|For a short time in October 1996, cocaine adulterated with atropine (mean content 7%) appeared on the illicit drug market in Zurich. Subsequently, four cases of suspected driving under the influence of drugs proved to be related to atropine, as was shown by our investigations. Two of these cases will be presented in detail.
In both cases the medical examination revealed mydriasis, slurred speech, bloodshot conjunctivas, in case 1 furthermore disorientation, in case 2 agitation.
Atropine was detected in toxic concentrations in whole blood (0.003 and 0.009 mg/L, respectively) and urine (6.6 and 27.0 mg/L, respectively) taken from the drivers a few hours after the event. Identification was carried out by GC/MS, quantitation by GC using nitrogen-phosphorus-detection. The intake of cocaine was proven in both cases. Additionally, in case 2, 0.020 mg/L of free morphine were detected in blood by GC/MS.
