1Whose life is it?
A question of principle: personal freedom against protecting life.
Supporters say dying people deserve a peaceful choice. Opponents fear pressure on the vulnerable and rules that keep widening.

Euthanasia means a doctor deliberately ending the life of a patient who asks to die, usually with an injection. In medical aid in dying, also called assisted dying, a doctor prescribes lethal medication that the patient takes themselves. Both are meant for adults who are seriously ill and suffering, and the debate is about whether the law should allow them.
Oregon became the first US state to allow aid in dying when its law was passed in 1997.1 That same year, the US Supreme Court ruled 9 to 0 that there is no constitutional right to assisted suicide, but left the question to the states: “Our holding permits this debate to continue, as it should in a democratic society.”11
Many states have since followed. Illinois became the 12th state to allow it in December 2025 and New York the 13th in February 2026, alongside Washington, DC.65 In Oregon in 2025, 400 people died after taking the medication, about 1.0% of all deaths in the state. Their median age was 76, and 61% had cancer.1 Most Americans approve: in 2024, 71% told Gallup that doctors should be allowed by law to end a terminally ill patient's life if the patient and family ask.3
Some countries go further. Canada's Supreme Court struck down its ban in 2015, and in 2024, 16,499 people in Canada received medical assistance in dying, 5.1% of all deaths in the country.122 In the Netherlands, 9,958 people died by euthanasia in 2024, 5.9% of all deaths, including 219 people whose suffering came from psychiatric conditions.4
Personal stories drive the argument on both sides. In 2014 Brittany Maynard, a 29-year-old with terminal brain cancer, moved from California to Oregon to use its law. On the day she died she wrote, “Today is the day I have chosen to pass away with dignity in the face of my terminal illness.”9 California passed its own law the next year.10 Critics point instead to Alan Nichols, a 61-year-old Canadian whose 2019 request to die listed only one health condition: hearing loss. His brother said, “Alan was basically put to death.”19
The fault lines run deep. The American Medical Association says physician-assisted suicide “is fundamentally incompatible with the physician’s role as healer.”14 Disability groups fear that people will choose death because they feel like a burden, a concern listed by 39.8% of Oregon patients in 2025. Supporters reply that the top reasons were losing autonomy and losing the activities that made life enjoyable, each cited by 89%.1
Elsewhere the votes are close. British MPs backed a bill for England and Wales by 314 to 291 in June 2025, but it ran out of time in the House of Lords in April 2026, after opponents filed more than 1,200 amendments. A month earlier, the Scottish Parliament had rejected a similar bill.87
Most debates on assisted dying are won or lost on these four questions.
A question of principle: personal freedom against protecting life.
Both sides point to the same countries and read them differently.
Medical groups themselves are divided.
Nobody disputes that end-of-life care could be better. They disagree on what follows.
The US: 13 states and Washington, DC allow medical aid in dying for terminally ill adults, most recently Illinois, Delaware and New York.65
Canada and the Netherlands: both allow euthanasia by a doctor, and it now accounts for about 5% to 6% of all deaths in each country.24
Europe: Spain became the fourth EU country to legalise euthanasia in 2021, after Belgium, Luxembourg and the Netherlands.28 People travel to Switzerland to die at clinics such as Dignitas.27
Elsewhere: New Zealand voters approved a law in a 2020 referendum by 65.1%.26 Australia and Portugal also allow it, while in 2026 both the UK Parliament and the Scottish Parliament failed to pass bills.7
Debate tip: foreign examples are evidence for both sides. Pro can point to Oregon's long, closely watched record; Con can point to how quickly Canada's rules and numbers grew.
