Physician-assisted suicide (PAS) is a highly controversial concept, only legal in a few countries. In PAS, physicians, with voluntary written and verbal consent from the patient, give patients the means to die, usually through lethal drugs. The patient then chooses to "die with dignity," deciding on his/her own time and place to die. Reasons as to why patients choose PAS differ. Factors that may play into a patient's decision include future disability and suffering, lack of control over death, impact on family, healthcare costs, insurance coverage, personal beliefs, religious beliefs, and much more.
