Oregon recriminalises drug possession after overdoses rocket
The law rolls back an experimental policy - the most liberal drug measure in the US - that made possession for personal use a ticketed offence with a fine up to $100 (£76).
The new legislation penalises those possessing small amounts of drugs with probation, and up to 180 days in jail.
The governor said the state still aims to provide a path for drug treatment, rather than punishing drug users.
Tina Kotek, the Democratic governor, signed the bill on Monday. It goes into effect on 1 September.
Rehabilitation and destigmatisation was the intention of the original law, known as Measure 110, when it was passed in a 2020 voter measure, but a spike in the number of overdoses caused lawmakers and supporters to backtrack.
