Ease of access

See data table below with 95% confidence intervals.Students were asked, “How difficult or easy do you think it would be for you to get each of the following types of substances, if you wanted some?” (Figure 13.5). For e-cigarettes, the proportion of grade 7-9 students who thought that it would be “fairly easy” or “very easy” (39.0%)a was similar to the proportion who thought it would be “fairly difficult” or “very difficult” (42.6%)b.

However, perceived access varied significantly by e-cigarette use status:202 most ever-users (80.3%)c thought it would be “fairly easy” or “very easy,” compared to one-third (33.0%)d of never-users of e-cigarettes.

Perceived Risk

See data table below with 95% confidence intervals.Perceived risk was assessed by asking “How much do you think people risk harming themselves when they do each of the following activities?” for “Use an e-cigarette once in a while” and “Use an e-cigarette on a regular basis” (Figure 13.6).

Overall, the majority of students in grades 7-9 perceived “no risk” or “slight” risk of using e-cigarettes “once in a while”, but “moderate” or “great” risk of regular use.

Significantly more e-cigarette users perceived “no risk” of using e-cigarettes once in a while (46.3%)e or on a regular basis (19.0%)f, compared to never users (17.4%g and 8.7%h, respectively).203,204
