Peer pressure
Peer pressure is influenced by the peer group members. It often happens to children during puberty. The group defines some social values. For somebody to stay "cool" in that group, they must act like other people. Social pressure (and wanting to be accepted or in favor inside the group) leads people to do things they would not do otherwise. For example, it can influence a person to smoke cigarettes or  marijuana, to drink alcohol, commit crimes, and many other things that they might regret.Most of the time,adolescents create a peer group of their age to enjoy themselves. They have strong faith and belief in their friends of the same group. The new desires, aspirations, and interests are developed because of the changes they experience. They become sensitive and sentimental.
