Electronic cigarettes, commonly referred to as "e-cigs" appeared on the market in 2004. In recent years the devices have skyrocketed in popularity. Over the past decade e-cigarettes have launched a $2 billion dollar industry. E-cigs allow smokers to benefit from the effects of nicotine without consuming the carcinogenic ingredients of traditional tobacco products. The products have also been credited as a means of weaning the body from nicotine addiction.

Lead researcher Rachel Grana told Reuters that the correlation between e-cigarette use and smoking cessation is nonexistent. "We did not find a relationship between using an e-cigarette and reducing cigarette consumption," she said.

Grana and other researchers involved in the study noted that e-cigs are positioned incorrectly in the tobacco market. "E-cigarettes are frequently marketed and perceived as cessation aids," Grana's research team said in an e-mailed statement.
