Accumulates in lungs during smoking
Contains cancer causing chemicals
Hinders cell division of air sacs lumps of tissue
Blocks passage of air
Paralyzes cilia in air passages
Prevents cilia from removing dust - lungs, air tracts

Emissions of unfiltered gases
Studies - children who's parents smoke - children take in as if 80 cigarettes a year
