Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the study is to quantify the efficacy of hand washing (HW) and ethyl alcohol-based hand sanitizer (S) for third-hand smoke (THS) removal in a sub-sample of non-staff smokers using nicotine wipes on adjacent fingers before and after HW/S. The hypotheses are that detectable levels of surface nicotine will remain on participants' fingers, regardless of hand washing (HW) and ethyl alcohol-based hand sanitizer (S) attempts and that greater finger levels of surface nicotine will remain after alcohol sanitization compared to hand washing.
