The "problem" with the commercial is that it doesn't do anything to build up the awareness on why smoking is bad. It only explains statistical relationship with smoking (for example smoking causes lung cancer, or X amount of people will die from Y this year)... never the actual problem with individuals and smoking. Heck, I could explain a million reason on why fast food is bad for the population by bringing up childhood obesity, heart problems, etc. But all that isn't going to convince you, since you yourself may never experience any of those problems... same thing with these smoking commercial ads.
