How many chemicals could possibly be packed in one tiny cigarette that you so casually smoke every hour?
Its 8,400 -10,000 chemicals present in cigarettes
Cigarettes look deceptively simple, consisting of paper tubes containing chopped up tobacco leaf and it will deliver a steady dose of nicotine. In addition to nicotine the following components also present
PVA glue and
Cellulose acetate-based filter
Additives are used to make tobacco products more acceptable to the consumer.
Humectants [glycol or glycerol]
Some of the above components are harmless, but along with that 600 permitted additives are burned in cigarettes.
Every smoker should see the following list of chemicals that are present in smoke
How much can these dangerous chemicals harm you?
In low doses stimulates
Central nervous system
Increases the heart beat rate and blood pressure which further leading to the heart needing more oxygen
Stimulate abnormal proliferation of vascular endothelial cells
Induces potentially atherogenic genes in human coronary artery endothelial cells
It causes microvascular injury
Carbon monoxide is the main poisonous gas in car exhausts as well as present in cigarette smoke
It binds to haemoglobin much more readily than oxygen, thus causing the blood to carry less oxygen.
Not just tobacco, there are several harmful chemicals in cigarettes, some of which are poisonous
Other chemicals effect include
Chemicals Normal usage
Arsenic Used in rat poison
Methane It is a component of rocket fuel
Ammonia It is a component of rocket fuel
Cadmium Used in batteries
Formaldehyde Body tissue preservation chemical
Hydrogen Cyanide the poison used in gas chambers
First, Second & Third hand smoking types
The inhalation of smoke of burning tobacco encased in cigarettes, pipes, and cigars.
Smoking will shorten life and leads to cancer as it blackens lungs
Secondhand smoke is the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers. Secondhand smoke contains more than 7000 chemicals.
It has immediate adverse effects on
Blood and blood vessels
Thirdhand smoke is contamination by tobacco smoke that lingers following the extinguishing of a cigarette. Studies show that thirdhand smoke clings to hair, skin, clothes, furniture, drapes, walls, bedding, carpets, dust, vehicles and other surfaces, even long after smoking has stopped. Thirdhand smoke residue builds up on surfaces over time and resists normal cleaning.

Chemicals are in everything we see, and the reactions between them can look like anything from rust on a spoon to an explosion on your stovetop. But why do these reactions happen in the first place? Kareem Jarrah answers this question by examining the two underlying forces that drive both endothermic and exothermic chemical reactions: enthalpy and entropy.
