whats inside??

There are more than 3000 chemical substances in tobacco's smoke. They are gas or liquid but they also exist as physical though microscopically small particles. List of cigerettes contents:

1. Nicotine

Nicotine is a powerful insecticide and poisonous for the nervous systems.Furthermore, there is enough (50 mg) in four cigarettes to kill a man in just a few minutes if it were injected directly into the bloodstream.Nicotine reaches the brain in just seven seconds, it stimulates the brain cells and then blocks the nervous impulse. Nicotine also causes accelerated heart rate, but at the same time it leads to contracting and hardening of the arteries: the heart pumps more but receives less blood.

2. Carbon monoxide (CO)

Smokers inhaling cigarette smoke breathe in 3.2% carbon monoxide – and directly from the source. Oxygen is mostly transported in blood by haemoglobin. When we smoke, however, the carbon monoxide attaches itself to the haemoglobin 203 times more quickly than oxygen does, thereby displacing the oxygen; this in turn asphyxiates the organism. This causes the following cardiovascular complaints: narrowing of the arteries, blood clots, arteritis, gangrene, heart attack, and also a loss of reflexes and visual and mental problems. It takes between six and 24 hours for the carbon monoxide to leave the blood system.

3. Tars

As the cilia (an organ for filtering and cleaning the lungs) are blocked by other irritants from the cigarette, the tars in the cigarette smoke are deposited and collect on the walls of the respiratory tract and the lungs, and cause them to turn black. So, just because a smoker is not coughing, it doesn't mean that he or she is healthy.The carcinogenic action of the tars is well known: they are responsible for 95% of lung cancers. It takes two days at least after cessation of smoking for the cilia to start functioning properly again, albeit only gradually. By smoking one packet of cigarettes every day, a smoker is pouring a cupful of these tars into his or her lungs every year (225 grams on average)

4.Others

More than 4000 irritating, suffocating, dissolving, inflammable, toxic, poisonous, carcinogenic gases and substances and even radioactive compounds (nickel, polonium, plutonium, etc.) have been identified in tobacco smoke. Some of these are listed hereafter: Benzopyrene, dibenzopyrene, benzene, isoprene, toluene (hydrocarbons); naphthylamines; nickel, polonium, plutonium, arsenic, cadmium (metallic constituents); carbon dioxide, methane, ammonia, nitric oxide, nitrogen dioxide, hydrogen sulphide (gases); methyl alcohol, ethanol, glycerol or glycerin, glycol (alcohols and esters); acetaldehyde, acrolein, acetone (aldehydes and ketones); cyanhydric or prussic acid, carboxyl derivatives (acids); chrysene, pyrrolidine, nicoteine, nicotinine, nicoteline, nornicotine, nitro amines (alkaloids or bases); cresol (phenols), etc.
