There is a difference between a right and an exercise of a right
Exercises of a right fall into two catageories: Protected and Non-protected
Protected: Any exercise of a right that is not in the Non-Protected group
Non-Protected: Any exercise of a right that causes infringment of other peoples rights.
This is the legal definition, though not in legalese. Smoking is a Non-Protected right technically, yet everyone forgets that fact and wants to lump it in with Protected rights. This is merely because anyone who could and would make the argument get's stonewalled by people with billiobs more dollars than them. People who make money of letting other people kill themselves and poison others.
You do not have a right to smoke --- Period

Bobboau: That is why libertarians are naivfe, they do not differentiate between Protected and Non-protected rights, under their ideas you can abuse other peoples rights so long as you are exercising your own, so I guess I can beat people up randomly because I am exercising my right to happiness, even though I'm violating their right to happyness, and right to bodily integrity.
That's where the Libertarian view of what rights are leaves you. Libertarianism is one step from anarchism, and anyone who thinks anarchism can work and have everyone equal, unabused, etc is just downright foolish. Furthermore anarchism will never remain pure for more than 5 minutes, someone will start trying to carve out control and will form some other kind of control mechanism, probably authoritarian, even if they do not call it a government
