Study: Some texting teens share traits with compulsive gamblers
One could make the argument that there is also a similarity between drug addiction and text addiction. Withholding both could cause withdrawals (more mental than physical for texters), and those who are addicted will read and write texts in situations where doing so endangers their lives, like while they are behind the wheel of a car. That is the perfect definition of an addict. These teens are holding on to the steering wheel with one hand, while trying to type with the other. And instead of keeping their eyes on the road, they are looking at the screen on their phone. Addiction is often defined as the act of continually doing something even if you know it will harm you.
While it might be too early to obtain enough data, what would be interesting would be to see how many of the compulsive teen texters go on to have other disorders as an adult.
