W: How many people use the Internet?
M: Close to 100 million in the United States. And that’s increasing daily by tens of thousands. E-mail and chat are by far the No. 1 and No. 2 uses. E-commerce sites come in third.
W: Are there people who are spending too much time online?
M: Based on my research, about 6 percent of people online are using the Internet compulsively. Even if we’ve overestimated, we’re talking millions. It’s not that they just stay on for two hours. I’m talking about people losing jobs, having marital problems, experiencing a very significant negative impact on their lives. The average among the most compulsive group was upward of six to nine hours online everyday.
W: Have you ever seen anything like this before?
M: This isn’t a new disease. It’s a new way of expressing the same disease: addiction. People get addicted to lots of things that are pleasurable and intense. The Internet gives you that hit, a temporary high feeling, just like exercise or drugs.
W: Can internet shopping go too far?
M: All addictions are the same, regardless of the stimulus. You shop because you get a high. The problem is: it’s so short-lived that you have to keep doing it. And that’s where it can become a compulsive pattern.
W: What should people do if they use the Internet compulsively?
M: One solution is to limit the amount of time they spend online. Have a specific task you are going to do and write that down. Put a clock next to the screen so you can keep track of time. If you can’t control your use, you might have to just log off.
