What i mean is that you hear that 2nd hand smoke kills X amount of people a year. How do they figure that out? If 2nd hand smoke is so powerful wouldnt you get addicted to it.
[edit] re adicted to 2nd hand smoke: see the earlier comment from somehone else. No is the short answer.
below is in answer to your first 2 sentences.

That's actually a tough one. The results that X (whatever it is) people die from second hand smoke is hotly contested.
It's one of these
probable rather than definite statistical things that leaves people enough room to let their bias affect which way they lean on it. It's difficult to prove conclusively because of confounding factors (like everybody is genetically different, has different lifestyles, etc) that make it quite difficult to tease out effects this small (yes small - after all only a small fraction of smokers die as a direct result of smoking, an unknown number get sick, live shorter lives etc, very messy stuff to prove conclusively). It's also a politically (economically) hot point as well, leading to lobby groups and research teams who actively try to discredit any negative research, publicity etc for economic rather than purely search-for-knowlege reasons - that doesn't happen (to the same extent) for other forms of air pollutions with similarly suble effects.
For me an easy distinction is:
Drinking beer increases your chances of getting X cancer by Y amount. But I like to drink.
Eating barbequed food increases your chances of getting M cancer by N amount. But I like BBQ, I'm australian (see drinking)
Being exposed to 2nd hand smoke increases your chance of getting A cancer by B amount. But I hate cigarette smoke...
It's ok if it's my choice.

I dont see it as a health issue as much as a nusance issue. No one is stopping you from smoking. Just do it outside instead of in my face while Im eating. Why should my clothes stink like cigarettes. If i threw beer on you should i be "ah well, you chose a restraunt where there's beer."
Yeah. The nuisance issue is more easily quantified. I go to a bar - my eyes sting, I cough, I go home stinking of smoke. Easy.
