Portland FAQ

What is the maximum cannabis I can carry in public in Portland?

2 ounces of usable cannabis (flower) when in any public place, under ORS 475C.305. At home you may possess up to 8 ounces. Concentrated extract is limited to 1 ounce. Crossing onto federal property (post office, courthouse, military base) makes any possession a federal crime.

Can two adults in the same Portland household each grow 4 plants?

No. ORS 475C.301 caps cultivation at 4 mature plants per household, not per adult. Two, three, or five adults in the same dwelling share the same 4-plant maximum. Each adult does, however, have their own personal possession allowance.
