Physician assisted death is a practice in which a doctor prescribes a lethal dose of medication to a terminally ill patient who then takes it themselves to end their life. The key distinction is self-administration: the patient, not the doctor, performs the final act. In the United States, this is most commonly called “medical aid in dying,” while legally and ethically it remains distinct from euthanasia, where a clinician directly administers the lethal medication.
How It Differs From Euthanasia
The terms surrounding end-of-life practices can be confusing, and the distinction matters both legally and practically. In physician assisted death, a doctor writes a prescription, but the patient decides when (or whether) to fill it and when to take it. In euthanasia, a healthcare provider directly administers the medication, typically through injection. Both practices fall under the broader umbrella of “assisted death,” but most U.S. laws only permit the self-administered version.
This difference shapes the entire experience. A patient receiving a prescription for aid in dying retains full control over the timing. Many people who receive prescriptions never use them. In Oregon, which has tracked this data since 1997, 607 people received prescriptions in 2024, but only 376 died from ingesting the medications. Some patients find comfort simply in knowing the option exists.
Who Qualifies
Every jurisdiction that permits medical aid in dying imposes strict eligibility criteria. While specific rules vary by location, the core requirements are consistent: the patient must be a mentally competent adult with a terminal illness expected to result in death within six months. The patient must also be a resident of the state or jurisdiction where they’re requesting the prescription.
Mental capacity is a central safeguard. If a prescribing physician has any concern that a mental health condition might be impairing the patient’s judgment, they are expected to refer the patient for a psychiatric or psychological evaluation before proceeding. The goal is to ensure the request reflects a clear, sustained decision rather than a response to treatable depression or temporary distress.
The Request Process and Safeguards
Getting a prescription is not a single conversation. U.S. laws build in multiple steps designed to confirm that the patient’s decision is voluntary and consistent over time. In Colorado, for example, the patient must make two separate oral requests at least seven days apart, along with a written request witnessed by at least two other people. If the patient’s prognosis is less than 48 hours, the two oral requests can happen at the same time.
These waiting periods serve as a cooling-off mechanism. The patient can withdraw the request at any point, and no one is obligated to follow through. The process also typically requires confirmation of the terminal diagnosis from a second, independent physician.
Where It’s Legal in the United States
Ten U.S. states and the District of Columbia currently have laws permitting medical aid in dying. Oregon was the first, passing the Death with Dignity Act in 1994 (it took effect in 1997). Washington followed in 2008, Vermont in 2013, and California and Colorado both passed laws in 2015 and 2016 respectively. Hawaii, Maine, New Jersey, and New Mexico enacted their laws between 2018 and 2021. The District of Columbia passed its own version in 2016.
Each state uses a slightly different name for its law. California calls it the End of Life Option Act, Hawaii uses Our Care, Our Choice Act, and New Jersey titles its version the Medical Aid in Dying for the Terminally Ill Act. Despite the different names, the fundamental framework is similar across all jurisdictions.
Where It’s Legal Internationally
Outside the United States, the legal landscape is broader and, in some places, permits more than just self-administered medication. Euthanasia (where a clinician administers the lethal dose) is legal in the Netherlands, Belgium, Luxembourg, Colombia, Canada, New Zealand, five Australian states, and Spain. Switzerland and Austria permit physician assisted suicide but not euthanasia.
The eligibility criteria differ significantly by country. Most laws restrict the practice to people with terminal physical illnesses, but the Netherlands, Belgium, Luxembourg, and Canada (as of 2023) allow requests based on psychiatric illness or dementia, provided the patient is still competent to make the decision. This is a major point of divergence from U.S. laws, which limit eligibility to people expected to die within six months from a physical condition.
Why Patients Choose It
The reasons people request assisted death are more varied than many assume. Physical suffering is the most common motivation, but it’s not the only one, and often not the primary one. In a Canadian study of 112 people who had assisted deaths, about 60% listed disease-related symptoms like pain and nausea as one of their top two reasons. But 53% cited loss of control and independence, and 49% pointed to losing the ability to do activities they found enjoyable or meaningful. About 24% cited fear of future suffering.
These numbers reveal something important: the decision is often less about escaping current pain and more about preserving a sense of agency and dignity in the face of decline. Many patients are already receiving palliative care and still choose this option because of what their illness is taking from them beyond physical comfort.
What the Medical Profession Thinks
The medical community is not unified on this issue. The American Medical Association maintains that physician assisted suicide is “fundamentally incompatible with the physician’s role as healer” and that it would pose serious societal risks. This is an active stance of opposition, not neutrality.
That said, the AMA also acknowledges that individual physicians who participate in legally authorized aid in dying after careful moral consideration will not have violated the AMA’s Code of Medical Ethics. In every U.S. jurisdiction with an aid-in-dying law, physicians can refuse to participate. No doctor is required to write these prescriptions, and many healthcare institutions, particularly those with religious affiliations, do not permit the practice within their systems. Patients who are denied by one provider must find another willing physician on their own.
What Happens Medically
The medications prescribed for aid in dying are designed to cause deep unconsciousness followed by death. In U.S. states, doctors commonly prescribe combinations of sedatives, heart-stopping agents, and pain medications. The two most frequent combinations are known by their abbreviations DDMA and DDMP, which contain a mix of a sedative, a cardiac medication, a pain reliever, and either an antidepressant or a blood pressure drug. Oregon and New Jersey tend to use one combination, while Colorado and Hawaii favor the other.
The patient takes the medication orally, usually mixed into a liquid. Death is not always rapid. With some drug combinations, more than half of patients experience a dying process that lasts longer than one hour. The patient loses consciousness quickly, but the time between unconsciousness and death varies. Anti-nausea medication is typically included or taken beforehand to prevent vomiting, which could interfere with the dose.
This variability in timing is one of the ongoing clinical challenges. Families present at the bedside should be prepared for the possibility that the process takes longer than expected, even though the patient is not conscious or in distress during that time.
