It's not illegal in the u.s. but you pretty much end up in jail because of it depending on how unprivileged you are. They force you into a hospital for however time they want to "protect you" often times giving you little to help and just throw you out and by that time you lost your job and some loose there housing and then become homeless because of it and then eventually jail for just trying to eat.
That's if you actually someone stops you before you do it. It's even worse if you survive the attempt.
Yes I know its not always like that. but from my experience with the system in Amerikkka and from others I know and used to know (RIP) this is how it pretty much works.
Please remember this is from my experience and people I know and know experience with. Suicide and attempting it.
Absolutely, freedom to choose what you want to wear and freedom of choice is incredibly important.
