SALEM, Ore. (AP) — In what would be a first in the U.S., possession of small amounts of heroin, cocaine, LSD and other hard drugs could be decriminalized in Oregon under a ballot measure that voters are deciding on in Tuesday’s election.

Oregon’s Measure 110 is one of the most watched referendums in the state because it would drastically change how the justice system treats people with amounts of the drugs for their personal use.

Instead of going to trial and facing possible jail time, people caught with the drugs would have the option of paying $100 fines or attending new “addiction recovery centers.”
