Methods Urine and meconium samples were collected from 56 infants born to mothers prescribed methadone during pregnancy and a confidential interview conducted soon after delivery. Samples were screened for drugs of misuse and meconium samples analysed for the presence of fatty acid ethyl esters (FAEEs) to detect prenatal alcohol exposure. Results 91% of infants had been exposed to illicit drugs in utero, including opiates (73%), benzodiazepines (70%) and cannabinoids (59%). 47% of infants had elevated FAEEs. Meconium was more sensitive at detecting in utero drug exposure than urine toxicology (p<0.01 for opiates, benzodiazepines, cannabinoids) or maternal interview (p=0.03 for opiates, p<0.01 for cannabinoids). Conclusions The majority of infants born to mothers prescribed methadone during pregnancy are exposed to polysubstance misuse, and almost one-half additionally exposed to excess alcohol.
