The fatty acid ethyl esters (FAEEs) hair test, a biomarker of excessive  alcohol exposure, has demonstrated its potential for use in fetal alcohol  spectrum disorder (FASD) diagnosis. FASD may be compounded by polydrug exposure. 
Our objective was to determine the likelihood of positive FAEE test among  parents testing positive for other drugs of abuse. 
Samples submitted for FAEE  hair analysis by Children's Aid Societies between October 2005 and May 2007,  also concurrently tested for cocaine, cannabinoids, opiates, methamphetamine,  amphetamine, benzodiazepines, methadone, and/or oxycodone, were included in our  analysis. Subjects consisted of parents suspected of using excessive amounts of  alcohol. 
Parents testing positive for drugs of abuse had a significantly  increased risk for testing positive for high FAEE. 
Mothers testing positive for  heavy chronic alcohol use were found to have a threefold increased risk of  testing positive for cocaine (odds ratio = 3.26, 1.1–9.7). 
Our results suggest  that parents abusing stimulants are at risk of high alcohol exposure, which put  their unborn children at risk for FASD.
