Facebook helps to quit smoking?

According to a study published in the journal 'Addiction', a Facebook-based intervention may help young adults kick the habit of smoking more effectively than other online kick-the-butt programmes. 

Significantly, this study, is the first to test the effectiveness of a smoking intervention delivered entirely on Facebook and to also use biochemically-verified abstinence from smoking.

The study was carried out by the researchers at the University of Califonia-San Franciso.
