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).
