Second hand smoke is worse, because it is unfiltered, and the smoke you inhale into your body is slightly filtered. So, actually, if you breath in second hand smoke all day long, having never smoked in your life, you have a better chance of getting cancer, etc. then someone who chain-smoked all his life. No, the title of this thread is completely, absolutely dead wrong. I can find dozens of links to prove this, but it is not necessary . . .
Personally, I see doing drugs such as this just plain stupid. There are better ways to get high, and cigarettes are just chock-full of nasty chemicals, etc. No, there are better ways to get high, get the nicotine. Also, they are costly. It seems so silly when I see impoverished people buying cigarettes, when taht money could go to so many other, better places . . .
