Research has shown that pregnant women perceive e-cigarettes to be a healthier option when compared with tobacco smoking.

The ECHO study will determine what the long-term health outcomes are in children born to mothers who use e-cigarettes during pregnancy. Specifically, we will focus on birth, nutritional, brain development and respiratory outcomes in children.
