E-cigarettes in Canada
By studying over 14,500 Canadians, Dr David Hammond at the University of Waterloo found that e-cigarette use was highest among tobacco smokers and young people. About half of youth who had tried e-cigarettes had never smoked tobacco, underlining the urgency of fully understanding the health effects of e-cigarettes as they rise in popularity.
