This is old info. You can't find N in Tijuana, in fact, it's hard to find N in Mexico. One user told me he tried to get N in Mexico (he is from there) and he was unsuccessful. It's not that easy as they make it out to be.
I'm pretty sure, it depends on where you go and how you try to get it in Mexico... Obviously, you can't just walk into any pharmacy and be like "Hey, I need some N to kill myself." Pro suffering people are everywhere in this world and some of them probably can't be bribed unless you have a shitload of money.
True, it's not easy at all. You have more chance of finding a mugger who can shoot you than finding N.
But at least in countries like Mexico, you have a chance that isn't 1 out of 1000000. Trying to find N in your average Western world country would be like trying to find the holy grail.
Mexico is nothing like that, it's just like that because people don't care about laws as long as they can make money. They are very much pro-life and catholic.
The whole world is pretty much pro suffering and
