RESUMO

The consequences of car accidents in the traffic when psychoactive drugs are abused by professional drivers are of great concern of specialists in the subject as well as of the general population. For the Brazilian Traffic Code of 1997 to drive under the influence of alcohol, with blood leveI superior to six decigrams per liter, or any other psychoactive drug which causes physical or psychic dependence is considered an infraction in which the transgressor is subject to heavy penalties. The objective of this work was to investigate the possibilities of using saliva as biological samples to screen the use of alcohol and drugs (amphetamine, methamphetamine, cocaine and marijuana) by traffic drivers. In order to achieve this aim, a method was developed and validated for the serial determination of those analites in a single aliquot of a saliva sample. Gas-chromatographic/ headspace for the determination of alcohol and solid phase microextraction (SPME) for the determination of the other drugs were used in the analyses. Samples collected at random from truck drivers (n=561) in public roads in the city of São Paulo were analyzed by the proposed method. The obtained results were: 17 (3.0%) of all analyzed saliva samples were found to be positive, being 8 for ethanol, 4 for amphetamine, 2 for cocaine, 2 for tetrahydrocannabinol (THC) and 1 for cocaine and THC simultaneously. This study pioneered in Brazil the use of saliva as a very convenient biological sample to screen individuaIs driving under the influence of drugs
