The Prevalence of Methamphetamine and other Drug Use during Pregnancy in Hawaii

Methamphetamine abuse is epidemic in Hawaii, but the extent of use among pregnant women is unknown. We sought to define the prevalence of use during pregnancy. We conducted a cross-sectional study of consecutive births between November and December 1999, and determined that the prevalence of drug metabolites in meconium were fatty acid ethyl esters: 72 (17.1%); cotinine: 33 (7.7%); opiates: 4 (0.9%); delta-9 tetrahydrocannabinal: 1 (0.2%); and methamphetamine: 3 (0.7%). Including three positives discovered solely through forensic testing, the overall prevalence of methamphetamine exposure during pregnancy was 1.4% (6/443). The prevalence of methamphetamine was low compared to the prevalence of fatty acid ethyl esters, reportedly indicative of ethanol exposure, and cotinine, a tobacco metabolite. In Hawaii, more attention should be directed towards alcohol and tobacco use during pregnancy.
