Five States and The District of Columbia have created law concerning end of life decisions.   I think legislation has been proposed for Alaska; however,  our elected officials in Juneau fear an actual debate in an open forum and a subsequent recorded vote more than death itself.  Here is the list: 

California (End of Life Option Act; 2016)
Colorado (End of Life Options Act; 2016)
District of Columbia (Death with Dignity Act; 2017)
Oregon (Oregon Death with Dignity Act; 1994/1997)
Vermont (Patient Choice and Control at the End of Life Act; 2013) 
Washington (Death with Dignity Act; 2008)
