TUESDAY, April 22, 2025 (HealthDay News) — Both dual use of traditional and electronic cigarettes and exclusive cigarette use are associated with higher toxicant exposure than exclusive e-cigarette use, according to a study published online April 15 in Nicotine & Tobacco Research<\/em>.<\/p>\n Zheng Xue, M.S.P.H., from the American Cancer Society in Atlanta, and colleagues analyzed data from 2,679 adult participants in wave 5 of the Population Assessment on Tobacco and Health Study to better understand the health impact of dual use.<\/p>\n The researchers found that the dual-use groups with high numbers of cigarettes per day had higher levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and volatile organic compounds versus those with low numbers of cigarettes per day (e.g., NNAL for high cigarettes per day\/high e-cigarette: 257.07 ng\/mg creatinine versus low cigarette\/high e-cigarette: 64.57 ng\/mg creatinine; high cigarette\/low e-cigarette: 312.02 ng\/mg creatinine versus low cigarette\/low e-cigarette: 144.11 ng\/mg creatinine). Compared with exclusive e-cigarette use, cigarette use (dual or exclusive use) was generally associated with higher biomarkers of exposure, though metal exposure was similar between the groups.<\/p>\n “Clinicians and public health practitioners should increase awareness that dual use of cigarettes and e-cigarettes is not safe and may present similar risks as continuing to smoke cigarettes, especially if one does not reduce the number of cigarettes smoked,” Xue said in a statement.<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n
