Medical aid in dying refers to a practice where a terminally ill patient, who is experiencing unbearable suffering, can request and receive assistance from a physician to end their life. This process typically involves the patient taking prescribed medication that leads to a peaceful death, ensuring they have control over their end-of-life experience. This practice is legal in several regions, including some states in the United States and countries like Canada and the Netherlands. Strict eligibility criteria and procedural safeguards are usually in place to ensure that the decision is voluntary, informed, and made by a competent individual.
