What really goes into a cigarette?

Over two billion people in the world are smokers, which is around a third of the world’s population. Although the number of people smoking in Britain has halved over the last 50 years due to numerous health-awareness campaigns, many are still spending thousands of pounds each year on cigarettes, with very few actually knowing what goes into them.

Shockingly a single cigarette contains over 4,000 chemicals, around 70 of which are known to be cancerous, according to cancer research.

Most of us are aware that cigarettes contain nicotine, tobacco, tar and other toxic chemicals but what are they and what implications can they have on our health?

Here is a breakdown of some of the most well-known chemicals often found in cigarettes:

Nicotine- found naturally in tobacco, nicotine is a strong poisonous drug that in its purest form could kill a human with a single drop, and is just as addictive as heroin or cocaine. Often used in pesticides and bug sprays this is a toxic chemical and takes just 10 seconds for the drug to reach your brain from inhaling cigarette smoke.

Tar- a mixture of lots of chemicals, this forms a sticky brown residue that sticks to the lungs and stains smoker’s fingers and teeth.

Tobacco- is a green, leafy plant that is grown in warm climates. After it is picked, it is dried, ground up, and used in different ways. It can be smoked in a cigarette, pipe, or cigar.

As well as tobacco, other chemicals are added to form a cigarette. More than often, these are toxic. Here is the list of harmful chemicals that are typically found in cigarettes:

Arsenic- often used in wood preservatives.
Cadmium- used in batteries.
Chromium- used to manufacture dye, paints and alloys.
Acrolein- used to be used as a chemical weapon.
Polonium 210- this is a highly radioactive element.
Carbon Monoxide- found in car exhausts and is extremely dangerous.
Ammonia- a chemical used to make fertilizers and explosives.
