What’s in a cigarette?
Do you actually know what’s in a cigarette? A cigarette may look harmless enough and you might think it’s just some tobacco leaves covered in paper but it actually is a stick containing lots of poisonous chemicals. When a cigarette burns it release up to 4,000 toxic chemicals all which are lethal to the body. We know that 60 of these chemicals can cause cancer.

Myths and Facts about Smoking
1. Smokers live just as long as non-smokers
MYTH! Smokers on average lose 10-15 years of potential life (Source: Doll and Peto, 1994)
2. Smoking won’t affect my health until I’m much older
MYTH! Even smoking a little can cause damage. Research has shown that even "occasional" smoking, smoking only a few cigarettes per day, or smoking "without inhaling" can increase your risk of heart disease and shorten your life. Smoking causes bad breath, wrinkles and ageing of the skin in young people.
Another problem with smoking "just a little" is that most people can't do it for long. Cigarettes are physically addictive. Because cigarettes are addictive, most people can't continue to be occasional smokers for long. Soon, they find themselves smoking every day, several times a day. And the more they smoke, the more they are damaging their health.
3. Smoking is bad for your heart
FACT! Smoking increases the risk of heart attack, stroke, arthrosclerosis and CPOD. Short term smoking increases teenagers heart rates by 2-3 beats per minute at rest compared to teens who don’t smoke.
4. Smoking is a personal choice
What do you think? Some people say smoking is a personal choice and you choose to smoke every time. Other people think that once you are addicted to nicotine, it is not a personal choice and that’s why we need to regulate things like marketing, displays, smoking indoors. Also people who breathe in other peoples smoke don’t do it by choice and are involuntarily having their health affected.
5. 50% of lung cancer cases are caused by smoking
MYTH! 95% of lung cancer cases are caused by smoking or second hand smoke. It is rare for someone to have lung cancer who has never smoked. Quitting smoking decreases your risk of developing lung cancer. The longer since you've quit, the greater the decrease in risk.
6. Smoking keeps you thin
MYTH! Smoking doesn’t make you thin. Many people, especially young girls, believe smoking makes them lose weight and keeps them thin. Smoking kills your taste buds and smell and therefore food may not be as appealing, but there is no evidence to show that smoking makes you lose weight.
7. Nicotine is the only dangerous chemical found in cigarettes
MYTH! There are over 7,000 different and dangerous chemicals in cigarettes with over 69 of them known to cause cancer.
- arsenic (found in rat poison)
- ammonia (found in bleach)
- DDT (found in insecticide)
- methanol (found in plane fuel)
- hydrogen cyanide (found in poison in gas chambers)
8. A smoker will be just as fit as a non-smoker when playing sports
MYTH! It is a well-known fact that smoking reduces fitness levels. Carbon monoxide found in cigarettes replaces oxygen in the body which makes it harder for the body to function especially during exercise. Smoking replaces vital oxygen which needs to be absorbed into the blood and muscles. Inhaling smoke also restricts the airways and makes it harder for the person to breathe and take in oxygen. Oxygen is the fuel we need to create energy to keep running, exercising etc! Smoking also increases the heart rate which during exercise can impact on fitness.
9. A nicotine addiction has similar chemical characteristics to a heroin addiction
FACT! Research has shown that how a smoker addicted to nicotine behaves, is similar to a person with a heroin addiction. A person grows a nicotine receptor in their brain which they have to feed regularly with a cigarette as the body will crave it. When a person inhales it takes just 7 seconds for the nicotine to reach the brain. That is why a person has withdrawal symptoms when they quit smoking as the body is craving a hit.
10. Thirty per cent of cancers worldwide are caused by smoking
FACT! Smoking is responsible for 30% of all cancer cases worldwide. Every year in Ireland almost 6000 people die due to smoking related illnesses. 16 people die every day from smoking in Ireland. Tobacco kills more than 7 million people each year.
11. Rollies are healthier than normal cigarettes
MYTH! Some people mistakenly believe that Roll-your-own cigarettes are less harmful than factory made cigarettes. This could be because they think that loose tobacco is more "natural". However, many of the 7000 chemicals in cigarette smoke come from burning the tobacco itself. These include tar that causes cancer. Researchers believe that rollies are as harmful as or even more harmful than smoking factory-made cigarettes!
Peer pressure and smoking
We all know someone who smokes and most of the time people begin to smoke because they are offered a cigarette. Young people often start to smoke because their friends smoke and they want to fit or they can be pressured by their friends to try smoking. Sometimes just trying a cigarette can lead to an addiction to smoking and years of trying to give up. Believe or not 70% of smokers in Ireland wish they never started and want to quit smoking.
