"When used as intended by the manufacturer, tobacco WILL kill you"
Actually, no. Only 1 in 2 life-long smokers actually die from smoking, and that's ignoring those who quit at some point.
There's also a huge difference between smoking a few at the weekend and smoking 60 a day - which starts sounding like risk management if you're not careful. Oops.
Of course, the reason people smoke is that they're addicted to nicotine. I'm interested in your anti-addiction technique of calling people stupid, but I'm not sure it works in practice.
