ABSTRACT We examined the utility of drugs versus urine to detect drugs of abuse by characterizing the number of hair and urine samples provided and the agreement between hair, urine, and self-reported drug use. Of 40 participants, 39 (97.5%) provided urine, whole only 31 (77.5%) agreed to provide hair (3 (7.5%) declined, 6 (15%) were not able). Hair detected more drug use than urine and self-report, and concordance between urine and self-report was 90% or greater. The advantage of hair to detect drug use, particularly cocaine, may warrant inclusion of hair samples to document cocaine or drug use during longer retrospective periods; if documenting recent use of drugs other than cocaine, self-report may suffice.

头发、尿液和自我报告在包括精神分裂症患者在内的研究中监测药物使用的效用

摘要 我们通过表征提供的头发和尿液样本的数量以及头发、尿液和自我报告的药物使用之间的一致性，检查了药物与尿液在检测滥用药物方面的效用。在 40 名参与者中，39 名 (97.5%) 提供了尿液，只有 31 名 (77.5%) 同意提供头发（3 名（7.5%）拒绝，6 名（15%）不能提供）。头发检测到的药物使用多于尿液和自我报告，尿液和自我报告之间的一致性为 90% 或更高。头发检测吸毒，特别是可卡因的优势，可能需要包括头发样本，以记录更长的回顾期内的可卡因或吸毒情况；如果记录最近使用可卡因以外的药物，自我报告可能就足够了。
