Also, catching the bus in this modern day and age is kind of traumatic any way you slice it, but The Government is with holding the most peaceful and natural seeming methods from so many citizens who are suffering. It shouldn't be a moral issue; yet the majority still show their moral biases toward the act and subjects who commit the act of suicide by standing on a moral high ground, and declaring everyone who is born into life should have to live it out, without questioning whether life is something they would have signed up for in a sane mind.
SN and N are about the softest methods available, and one isn't very available to many people anymore(from my understanding), and SN is probably going to get harder to obtain in pure form. It will just cause more of a headache to obtain pure material. It shouldn't be the case.
...Many people will decide to jump or hang if that's their chosen or sole option, and again The Government of the world are afraid to provide adults with legal euthanasia! Some will decide on hard methods for more nefarious reasons I'm sure, in protest of the lack of movement on the issue of clean human euthanasia. In countries where Healthcare is universal, imo, it should be free, not 10k+. People all over shouldn't have to slave to obtain a peaceful death, and I'm sure some people don't have the mind too anyway.
Life is given freely, it should be taken away the same way. Maybe a small payment for the ingredients...laws should be in place to make sure the market price for the N, and other gear for human euthanasia should be protected from market inflation in some way.
