Abstract: Two in-field campaigns were performed in 2009 to elucidate the contents of illicit psychotropic substances in airborne particulates of Italian cities. Twenty-eight localities of eight Italian regions were investigated in winter, and further eleven sites in June (14 regions in total), thanks to contribution of Regional Environmental Agencies. Cocaine was found almost everywhere, although some sites were rural or suburban. The maximum was recorded in Milan in winter (w0.39 ng m3), and "high" values (up to w0.16 ng m3) in other Northern cities and in Rome. Besides cocaine, three cannabinoids will be monitored, namely D9-tetrahydrocannabinol, cannabidiol and cannabinol. The three compounds often affected the air at lower extents than cocaine, and sometimes resulted absent. Cannabinol accounted for up to 90% of the total. The concentrations of illicit compounds were up to six times lower in June than in winter. This decrease was probably induced by the lowering of boundary layer height typical of winter, and by the oxidizing capacity of atmosphere, which is stronger in the warm season. Compared to n-alkanes, polynuclear aromatic compounds, nicotine, caffeine and airborne particulate, cocaine seemed to follow a peculiar behaviour; in fact, meaningful (0.80) Pearson (linear) regression coefficients were calculated from the corresponding concentrations only at local scale (e.g. Rome), and within just one season. Improvements of the method are needed to monitor illicit drug metabolites (e.g. benzoylecgonine, ecgonine methyl ester, 9-carboxy-11-nor-D9-tetrahydrocannabinol), heroin and semi-volatile amphetamines.
