Medically assisted suicide, more commonly called medical aid in dying, is the practice of a physician providing a terminally ill patient with lethal medication that the patient self-administers to end their life. The key distinction is that the patient, not the doctor, performs the final act. It is legal in a growing number of jurisdictions worldwide, though it remains ethically and legally contested.
How It Differs From Euthanasia
The terminology around assisted dying can be confusing, partly because different countries and organizations use different terms for overlapping practices. The core distinction comes down to who performs the final act. In medical aid in dying (also called physician-assisted suicide or physician-assisted dying), a doctor prescribes a lethal dose of medication, but the patient decides when and whether to take it. In voluntary active euthanasia, a physician or other person directly administers the drugs that cause death, at the patient’s request.
This difference matters legally. Many jurisdictions that allow patients to self-administer lethal medication still prohibit euthanasia. In the United States, for example, every state that permits aid in dying requires the patient to ingest the medication themselves. Canada is an exception: its medical assistance in dying (MAiD) program allows both self-administration and direct administration by a physician or nurse practitioner.
Where It Is Legal
In the United States, Oregon became the first state to legalize aid in dying through its Death with Dignity Act in 1997. Since then, roughly a dozen states and Washington, D.C. have followed with similar laws. Internationally, the Netherlands, Belgium, Luxembourg, Canada, Spain, Australia (in several states), New Zealand, and parts of other countries have legalized some form of assisted dying. Switzerland occupies an unusual position: its law does not require a physician to be involved at all. Swiss law treats assisting suicide as a crime only when the motive is selfish, which has allowed nonprofit organizations to provide assistance for altruistic reasons.
Canada’s MAiD program has expanded significantly since 2016 and now includes people whose natural death is not reasonably foreseeable. However, eligibility for people whose sole underlying condition is a mental illness has been repeatedly delayed and is currently postponed until March 17, 2027.
Who Is Eligible
Requirements vary by jurisdiction, but most U.S. states follow a similar framework. To qualify, a person must have an incurable condition that is expected to result in death within six months. They must be an adult, a resident of the state, and possess the mental capacity to make major medical decisions. The request must be voluntary, with no evidence of coercion.
If there is any question about a patient’s ability to make the decision, a mental health evaluation by a psychiatrist or psychologist is required. In Hawaii, this evaluation is mandatory for every person pursuing aid in dying, regardless of whether capacity concerns have been raised.
Legal Safeguards and the Process
U.S. laws build in multiple checkpoints. The process generally requires two physicians: a prescribing physician and a consulting physician who independently confirms the patient meets all legal criteria. The patient must see the prescribing physician at least twice, with a minimum 15-day waiting period between visits. New Mexico is the only state that does not require this waiting period. Throughout the process, the patient can withdraw their request at any time.
These safeguards are designed to ensure the decision is informed, voluntary, and consistent over time. The consulting physician’s role is specifically to verify the diagnosis, prognosis, and the patient’s capacity to make the decision.
What the Process Looks Like for Patients
In the U.S. model, once a patient has completed all required visits and waiting periods, the prescribing physician writes a prescription for a lethal dose of medication. The patient fills the prescription at a pharmacy, takes it home, and decides independently whether and when to use it. Many people who receive prescriptions never take the medication. In Oregon in 2024, 607 people received prescriptions under the Death with Dignity Act, but only 333 of them (55%) died from ingesting the drugs.
In Canada’s intravenous model, the process is different. A healthcare provider first gives a sedative to reduce anxiety, followed by a local pain reliever, then an anesthetic that induces deep unconsciousness within seconds. After that, a medication that stops breathing is administered. The entire process, from sedation to death, typically takes only minutes. About a quarter of Canadian patients also receive an additional medication that stops the heart.
Why Patients Request It
The reasons are more complex than pain alone. In Oregon’s 2024 data, the three most frequently cited end-of-life concerns were loss of autonomy (91.4%), decreasing ability to participate in enjoyable activities (86.7%), and loss of dignity (71.4%). A Canadian study found a similar pattern: disease-related symptoms like pain and nausea were the top concern (59.8%), followed closely by loss of control and independence (52.7%), loss of ability to do meaningful activities (49.1%), and fear of future suffering (24.1%).
Cancer is by far the most common underlying illness. In Oregon’s 2024 data, 57% of patients had cancer, followed by neurological disease (15%) and heart or circulatory disease (11%).
Cost and Insurance Coverage
Coverage for aid-in-dying medications is inconsistent. Federally funded insurance plans in the U.S., including Medicare and Tricare, generally do not cover the medications because federal law does not recognize the practice. In one study of 35 patients prescribed the most common aid-in-dying drug at a single center between 2010 and 2016, only 12 (34%) received any insurance coverage, all through commercial plans. Their copayments ranged from $2 to over $1,200. The remaining 66% paid out of pocket or had federal insurance that would not cover it.
The Medical Profession’s Stance
The American Medical Association officially opposes the practice, stating that it is “fundamentally incompatible with the physician’s role as healer” and would pose serious societal risks. The AMA’s position is not one of neutrality. However, the AMA also acknowledges that individual physicians who, after careful moral consideration, choose to participate in legally authorized aid in dying will not be considered in violation of the AMA’s Code of Medical Ethics. This dual stance reflects the genuine division within the medical profession, where many individual doctors support the practice even as the largest professional organization does not.
Other medical organizations have taken different positions. Some have adopted formal neutrality, while others actively support aid-in-dying legislation. The debate within medicine mirrors the broader public conversation: it centers on balancing respect for patient autonomy against concerns about potential abuse, the role of physicians, and the adequacy of palliative care alternatives.
