Suicide bag

A suicide bag, also known as an exit bag or hood, is a device consisting of a large plastic bag with a drawcord used to commit suicide. It is usually used in conjunction with an inert gas like helium or nitrogen, which prevents the panic, sense of suffocation and struggling during unconsciousness (the hypercapnic alarm response) usually caused by the deprivation of oxygen in the presence of carbon dioxide. This method also makes the direct cause of death difficult to trace if the bag and gas canister are removed before the death is reported. Right-to-die groups recommend this form of suicide as certain, fast, and painless, according to a 2007 study.
