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.

Nicotine level on finger #1
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.
Time frame: baseline
Nicotine level on finger #2
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.
Time frame: 5 minutes after hand washing or sanitizing
Nicotine level on finger #3
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.
Time frame: 1 hour after hand washing or sanitizing
