APPLETON, WI (WTAQ) - Are you fanatic about Facebook or hooked on Twitter?
A new Midwest study says social media can be more addictive than even cigarettes.
The University of Chicago tested 250 people, and found that their fix for alcohol or nicotine is less than their need to check their friends or status online.
The survey indicated that sex and sleep are the two most longed-for events of the day -- but in the end, social media is the hardest thing to resist.
Meanwhile, teens who used to avoid Twitter are going back to tweeting, now that more of their parents and grandparents are making friends on Facebook.
Appleton North High School senior Sam Panzer tells the Post-Crescent that it's nice to have a place to go where his parents won't read what he's saying -- even though he's not really trying to hide anything sinister.
The Pew Internet and American Life Project recently found that 16 percent of young people age 12 to 17 use Twitter -- double the percentage from just two years ago.
