Quitting is the only way to decrease your risk of these and other tobacco-related health problems. The addictive quality of nicotine, which is found in cigarettes, cigars and chewing tobacco, can make this especially difficult. That’s why it’s important to have a plan and a support network, people to help you stick to your plan. Write down your reasons for quitting. Exercising, chewing gum and keeping yourself occupied can help you quit. Talk to your dentist or doctor to see if the medications available would help you to stop using tobacco.
