If people want to engage in a disgusting habit like smoking, they are free to do it in the privacy of their own homes. However, the rest of us should not be subjected to the stench or health risks from such a foul habit. All public spaces should be smoke-free. Why should we have to suffer from someone else's addiction? In my experience, the majority of smokers are selfish and believe they have the right to smoke, regardless of the harm they cause to others.
