Researchers: Social Networking Can Be More Addictive Than Nicotine, Alcohol

What about heroin?

For anyone who has quipped that they are hooked on social networks like Facebook and Twitter the latest research suggests it might be no joke.

The statistics are mind-boggling.

Those two networks alone boast well over a billion users between them. Every day, there more than half a billion 'likes' on Facebook and 350-million Twitter tweets.

It is perhaps no surprise then, that researchers from the University of Chicago found last year that social networking can be more addictive than nicotine and alcohol.
