Legalization by states
Physician-assisted dying was first legalized by the 1994 Oregon Death with Dignity Act, with effect delayed by lawsuits until 1997.[15] The Montana Supreme Court ruled in Baxter v. Montana (2009) that it found no state law or public policy reason that would prohibit physician-assisted dying.[16]
It was legalized by Washington in 2008,[17] Vermont in 2013,[18] California[19][20] and Washington, D.C.,[21] and Colorado[22] in 2016, Hawaii in 2018,[23] New Jersey in 2019,[24] Maine in 2020,[25][26] and New Mexico in 2021[27] It had also been briefly legal in New Mexico in 2014 and 2015 due to a court decision that was overturned.
