Abbreviation: e-cigarettes = electronic cigarettes.
* Frequency of current use of e-cigarettes; cigarettes; cigars (cigars, cigarillos, or little cigars); chewing tobacco, snuff, or dip; snus; dissolvable tobacco products; pipe tobacco; hookahs; heated tobacco products; and nicotine pouches was determined by asking respondents on how many days they smoked or used each respective tobacco product during the past 30 days. Respondents could enter a valid response of 0–30 days. Responses were recoded as 1–5 days, 6–19 days, and 20–30 days.
† Estimates of frequency of use of dissolvable tobacco products are statistically unreliable (overall and by school level) and are omitted from the table.
§ Estimated weighted total number of users was rounded down to the nearest 10,000 persons. Overall estimates might not directly total to sums of corresponding subgroup estimates because of rounding or inclusion of students who did not self-report grade level.
¶ Data were statistically unreliable because of unweighted denominator <50 or a relative standard error >30%.
