penalties for exceeding limits scale up: 4-8 plants is a Class B misdemeanor; more than 8 plants is a Class B felony under ORS 475C.349. Possession above the public limits is a violation for small overages and a Class B misdemeanor for larger amounts under ORS 475C.341.
