Smoking Ban in Michigan

Recently the Michigan House and Senate passed a smoking ban in public places. This means that there will be no smoking in resturants and all bars except for casinos and cigar bars. I think that the smoking ban is really stupid. Ill admit i am a smoker, but i think smoking should at least be allowed in public places. So in May it will be illegal to smoke outside your house, or walking to class, or anywhere that is not on your property. A Question i have is, how come its okay to smoke on your own property, but a bar owner cant smoke in his bar, or allow people to smoke there? I just think it is going to causee a lot of problems and people are going to be fined for something that is harmless. I know smoking is bad for you, and i know people who dont smoke hat the smell of the smoke, or hate being next to someone when their smoking. I just believe it is a violation of rights, im not whining im just venting because theres nothing i can do about it.
