Background. We do not know of studies in our city that indicate the degree of poly illicit drugs consumption in motor vehicles drivers. Use of illicit drugs can explain in some cases the lack of agreement among measurement of breath alcohol test, blood alcohol concentration, and clinical examination in motor vehicles drivers when they are suspects of alcoholic intoxication. In this report we want to center on showing the use of illicit drugs and their clinical manifestations in a sample of motor vehicles drivers. Objective. To determine the consumption of illicit drugs in a sample of motor vehicle drivers, when they are suspects of alcoholic intoxication. Materials and methods. We took a representative sample within 68 motor vehicle drivers. We performed on all of them clinical examination, measurement of breath alcohol tests and blood alcohol concentration. Also we collected urine samples. Five (5) substances were investigated according to their high prevalence in our population: opiate, marijuana, cocaine, amphetamines and benzodiazepines. Results.There were seven cases of illicit drug consumption: the most frequent combination found was (5-7 cases) alcohol plus marijuana. In three cases we found consumption of three illicit drugs: 2 cases have alcohol, marijuana and cocaine. Only one case of alcohol, benzodiazepine and cocaine. Conclusions. In the sample analyzed the use of illicit drugs was 10.14 %. The most common form of use is a depressor with a stimulant. If it is recent, it diminishes the neurological manifestations, but it does not affect the presentation nor the severity of the rotacional nystagmus. The alterations of the superior mental functions were seen to be associated with alcohol consumption plus benzodiazepines. Combination of two depressors increases the motor alterations and seems that it alters the superior mental functions. In the negative clinical examinations it was concluded that there was no alcohol intoxication and no use of other psychoactive substances.
