Why Is Smoking Bad For Your Health

smoking is the only legal consumer product that kills you when you use it exactly how it's meant to be used! That's pretty scary, isn't it?

Cigarettes are made from tobacco. The tobacco plant is the only plant ever discovered to contain the drug called nicotine. Nicotine is a very strong poison that can kill a human in less than an hour if even a small amount is injected into the blood-stream. Tobacco smoke contains very tiny amounts of nicotine that aren't deadly, but are still very bad for our health.

Tobacco smoke also contains many other chemicals. In fact, it contains over 4,000 chemicals, many of which are very harmful to our bodies. All of these chemicals mix together and form a sticky tar . It's the tar that gives cigarette smoke it's smell and colour. The tar sticks to clothing, skin, and the insides of our lungs!

Tar is very dangerous inside our lungs. It sticks to the cilia in our lungs that are responsible for sweeping out germs and dirt. If the cilia are covered in tar, they can't work right, and germs and dirt can stay in the lungs and cause diseases.

The damage tar does to your cilia is only the beginning, though. The tar and smoke are made up of many chemicals that are known to cause cancer, as well as many chemicals that are just plain bad for you. Just a few of these chemicals are:

Carbon Monoxide	Nitrites
Ammonia	Nitrosamines
Hydrogen Cyanide	Sulfur Compounds
Vinyl Chloride	Hydrocarbons
Volatile Alcohols	Urethane
Formaldehyde	Hydrazine

With the nicotine and tar working together, there are a lot of bad diseases linked to smoking cigarettes. Diseases like throat cancer, mouth cancer, bladder cancer, lung cancer, chronic bronchitis, emphysema, and heart disease are all caused by smoking.

Each cigarette you smoke takes 5 to 8 minutes of your life. Is it worth it?

Unfortunately, even if you don't smoke, you can still get sick from tobacco smoke. If you breathe the smoke from another person's cigarette, it's as bad as if you were smoking the cigarette yourelf! This smoke is called second-hand smoke and it kills hundreds of people each year in Canada. If your parents smoke, you have a greater chance of getting ear infections, asthma, bronchitis, and tonsillitis .

Children who are exposed to smoke all their lives have underdeveloped lungs, and they are two to four times as likely to have allergic reactions and asthma than children of non-smokers.
Second-hand smoke is starting to really bother non-smokers, and that's why there are more places where smoking isn't allowed than there used to be. Now you aren't allowed to smoke on a plane, in a bus, or in many buildings. Non-smokers want to breathe clean air!

Cigarettes aren't just bad for our health. They are bad for the environment, too! Think of the amount of paper that goes into making each cigarette. Canadian youth smoke about 6,000,000 cigarettes per day! That's a lot of trees that are cut down, and the paper can never be recycled!

Look around outside. There are cigarette butts everywhere! Do you know that it takes more than 5 years for a cigarette butt to biodegrade? That means that it takes at least 5 years for the cigarette butts to break down, unless someone cleans them up. Gross!

People are starving all over the world. If the land used to grow tobacco was used to grow food instead, we could feed another 10 to 20 million people! What do you think is the better thing to grow?
