In spite of all the health warnings, teenagers continue to start smoking even though they all know it's bad for them. Young people start smoking for many reasons - to act older, fit in, because of peer pressure or to rebel.

Parents who make it clear that they disapprove of smoking have more influence on their children than they might think.

It's never too early to bring up the topic of smoking. Most kids who smoke say they tried their first cigarette at 13 or younger!

Establish rules. Talk about family expectations and rules about smoking, clearly stating and enforcing the consequences for breaking these rules.

Know the facts. Talk with your son/daughter about the dangers of smoking. Teenagers often don't relate to the future health problems caused by smoking, such as lung cancer and heart disease.

Cigarette smoking can cause shortness of breath, which could interfere with sporting or other physical activities.

Let your teenager know how smoking can stain teeth, cause bad breath, lead to yellow fingers, smelly hair and clothing, as well as causing premature ageing.

If you smoke, try to quit. If you smoke, your teenager is more likely to become a smoker.

Be honest. Do you smoke or are you an ex-smoker? You can still express concern over your child starting the habit. Talk about how hard it is to give up. Share your experiences.
