This is especially true when the adolescents are exposed to the habits of others around them in their environment. The adolescent years present an ideal window of opportunity to educate young people on the hazards posed by high-risk behaviours like smoking and drinking, as well as to instil in them the values and habits that will assist them avoid engaging in such dangerous pursuits in the future. The first goal is to determine whether or not the students at the selected school are aware of the negative impact that smoking and alcoholism have on one's health.
