The abstract describes a study that investigated the use of a gas chromatographic analyser (AACTS-3000) to detect contraband substances in forensic-correctional settings. This is important because substance misuse is a major problem in these settings, and Urine Drug Screening, while effective, has limitations. For example, point-of-care urine samples may not always be possible, and patients can sometimes alter or substitute samples to avoid detection.
Over 18 months, 217 environmental samples were collected, and 66(30%) were positive for contraband substances. The most common substances detected were tetrahydrocannabinol (THC,25%), methamphetamines (19%) and cocaine (16%). Other substances detected included methylene-dioxymethamphetamine (MDMA), heroin, morphine, lysergic acid diethyl amide (LSD), tramadol, and methyl-benzoate. Fewer positive samples were detected during the period corresponding with the COVID-19 restrictions on forensic units. This suggests that the restriction may have limited the introduction of contraband into these settings. The study found that AACTS was beneficial as an ancillary tool to detect and deter contraband substances. It also provided evidence for risk management. The study emphasised the importance of adequate training for the successful implementation of the AACTS tool. The study highlights the potential of environmental sampling using gas chromatography as a valuable tool for detecting and deterring substance misuse in forensic-correctional settings. It also suggests that the COVID-19 restrictions may have had a positive impact on reducing substance use in these settings. However, further research is needed to confirm these findings and to investigate the long-term impact of the restrictions.
