I answered "No" because there are many other kinds of methods available. For me, my method would be the firearm because I couldn't get things shipped to my place (my parents' home) without them knowing. That's just speaking for me and maybe some others in similar situations. As for the other kinds of methods people go for they include: jumping, hanging, starvation, freezing, inert gases, just to name a few of the other ways people CTB.
