Your Health: 4-26-13 Breath test for drugs

A roadside breath test for drugs could be right around the corner.

New research shows a roadside breathalyzer test for marijuana, cocaine and other illegal drugs could be a step closer to reality.

Swedish scientists used a commercially available breath sampler, and were able to identify 12 substances in the breath of at least 40 patients.

The patients had taken drugs in the previous 24 hours and were recovering at a drug-addiction emergency clinic.

The study published in the latest issue of the Journal of Breath Research, is the first to detect alprazolam, the active ingredient in Xanax and other anti-anxiety drugs and benzoylecgonine, a cocaine byproduct, in exhaled breath.
