Why is it bad to smoke and take drugs?

Smoking is very unhealthy. It shortens your life by 7 minutes for every cigarette you smoke, it costs about $2,000 per year, it makes your teeth yellow and your clothes smell, and it?s addictive so people can't quit. Taking drugs is addictive too. It costs even more money than cigarettes, makes it almost impossible to get good grades or play sports, and can get you really sick. People who continue to take drugs often die young from taking them.
