Proposition 106 has passed in Colorado, making the state the nation's sixth to legalize assisted suicide, reports 9NEWS. Adults who are terminally ill, with less than six months to live, and found to be mentally competent, can request life-ending medication—a high dose of secobarbital used in sleeping pills—from a doctor, reports the Denver Post; those with dementia or Alzheimer's aren't eligible. The measure passed with two-thirds support with 63% of votes counted, per the Post. Advocates called it a "tremendous victory," while "disappointed" critics promised that "the fight is not over."
