How Assisted Dying Laws Differ Worldwide: Key Changes, Rules and Debates

Around 400 million people now live in countries that have legalised some form of assisted dying. Laws and safeguards vary widely: some jurisdictions limit access to terminally ill adults, while others allow assistance for people experiencing unbearable suffering from an irreversible condition.

North America

United States: Assisted dying (often called assisted suicide by critics) is legal in 13 states plus Washington, D.C. Oregon’s 1997 law — restricted to mentally competent adults with a prognosis of six months or less — has been highly influential. Since its introduction, 5,520 people in Oregon have received prescriptions for a lethal dose and 3,691 deaths have been recorded.

A 2025 Oregon report found the main diagnoses of patients requesting help were: cancer (61%), neurological disease such as motor neurone disease (14%), and heart disease (11%). The top reasons cited by those who used lethal medication were loss of autonomy (89%), loss of dignity (65%), loss of control of bodily functions (47%), concern about burdening family and friends (43%), inadequate pain control (28%), and financial concerns (4%). In most US states, including Oregon, the medication must be self-administered.

Canada: Medical Assistance In Dying (MAID) began in 2016 for terminal patients and was expanded in 2021 to include people suffering "unbearable" harm from irreversible illness or disability. Plans to extend MAID to people whose only condition is mental illness have been paused. MAID’s growth — now accounting for roughly 1 in 20 deaths in Canada compared with ~1 in 100 in Oregon — fuels debate about safeguards and risks to disabled and vulnerable people.

Europe

Several European countries permit assisted dying in varying forms: Switzerland, the Netherlands, Belgium, Luxembourg, Spain, Austria, Portugal (approved in 2023 but not yet in force), and most recently France (2025), which allows aid in dying for adults with incurable conditions causing unbearable suffering. Eligibility ranges from strictly end-of-life criteria to broader standards of intolerable or unbearable suffering.

The Netherlands and Belgium, pioneers for more than two decades, allow euthanasia (physician-administered lethal drugs) and have extended eligibility in limited ways, including provisions for children. Italy and Germany have seen constitutional or court rulings removing criminal penalties for assisted suicide in specific circumstances, and in 2025 Tuscany created a regional legal process for medically assisted suicide.

British Isles

At UK national level (England, Wales and Scotland), assisted dying proposals have been rejected. However, Crown Dependencies have moved differently: Jersey received Royal Assent in July for assisted dying legislation that includes a one-year residency requirement and allows physician-administered intravenous lethal doses (voluntary euthanasia). The Isle of Man passed an assisted dying bill in Tynwald but awaits Royal Assent from the UK government; that bill includes a five-year residency requirement.

Oceania

Most Australian states and territories have legalised voluntary assisted dying; the Northern Territory became the final Australian jurisdiction to pass such legislation recently. In Australia and New Zealand patients are generally expected to be terminally ill (commonly six months' prognosis, extended to 12 months for some neurodegenerative conditions in parts of Australia). Both self-administration and practitioner administration (usually intravenous) are permitted in jurisdictions that allow euthanasia.

Latin America

Uruguay passed a law in 2025 permitting assisted dying for adults with incurable or terminal illness. Elsewhere in the region, Colombia, Ecuador and Cuba have decriminalised euthanasia.

Key Issues And Debates

• Eligibility: Terminal illness vs. unbearable suffering or irreversible conditions.
• Method: Self-administration versus physician administration (euthanasia).
• Residency And Access: Rules intended to prevent "death tourism" vary from one-year to five-year residency requirements in some jurisdictions.
• Safeguards And Concerns: Critics warn of a "slippery slope" and potential risks to disabled and vulnerable people as eligibility expands.

Supporters say carefully designed systems respect autonomy and relieve suffering; opponents warn that expanding access can increase risks and dilute safeguards.

While an increasing number of jurisdictions have permitted assisted dying in some form, practices and protections differ substantially. Readers should note that some laws approved by legislatures are subject to court challenges, implementation delays or regulatory processes before services become operational.
