WEIRD< okay I smoke, yeah not good, for sure. BUT I started using tar blocker tips, and it is SO cool because it has drastically cut my smoking down in the last few days, and my friend is using them. ALSO DISGUSTING how much tar is in each one. You can see it in the tips, HERE is what I was thinking, says it pulls out most chemicals....SO maybe the chemicals also is what causes folks too smoke so much more. Freaking interesting. Maybe just maybe I will end up whipping this habit.
