Would you really end up in prison for buying N for suicide? You can always travel.
I really doubt low hanging is more peaceful. Sounds like a bad way to go. Something you do because of lack of access to something better. Have you tried choking yourself? People doing this have balls of steel.
Still, the question was. Is freezing to death outside preferable? I guess once you fall asleep, if you do not wake up, you simply die.
I agree that euthanasia should be available. But that will not happen. Especially to people without medical issues deem worthy of suicide by majority of people and most suicides do not fall into the category.
The only reliable and easily arranged, but not cheap, method for peaceful exit might be inert gas. Also it takes time to arrange and you need suitable place. I suppose I could do it at workplace. But I dislike that place and I do not want to die there.
I have done a practice run and it's actually extremely peaceful, you fade out very quick. At least I can only speaek for partial, without any drops. The trouble is being able to find the right spot and a strong rope/anchor point that won't give. It's trickier than it seems, but when done right yes, I would argue it's peaceful compared to other methods. You have to have all the variables in place to prevent discovery though. It's not a super easy one and done thing, takes planning and practice. Many people can never find the right spot and pressures sbuilds up from the jugular being blocked rather than the carotid and THAT is gnarly.
and yes lol, you could absolutely end up in prison for N. There is no country that has it guaranteed easily available either so your whole trip might be for nothing.
I would definitely say freezing is preferable over drowning if that was your question. However as others have mentioned there are SO many variables with how long it takes, there's always the chance of waking up somehow once the drugs wear off and having such bad frostbite you lose a limb or some shit so consider that too (I know all methods have consequences if failed, just bringing them up so you can make an informed decision._
I too was very intereseted in inert gas, however I fucking suck at putting shit together, and I don't live alone so I doubt I could sneak up and hide a nitrogen tank with nobody noticing, unfortunately.
