The aim of the present study is to present information concerning Workplace Drug Testing in Northern Greece for the period of 2000-2006, which is in continuation of previous testing. Cases included: professional drivers, individuals at pre-employment stage for security services, prostitute houses and housekeepers at prostitute houses. During the period 2000 - 2006, we handled a total of 2665 cases, each of which was examined for the presence of 5 groups of controlled substances (cannabinoids, opiates, benzodiazepines, cocaine and amphetamines). Screening was performed with Enzyme Multiplied Immunoassay Technique (EMIT), while verification of positive results and identification of substances present was achieved through chromatographic techniques.Of the 2665 cases handled in this period of 7 years, 67% concerned candidates for employment at security services, 18% concerned professional drivers, 13% concerned individuals pursuing employment at prostitute houses and 2% concerned individuals pursuing employment as housekeepers at prostitute houses.Of the total 2665 samples tested, 105 samples were positive, corresponding to 4% of the total cases. Of the controlled substances abused, cannabinoids seem to be the most popular abused drug representing 72.81% of the positive samples. Opiate abuse corresponds to 16.27% of the positive samples, cocaine abuse corresponds to 5.19% of the positive samples and benzodiazepine abuse corresponds to 5.73% of the positive samples.
