Levels of nicotine in dust from homes of smokeless tobacco users.

ABSTRACT:

Background

Smokeless tobacco products, such as chewing tobacco or moist snuff, contain many of the same constituents as tobacco smoke and are also known to cause cancer; however, little attention has been paid to indirect exposure of children to tobacco constituents via parental smokeless tobacco use.

Results

Median nicotine concentrations for residences with smokeless tobacco users were signifi
