Statewide Prevelence of Illicit Drug Use by Pregnant Women--Rhode Island

Erratum: Vol. 39, No. 14

In "Statewide Prevalence of Illicit Drug Use by Pregnant Women--Rhode Island," the toxicology screen cutoff measurements were incorrectly listed in the third paragraph of the article (page 225). The second and third sentences of that paragraph should read: Toxicology screen cutoffs were: cocaine, 300 ng/mL; amphetamines, 1000 ng/mL; opiates, 300 ng/mL; and cannabinoids, 100 ng/mL.* Positive results were confirmed with thin-layer chromatography for cocaine (150 ng/mL), opiates (300 ng/mL), and cannabinoids (50 ng/mL); gas chromatography was used to confirm positive results for amphetamines (300 ng/mL).
