Thirty-two politicians voted in favour of the law with 16 voting against it.
Jersey Minister for Health and Social Services, Tom Binet, said: “Jersey would have one of the safest and most transparent assisted dying laws in the world.”
Lorna Pirozzolo, from Jersey, who has terminal breast cancer, said the reform to law was “badly needed”.
“Like so many terminally ill people I’ve spoken with, I’m not scared of dying, but I am terrified of suffering as I go. That’s why this law is so badly needed.
“Today brings enormous relief, not just for me, but for future generations of islanders who deserve compassion, choice and dignity at the end of life.”
Humanists UK chief executive Andrew Copson said it was a “momentous vote of confidence for compassion, dignity, and choice at the end of life”.
“For far too long, terminally ill people were denied the right to decide the manner and timing of their own deaths. Today, Jersey has changed that,” he said.
“The proposals contain strong safeguards and reflect the clear wishes of the public, who have spoken through citizens’ juries and repeated surveys.”
