research Influence of Chemical Straightening on the Stability of Drugs of Abuse in Hair
This study found that a single application of 'Lye' or 'No-Lye' chemical straighteners significantly reduced drug concentrations in hair samples from both drug-fortified standards and authentic drug users.
research Ultrastructural alterations and environmental exposure influence the opiate concentrations in hair of drug addicts
This study observed that prolonged water or soil exposure can lead to significant reductions in drug levels in bleached and natural hair samples.
research Experimental Investigations on Hair Fibers as Diffusion Bridges and Opiates as Solutes in Solution
This in vitro study found that opiate diffusion was more pronounced in damaged hair fibers than in undamaged ones, with high opiate concentrations detected in fiber centerpieces.
research Analytical chemistry studying historical pharmaceuticals and health care formulations
This review discusses the analysis of pharmaceutical relics from prehistoric times to the twentieth century and emphasizes the need for a multifaceted approach, but it presents no new experimental results.
