Smoking can cause numerous health problems including lung cancer. It can also cause family members to not want to be around you because of the smell of smoke on you and your clothes. Cigarettes contain over 400 toxins, 43 of which are known to cause cancer. 25% of high school students smoke and almost half of high school students have smoked at least once.
If you need to quit smoking, mentally changing your attitude is necessary. Instead of thinking about how it sucks not having cigarettes, think about the harm that they brought to you and the advantages to quitting. My mother used to smoke when she was in her 20's, yet she saw the right thing to do for her health and quit successfully.
