That picture isn't BS though, and no one said anything about a leg. You are right in that we shouldn't lie or exaggerate these things because then it just makes people not trust, but that mouth cancer is a real thing. And it is a real slow and real painful way to die.

People talking like you, saying something isn't real and then using your own speculation as evidence (when tobaco does in fact cause mouth cancer, and can get worse than that photo). That's how people become misinformed. No one ever said tobacco makes your legs fall off, you just made that up. That's how people become misinformed, by doing exactly what you are doing. Don't just speculate and then use your own speculation as a fact. No one said anything about a leg, you just made that up, and now you're saying that it's wrong to lie about people losing their legs. You are causing misinformation, you are not preventing it.

I hope you never have the proof that I have experienced. I don't want anyone to watch the horrors of mouth/lung cancer take over the life of someone they love. Especially when they are the ones who caused it on themselves. I tried to make them stop smoking for years, if only they had a little more convincing..... But luckily they did not lose their legs, that would be horrible!
