A third (n = 312 33.4%) provided a hair sample. Hair donation response rates and reasons for refusal were examined from this cross-sectional study. We surveyed 933 adults entering EDM parties in New York City in 2017. We examined willingness to donate a hair sample to be tested among those surveyed in a population at high risk for consuming adulterated drugs-electronic dance music (EDM) party attendees. Biological testing can complement survey research, and hair-testing is an appealing method as many drugs are detectable for months post-use. Non-disclosure of drug use on surveys is common and many drug users unknowingly ingest adulterant or replacement drugs, which leads to underreporting of use of these drugs. Palamar, Joseph J Salomone, Alberto Cleland, Charles M Sherman, Scott Willingness to Provide a Hair Sample for Drug Testing among Electronic Dance Music Party Attendees. A unique finding of this research is that certain ethnic hair products can replace moisture as a diffusion medium, thereby increasing the susceptibility to contamination over 100-fold compared to petroleum-based products. Some products increased the methamphetamine and cocaine concentrations in all hair types. Three different chemical classes of ethnic hair products were applied to Caucasian, Asian, and African hair. This research studied susceptibility of head hair to external cocaine and methamphetamine when hair products have been applied.
The question of why different races appear more susceptible to hair contamination by external drugs remains controversial.
Kidwell, David A Smith, Frederick P Shepherd, Arica R Hair analyses were negative for methylphenidate and its metabolite (ritalinic acid). Biological matrices testing for psychoactive drugs disclosed both acute and chronic intoxication with quetiapine and sertraline administered by the mother.Įthnic hair care products may increase false positives in hair drug testing. Quetiapine was found in the first four segments with a mean concentration of 1.00 ng/mg ± 0.94 ng/mg hair while sertraline and its metabolite, desmethyl-sertraline, were found in all segments with a mean concentration of 2.65 ± 0.94 ng/mg and 1.50 ± 0.94 ng/mg hair, respectively. The suspicion that the mother administered drugs chronically prompted the analysis of six, consecutive 2-cm segments of the child's hair, using ultra-high performance liquid chromatography-tandem mass spectrometry, thereby accounting for ingestion over the previous 12 months. This study presents the case of a 4-year-old healthy child admitted to the paediatric ward for suspected accidental intoxication due to ingestion of narcoleptic drugs (methylphenidate, sertraline and quetiapine), taken on a regular basis by his 8-year-old brother affected by Asperger syndrome.Intoxication can be objectively assessed by measurements of drugs and metabolites in biological matrices with short-term (blood and urine) or long-term ( hair) detection windows. At the hospital, the child's blood and urine were analysed by immunoassay (confirmed by liquid chromatography-mass spectrometry), and sertraline and quetiapine and their metabolites were identified.

This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. A short questionnaire was circulated amongst the membership and interested parties.
Current status of accreditation for drug testing in hair.Ĭooper, Gail Moeller, Manfred Kronstrand, RobertĪt the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair.
