31. This graph is a rough compression of 47 haircut tests for the purposes of this judgment. It does not contain the complete sequential information that testers rely on in their interpretations.32 If the descriptions of the above results are provided, they are considered low or moderate to low.33 If the washes were analyzed, they did not find cocaine, BE or NCOC, except that the legal DNA reported cocaine containing 0.06 cm per 12 cm without identifying the sections to which it is involved.34 In interpreting these results, the trial organizations` witnesses (Ms. John, Mr. Poulton and Mr. Breidi) felt that they were isolated more due to active cocaine use than to external contamination. The exception was that Dr. Breidi did not reach this conclusion compared to the 2017 results because of their lower values – only one of the 18 sections reported cocaine above the cut-off, and this section was just above (0.52). On the other hand, Dr. Rushton was not convinced that the results were consistent with active drug use, while Dr.
McKinnon concluded that they could not be.35 The evidence in this case dealt with a number of topics, including: a. The importance, if any, of the variability of the results between the different laboratories; b. the importance and importance of sector guidelines on thresholds and hair strand testing in general; c. The importance of the results of cocaine or its metabolites below the cut-off values.d. The process of “washing” the hair and the importance of comparison between wash samples and test samples. (a) Between July 2015 and December 2016, even when she was pregnant, the mother had used cocaine, although rarely and/or at a low level; B. The mother had not told the truth about her drug use at the time. The US SAMHSA [Substance Abuse and Mental Health Services Administration] and the European Workplace Drug Testing Society (EWDTS) require the discovery of cocaine and two other metabolites, respectively above the cut-off level, before the test can be considered positive. After hearing detailed evidence from the various experts, the court found that, contrary to my denials, there had been a low consumption of cocaine after July 2015, until December 2016. The LA was unable to prove her case that she had used cocaine after December 2016. If a person stops taking a medication, it is always possible that low levels of medication are proven in a hair sample. This is due to the fact that at some point about 15% of the hair does not grow actively.
These hairs contain drugs that would have ended up in the hair during drug use (Tsanaclis, 2007). Blue, I can`t provide legal advice on this blog. I can`t give toxicological advice either. What I can say is that the drugs often stay in the hair after stopping use, usually at a lower residual level for several months – but if someone honestly states that he stopped at some point, we would expect the results of the hair strand to show a drop, then clear tests, perhaps a few months after the shutdown.
