Tobacco is a central nervous system stimulant drug. One of its components, nicotine, has an enormous additive capacity, and is the reason why its consumption produces dependence.

The results of the exhaustive scientific research carried out so far confirm that more than 4,000 different toxic products are produced during the combustion of tobacco. Among them, the following stand out due to their special danger and the diseases they can be associated with:

• Renting agents: used to pave roads and streets. They are responsible for different types of cancer.

• Arsenic: very powerful deadly poison: carcinogen.

• Cadmium and nickel: Used in batteries: carcinogen.

• Vinyl chloride: vinyl records: carcinogen.

• Creosote: tar component: carcinogen.

• Formaldehyde: organic preservative used in forensic laboratories and pathology: carcinogen.

• Polonium 210: radioactive: carcinogen.

• Urethane: used for packaging; carcinogen.

• Carbon monoxide: promotes cardiovascular diseases. Fatal in closed spaces when there is poor combustion (boilers, stoves, braziers,…).

• Ammonia: Used in window cleaners.

• Acetone: toxic solvent.

• Acrolein: Powerful bronchial irritant and cause of emphysema.

• Hydrogen cyanide: Deadly poison used as a rodenticide

• Methanol: Used as missile fuel.

• Toluene: Toxic solvent

• Hydrocyanic acid: responsible for respiratory diseases such as chronic bronchitis and pulmonary emphysema.

• Nicotine (C10 H14 N2): causes tobacco dependence. It has an approximate half-life of two hours, but as its blood concentration decreases, the desire to smoke increases.
