Cannabis in Oregon is legal for both medical and recreational use. In recent decades, the U.S. state of Oregon has had a number of legislative, legal and cultural events surrounding the use of cannabis.

An attempt to recriminalize the possession of small amounts of cannabis was turned down by Oregon voters in 1997.
In the United States, the use of cannabis for medical purposes is legal in 39 states, four out of five permanently inhabited U.S. territories, and the District of Columbia, as of March 2023. Ten other states have more restrictive laws limiting THC content, for the purpose of allowing access to products that are rich in cannabidiol (CBD), a non-psychoactive component of cannabis. There is significant variation in medical cannabis laws from state to state, including how it is produced and distributed, how it can be consumed, and what medical conditions it can be used for.

Those signatures were needed for the required ten qualified voters who submitted the original petition to put forward the full text of the law they want enacted. The initiative passed with support from 63% of state voters.

The bill required a super-majority vote to pass, with at least 60% of voters voting for support of a state constitutional amendment. Florida already had a medical marijuana law in place, but only for those who are terminally ill and with less than a year left to live.
