Study Summary
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.
Primary Outcome
Nicotine will be sampled from one finger of each participant's dominant hand (thumb, index, or middle finger). Finger will be wiped and nicotine level will be quantified.
Interventions
- DRUG 2% Chlorohexidine Gluconate soap
- DRUG 62% ethyl alcohol-based hand sanitizer
