Percentages are weighted; frequencies are not weighted. Confidence intervals are calculated using the delta method. * Statistically significant differences were detected in examining tobacco use status by sex, age, education, and past 30-day MJ use (Pearson X² test, p < 0.05). SHS exposure and creatinine level significantly varied based on tobacco user status (one-way ANOVA, p < 0.05). ^ Estimate should be interpreted with caution because it has low precision. It is based on a denominator sample size of less than 50, or the coefficient of variation of the estimate is larger than 30%. Data excluded if creatinine level ≤ 10 or ≥ 370 mg/dL.
