Tar yes, the same thing they use to pave streets and driveways. Ever notice how smoker’s teeth are yellow? Tar is responsible for that.
Hydrogen Cyanide This chemical is used to kill rats.Of course no one would willingly inhale this chemical which, under the name of Zyklon B, was used as a genocidal agent during World War II, but smokers do it multiple times with every cigarette they light. Because hydrogen cyanide is present in second hand smoke, nonsmokers are also at risk.
Hydrogen cyanide at room temperature is a volatile, colorless-to-blue liquid (also called hydrocyanidic acid). It rapidly becomes a gas that can produce death in minutes if breathed.
Benzene This chemical is used in manufacturing gasoline.
Acetone It’s in nail polish remover and it’s in cigarettes. Yum!
Formaldehyde This is what they use to preserve dead bodies. It’s also used as an industrial fungicide, is a disinfectant, and is used in glues and adhesives. It is classified as a human carcinogen (cancer-causing substance) by the International Agency for Research on Cancer, and as a probable human carcinogen by the U.S. Environmental Protection Agency(EPA). According to an article in the American Journal of Public Health from November of 1982, formaldehyde in sidestream cigarette smoke is evident in concentrations of up to three orders of magnitude above occupational limits, which readily accounts for eye and nasal irritation. "Low-tar" cigarettes appear at least as irritating as other cigarettes. More than half the irritant is associated with the particulate phase of the smoke, permitting deposition throughout the entire respiratory tract and raising the issue of whether formaldehyde in smoke is associated with bronchial cancer(1).
Ammonia We use this chemical to clean our houses. The process of using ammonia to boost the impact of nicotine on the user is called "free-basing." Similar to the chemical process of free-basing cocaine, the end result is an enhanced effect of the drug. Nicotine exists in two forms, acid and base. When ammonia is added, it reacts with the acid form of nicotine in a cigarette and converts it to the base form. The base form vaporizes more easily from the smoke particles into a gas phase. As a gas, nicotine will deposit directly on lung tissue and begin to circulate immediately throughout the body.
Carbon Monoxide It’s in car exhaust, and it’s in cigarette smoke.
It's a colorless,odorless gas that is produced as a result of incomplete burning of carbon-containing fuels. Exposure to CO reduces the blood's ability to carry oxygen. Cigarette smoke can contain high levels of CO, as well as 200 other known poisons.
Breathing low levels of CO can cause:
fatigue
increased chest pain in people with chronic heart disease
In otherwise healthy people, breathing higher levels of carbon monoxide causes flu-like symptoms such as:
headaches
dizziness
weakness
sleepiness
nausea
vomiting
confusion
disorientation
...after reading this...do you still want a cigarette?
