Mobile phones do more harm than benefit to teenagers

The most important thing of this debate to recognize the characteristics of teenagers. Teenagers are in puberty, so they are more likely to be affected by their peers. Peer pressure is a major concern to them. Teens are afraid to be teased by their schoolmates and friends. Playing games on phones is a trend among teenagers, so teens who don't play games are likely to start playing games, especially after their friends persuade them. Nearly every teenager who live in developed countries have social media accounts. They post pics and videos on their social media, and they often talk about the posts on social media when they see each other face to face. If you don't have a social media account, you are unlikely to be friend with them, because you don't even understand what they are saying. Therefore, more and more teens are turning themselves into social media like Facebook and Instagram. 

The opposition side may argue that this only make teens use their mobile phones, but not causing addiction. However, after nearly all teens are introduced to social media, they are likely to be addicted to it. Teens have poor self control. They usually care about the immediate happiness they get from playing games and texting with friends, rather than the long term problems. They can't control themselves not to use their phone that much. The opposition side may argue that teens will be addicted to something else other than their phones, if smart phones are never invented. But phones are so different to other things. Teens constantly check their phones because they are afraid that they may miss someone's message. They want to be the first one to reply so that their friends would feel happy. This makes them cannot control themselves to check them phones when they are doing homework, studying, chatting with parents or even crossing the street. Yes, drugs, alcohol do more harm than the phones, but usually only a small portion of teens are addicted to those things. Those teens who are addicted to drugs are usually teens who lack family love and perform poorly in exams, but mobile phones addicts are much more common. They are found in teens with all kinds of background, even those who have good family support are addicted to their phones. 

 

The opposition side may argue that without mobile phones, teens will be addicted to computers and that's the same. But that's not true. Computers are less addictive, because they don't have notification on whatever message you receive. You are not supposed to reply every message immediately because you can just tell your friend that you are not at home, so you can't read and reply the message. Phones are something that you take with you nearly every day. Also, many teens share their computer with their family members, so they cannot use computers at the time, but everyone has their own phone.
