    "Values and confidence intervals are transcribed from the latest paper's four-year table, rather than combining separate first releases.",
    "Any tobacco product includes e-cigarettes, nicotine pouches, cigarettes, cigars, smokeless tobacco, other oral nicotine products, heated tobacco, hookahs, pipe tobacco and bidis. Categories overlap.",
    "Other oral nicotine products entered the composite in 2023; its scope therefore expanded after 2022.",
    "Samples differ each year. The survey does not track individual switching or quantify nicotine dose, dependence, or harm.",
    "Cannabis vaping is outside this measure. School-based coverage excludes homeschooled and out-of-school young people.",
    "The 2025 sample included 23,630 middle and high school students, with an overall response rate of 29.7%. Collection ended six weeks early. Authors analyzed a 2024 truncation simulation to assess the potential effect.",
    "The high school four-year trends are significant for the three series shown; no 2024 to 2025 change in these high school series is statistically significant at 0.05."
