Data Briefs | CRST CRST and CAsToR collaborated to present weighted prevalence estimates from analyses of the 2025 National Youth Tobacco Survey (NYTS), an annual cross-sectional, school-based, self-administered web-based survey designed to be representative of US middle and high school students.

So in USA in 2025, 3.8% of high school students used tobacco/nicotine products frequently (20+ days out of the last 30 days). Almost all of this was e-cigs (3.1%). Cigarettes were at 0.3% !! Nicotine pouches at 0.6%. Wow!! Lets help the 30+ million adult smokers to quit. tobaccocrst.org/data-briefs
