Between 2014-15 and 2016-17, estimates for ever use of e-cigarettes increased in some provinces, while remaining similar or even decreasing slightly in others (Table 13.1). Estimates for past 30-day use appear to have increased in all provinces, although to varying degrees. Increases in prevalence estimates between survey waves were particularly large in Nova Scotia.
