This may come off so insensitive but I can't help but think of DWUW when people on here write "people can do what they want with their body".
OT: It should not be illegal. People should get proper help if they fail but not some kind of prison sentence wtf. Of course if you knowingly endanger other persons with your attempt, that's obviously a big cry for attention but neither should be punished just for the simple fact that as soon as they get out, they will try again. But then again, drug dealers don't stop dealing after they served a certain time in jail.
