“…12 However, because it is intensely lipophilic, and significant fat stores can accumulate, urine test results for ⌬ 9 -tetrahydrocannabinol can remain positive for 4 to 6 weeks in regular users. 28 In our sample, one third of respondents thought that cannabis could be detected for 1 week or less. These physicians might falsely accuse an adolescent of continued drug use if urine testing were repeated.…”

“…Biological sample testing (particularly urine) has emerged as the most common method of drag testing in the workplace. Standards for ensuring accurate drug-use detection with sample testing have been established (3)(4)(5)(6), making this an effective procedure for drug-use evaluation. However, biological sample testing procedures have limitations which hamper their effectiveness, including problems of legality (7,8), their inability to ac-*Author to whom correspondence should be addressed.…”

The time courses of the effects of acute doses of amphetamine (5 and 10 mg/70 kg), alcohol (0.3 and 0.6 g/kg), diazepam (5 and 10 mg/70 kg), and marijuana (2.0% and 3.5% delta 9-THC) on performance engendered by each of four computerized behavioral tasks were evaluated in six human subjects. These performance-based tasks have potential commercial utility for drug-use detection in the workplace. Alcohol and marijuana effects were reliably detected for up to three hours following dose administration with most procedures. Amphetamine and diazepam effects were also detected, but the dose effects and time courses were variable. The profile of behavioral effects varied across drugs, suggesting that performance-based testing procedures might be useful in discriminating which drug was administered and the time course of the drug's effects. Results indicate that repeated measurement with performance-based drug detection procedures can provide immediate indications of performance impairment in a cost-effective and noninvasive manner and, as such, would be a useful supplement to biological sample testing for drug-use detection.

“…Recent studies have demonstrated that hair analysis is more reliable for detecting chronic cocaine use 6,7 . Urinalysis can detect the presence of cocaine for 2–3 days after last use; 8 therefore, in order to determine the validity of an individual's self‐report of cocaine usage, the interval measured must match the sensitivity of the bioassay employed.…”

Clinical Characteristics of Under‐Reporters on Urine Drug Screens in a Cocaine Treatment Study

et al. 2002

View full text Add to dashboard Cite

To explore the concordance between urine drug screen (UDS) results and self-report of cocaine use, results in a pharmacologic treatment trial for cocaine dependence were evaluated. Subjects with at least two occurrences of a positive UDS for cocaine were characterized as either an under-reporter (UR, n = 43) or a truthful reporter (TR, n = 32). Interestingly, URs attended more study sessions and were more likely to complete the study. Significant differences were found in cocaine use patterns and the prevalence of Axis I and Axis II disorders. This information may be important in guiding the judicious use of UDS in clinical and research settings.
