Does the first sentence go with with the statistic?

First and foremost, a cigarette contains more than 4000 harmful chemicals and it will kill you slowly. In fact approximately 80% of adult smokers started smoking before the age of 18. Every day, nearly 3,000 young people under the age of 18 become regular smokers. More than 5 million children living today will die prematurely because of a decision they will make as adolescents---the decision to smoke cigarettes.
