An interesting study out of the University of Maryland shows that when teens have a "media blackout"--meaning no access to phones, TV or Internet--they start to suffer from withdrawal symptoms.

When the researchers conducted the media blackout using 150 students for 24 hours, 79 percent of the students reported having distress, confusion and isolation. The highest reported adverse reaction to the "blackout" was the feeling of withdrawal, with 20 percent of the study's participants having that feeling. And, according to Dictionary.com, the word withdrawal means: "the act or process of ceasing to use an addictive drug."

Is technology an addictive drug? How long can you last without a cell phone, Internet, social networking site or television?
