Young people are more responsive to seasonal promotions delivered through social media as they are more active within social media networks. There are no studies implemented with the online community to reduce the attractiveness of tobacco promotions.

Participants were categorized and added to messenger groups based on academic year and gender. Online discussions were conducted with students. They were asked to observe their Facebook walls on tobacco promotions. They were enabled to identify and prioritize determinants of tobacco promotions delivered through Facebook. Understanding on industrial influences of tobacco promotions, the attractive image created for tobacco use within Facebook and the short term, long term hams of tobacco use were improved among study participants through online discussions.

Results:
