It is reasonable to say that every teenager can be affected by peer pressure (从众心理) at some point. Every day, in any high school, peer pressure has a major influence over the behavior of teenagers. It can be as subtle (微妙的) as being persuaded to be late for class or as extreme as a dangerous drug. Whether subtle or extreme, peer pressure can have damaging, sometimes life changing, and even serious results.

“Teens don’t often consider the long-term results that some behavior can cause,” said Terri Price, a researcher. “Peer pressure can be very difficult to handle for many teens because of their fears of not fitting in”. Peer pressure has always been part of teen life, but teens experience it differently than their former generations did in the past. Sources of peer pressure have increased because of the Internet and other electronic communications.

Recognizing peer pressure can be as simple as noticing that you have been asked to do something that you are not comfortable with. “Listen to your instinct （直觉） , which is a sign for whether something is right or wrong. If it feels wrong, then most likely it is. ”says Price.

Teens are in a time of life when they are still discovering who they are. Many teens are influenced by peer pressure because of their insecurities (不安全感). This can make them helpless especially when their self-control is weak or they lack healthy support, causing them to take risky behavior or turn to unhealthy support.

Dealing with peer pressure is a topic of concern for teens. People can say, “Just say no,” but the truth is that the statement is easier said than done.
