As children move from adolescence to young adulthood, they encounter dramatic physical, emotional, and lifestyle changes. Developmental transitions, such as puberty and increasing independence, have been associated with alcohol use. So in a sense, just being an adolescent may be a key risk factor not only for starting to drink but also for drinking dangerously (Alcohol Alert, 2006).
Adolescent period is supposed to be the most dangerous period of human life. The making or breaking of a person normally happens during this period. Because of the influence of developmental transitions, a lot of physical and cognitive changes occur during this period. Teenagers will exhibit a sense of urgency to free from all the tie-ups during this period. They want to enjoy life and there are chances of breaking the restrictions enforced upon them during this period. Drinking is normally prohibited for them and they may feel that it is an injustice. It is quite possible that under the influence of either friends or other antisocial elements they may start drinking during this period. They wanted to prove a point in front of others that they also became adults and have the capacity to enjoy a drink.
Heredity, environment and personality disorders may also serve as reasons for underage drinking. Children of alcohol addicted parents may have increased a tendency to start drinking at an early age. Same way, children living in an environment suitable to drinking may also develop drinking habits.
