A new study published in the journal Addictive Behaviors looks at secondary effects of e-cigarettes and how they can be linked to other health issues, specifically problematic drinking.

Because past studies have linked cigarettes and drinking, the researchers wanted to see if there was a link between e-cigarettes and drinking. They studied two groups totaling 1,400 participants. They found that the participants who were e-cigarette users were more likely to drink problematically than non e-cigarette users. They also found that women were more likely to use e-cigarettes socially than men were. However, men reportedly had more risk-taking behavior.

Most of the users claimed they felt the e-cigarettes were less dangerous than regular cigarettes and therefore felt more positively about them. But studies like this one show there are a lot of negatives to this new product that is growing in popularity.
