Carbon monoxide (CO) poisoning | Lost All Hope: The web's leading suicide resource. This is a brief explanation, the easiest method of those mentioned, and least expensive, is the burning charcoal method. The description talks about using it in a tend or a car, a hatchback is best. I am going back to find the specifics that I learned here a year and a half ago, but the very detailed method is hard to find. Basically and briefly, one lights a proper amount of charcoal (the right type may make the difference between failure and success), light it on fire and let it burn till it is no longer smoking; bring it inside a tent made of the proper material and sealed, or a van (hatchback) properly sealed, Some have done it in small bathrooms (sealed) or walk in closet. There is a megathread here with about 40 pages, I will return with the name, this time bookmark it for study.
FYI, there was a picture and article posted some time ago (perhaps still in the megathread) of an asian woman in her small tropical bedroom dead next to a bowl of charcoal, It was an incredibly peaceful scene. I've inquired about asian charcoal and was told it was made with less restrictions than that made in the US and therefore much more potent.
