Breath study brings roadside drug testing closer
Date:4/25/2013

micro-particles that need to be measured.

The micro-particles are able to pass through and deposit onto a filter, which can then be sealed and stored ready for analysis. Breath samples were analysed for twelve substances.

Alprazolam and benzoylecgonine were detected in exhaled breath for the first time, whereas for methadone, amphetamine, methamphetamine, cocaine, morphine, 6-acetylmorphine, tetrahydrocannabinol, buprenorphine, diazepam and oxazepam, the results confirmed previous observations.

"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," said lead author of the study Professor Olof Beck.

"In cases of suspected driving under the influence of drugs, blood samples could be taken in parallel with breath when back at a police station. Future studies should therefore test the correlation between blood concentration of drugs of abuse and the concentrations in exhaled breath."
