Figure 2. — Adjusted geometric mean concentrations representing exposure to (A) fluorene, (B) pyrene, (C) acrylonitrile, (D) acrylamide, (E) nicotine, and (F) tobacco-specific nitrosamine NNK among single tobacco product users, stratified by self-reported past 30-day use of cannabis (n = 3331). All estimates are weighted and adjusted for urinary creatinine, age, sex, race, education, secondhand smoke exposure, cannabis use, frequency and recency of product use. Toxicant biomarker analyses adjusted for logged nicotine intake (TNE-2). Bold and starred values indicate statistically significant differences between non-cannabis users and past 30-day cannabis users (p < .05).
