Endotoxin and [Formula: see text] Contamination in Electronic Cigarette Products Sold in the United States.

ABSTRACT:

Background

Cigarette smoke contains microbes and microbial toxins, such as endotoxin and [Formula: see text], that may have adverse respiratory effects. To our knowledge, the potential for contamination of electronic cigarette (EC) products sold in the United States has not been investigated.
