†"Asian" combines students who identified as West Asian/Arab, South Asian or East/Southeast Asian.
‡The 2014/15 Canadian Student Tobacco, Alcohol and Drugs Survey does not include a generalizable sample of students from the province of New Brunswick. As a result, data for New Brunswick students cannot be used to produce provincial estimates.
§Students who reported using little cigars or cigarillos, cigars, roll-your-own cigarettes, bidis, smokeless tobacco, water pipe or blunt wraps.
¶Data suppressed because of unacceptable data quality (due to high variability or low numbers).
**Because of moderate sampling variability, these data should be interpreted with caution.
