A firearm is one of the best options, but it's a little difficult to get, gases are easier. Some inhalation techniques should work much more reliably and faster than using SN. In terms of sensations, everything depends on the gas. If this is, say, a readily available propane-butane mixture with a fragrance, then the fragrance may be somewhat irritating, but SN can hardly be called tasty either. In terms of taste and smell, they are most likely equally unpleasant, plus or minus. If it is an inert or semi-inert odorless gas such as nitrogen, then there are no unpleasant sensations, SN is immediately a loser. The top option is nitrous oxide, you can even get a last kick with it.
I subscribe to every word. I would also add that the most decent people, who are really trying to do something useful for others, have long been squeezed out of all government structures, and now also from educational institutions. In the overwhelming majority, only opportunists remain there, for whom the main priority is to lick the asses of the bosses in order to sit in a warm place; they don't really care about the needs of the people.
As for the USA, it doesn't seem like everything is going smoothly there. Judging by what people living there write, in this country the prices for medical care are simply astronomical, and with a small income it may be easier for you to shoot yourself than to seek medical help.
There are also plenty of morons who pass moronic laws. Just look at the ban on abortion in some states. Like, once you get pregnant, you're welcome to be the incubator and the mother of the baby, and we don't care what you want, we've already decided everything for you. This is also a kind of dictatorship, isn't it?
