But they're more technical to implement.
Yeah that's true but honestly the complexity is also not *that* big. You basically only need to learn how to hook up some things to a gas cannister. It's not something one just cannot learn, no matter how unhandy. I mean, I understand that many people who wanna do this are depressed and when you're depressed you're not exactly full of energy to do stuff and drinking some water with some powder sounds simpler then but on the other hand, this is the last thing you're gonna do, might as well invest some energy and thought into it. And it's really not that complex either. The parts you need are also not restricted, in any way. You'll always be able to buy them. Nobody's gonna ask questions. No welfare checks either because by the amount such parts are bought by private for all kinds of reasons, that'd tie up the entire police force. And it's defintively still simpler than IVs or jumping in front of a train (while the action itself might be simple, working yourself up to actually do it can't be, I can't believe it) and a plethora of other very unlikely methods which are being brought up on this forum every day. I mean, elderly people dying of cancer manage to do the exit bag.
Poisoning yourself and feeling the poison work until you die of the poison just sounds very unpleasant for me. With the exit bag, you more or less just pass out and don't wake up again.
