Well see, thar ya go. It *was* the smoking that killed him. Don't you know that smoking causes everything now? Why, according to my doctor, it's because she's a smoker that my mother gained weight, then suddenly lost weight, then discovered that she has Grave's disease. It's also why she had terrible gum disease even though the gum disease started when she was living with her good, Christian parents (who never touched cigarettes or alcohol in their lives) when she was in her early teens. It's why she has hemorrhoids and why I have irritable bowel syndrome.

I've seen smoking blamed for breast cancer, breast lumps, cystic ovaries, diabetes, asthma, impotence, high blood pressure, low blood pressure, anal fissures (figure *that* one out), chronic constipation *and* diarrhea, weight gain, weight loss, hair loss, and even (you're not going to believe this one) ringworm. Yes, the doctor blamed a stubborn spot of ringworm on the fact that I smoked.
It's like all illnesses are somehow linked to cigarettes. And, in the case of my great aunt who died of lung cancer and never smoked in her life (actually, she had *no* risk factors), we were told, "I'm sorry, but these thing sometimes just happen." Trust me, if you smoke, nothing will ever "just happen" to you. It's all your fault.
There is way too little evidence for most of the claims. Especially about second hand smoke - the evidence is that it stirs up the immune system of some people.
On the other hand, my mother is trying to die from thymic carcinoma and the "paraneoplastic syndrome" that is left over, causing delirium, weakness, and pain. There are no risk factors for thymic carcinoma.
