The scene of the illegal drug trade has been changing constantly, especially amid the current opioid emergency. Now, a team of researchers has invented a promising new tool that can recognize smaller concentrations of drug powders than almost any other field-testing equipment. The newly developed MagLev device contains two brick-like magnets above and below a retractable, clear vessel and could help law enforcement in the field to combat the opioid crisis. Researchers believe the promising new tool could help law enforcement identify the composition of the seized material and save lives.
