Imagine if this Swedish invention were to become a part of stop-and-frisk. US News and World Report writes:
Police might soon be able to detect more than just alcohol on their breathing test devices. A new Swedish-designed device can detect 12 different controlled substances, including methamphetamine, cocaine, heroin, morphine and marijuana.
In a study published in the Journal of Breath Research Thursday, Olof Beck, of Sweden’s Karolinska Institutet, detected drugs on the breath of 47 patients at a drug addiction emergency clinic.
“Considering the samples were taken 24 hours after the intake of drugs, we were surprised to find that there was still high detectability for most drugs,” Beck said in a statement. He suggested that a breath test could be given at the scene and then confirmed with a blood test later.
