We all have habits, good or bad. Some of them are a bit strange: reading magazines back to front, for instance. Others can be annoying: like biting your nails or being always late. You are lucky if you have only good and healthy habits: jogging every morning or brushing your teeth after meals. Unfortunately many people have bad habits which mainly cause serious health problems. The most common habits are smoking, drinking alcohol and using drugs. They usually come out as a result of some stress, anger or boredom. Some teenagers start smoking because they believe that it’s cool. Bad habits are dangerous and expensive. What is more, for many people they are addictive. It means that it’ll be very hard to quit them once you have started.

Cigarettes, alcohol and drugs can ruin someone’s life. For example, smoking damages lungs and causes cancer. By the way it is the number one killer in many countries today. About 90% of lung cancer patients developed their disease because of smoking. Chain smokers are also susceptible to heart diseases and strokes. Passive smoking is very harmful for surrounding people as well, especially for children and pregnant women. As for drinking alcohol, it can ruin your liver and kidney.  Besides, very drunk people and drug addicts become aggressive and violent. They can easily commit a crime under the influence of alcohol or drugs. Drunk driving is the main reason for car accident deaths in our world. Most bad habits have a great impact on people’s social life and their jobs.

Breaking the bad habits is the hardest thing to do. So it’s better not to start or try them at all. Scientists and doctors state that the way you treat your body in the first half of your life will affect how healthy you are in the second half of it. That’s why we should have only good and healthy habits. Our world would be a better place without cigarettes and drugs.
