Second hand smoke is worse because it hasn't traveled through the "filter"... (i use quotes to indicate my sarcasm)

I have a cigarette every now and then but they really ARE bad for you. Tobacco itself isnt bad for you but its the chemicals they put in commercial cigarettes that are killing everybody. They are carcinogens, and everytime you inhale the smoke you are inhaling and exposing your lung to very bad chemical compounds...

This may sound a bit exaggerated... but you might as well wash your hands with Ethidium Bromide once a week for the rest of your life.
