Cigarette filters do not protect smokers from more than 50 carcinogens, including cyanide and arsenic, which are in tobacco products.
The smoke from pipes and cigars also causes serious health consequences.
Cigars contain significantly more nicotine
and produce more tar and carbon monoxide than cigarettes.
The harmful chemicals of smokeless tobacco are absorbed into the body at levels up to three times the amount of a single cigarette.

environmental tobacco smoke (ETS)
mainstream smoke
sidestream smoke
Healthy People
Tobacco smoke can harm nonsmokers.
Nonsmokers who breathe air containing tobacco smoke are also at risk for health problems.
Environmental tobacco smoke (ETS) is also called secondhand smoke.
Environmental tobacco smoke (ETS)Air that has been contaminated by tobacco smoke
Environmental tobacco smoke is composed of mainstream smoke and sidestream smoke.
Because mainstream smoke has been exhaled by a smoker, it contains lower concentrations of carcinogens, nicotine, and tar.
Mainstream smokeThe smoke exhaled from the lungs of a smoker
Sidestream smoke is more dangerous than mainstream smoke.
Sidestream smokeThe smoke from the burning end of a cigarette, pipe, or cigar
ETS from cigarettes, cigars, and pipes contains more than 4,000 chemical compounds.
More than 50 of those chemicals are
cancer-causing carcinogens.
ETS causes eye irritation, headaches, ear infections, and coughing.
It worsens asthma and other respiratory
problems, and it increases the risk of lung cancer and coronary heart disease.
Smoking during pregnancy reduces blood oxygen levels, increasing the risk of
impaired fetal growth
spontaneous miscarriage and prenatal death
premature delivery
low birth weight
deformities
stillbirths
Infants exposed to ETS after birth are twice as likely to die of SIDS.
They may have severe asthma attacks,
ear infections, or respiratory tract infections.
The children of smokers are more than twice as likely to smoke themselves.
They also have a higher incidence of sore throats ear infections upper respiratory problems
Parents protect the health and development of their children by staying tobacco-free.
