AB  - Trace amounts of street samples of cocaine hydrochloride and 
      N-methyl-3,4-methylenedioxy-amphetamine (MDMA) on natural and synthetic textiles 
      were successfully detected in situ using confocal Raman microscopy. The presence 
      of some excipient bands in the spectra of the drugs did not prevent the 
      unambiguous identification of the drugs. Raman spectra of the drugs were readily 
      obtained without significant interference from the fibre substrates. Interfering 
      bands arising from the fibre natural or synthetic polymer structure and/or dye 
      molecules did not overlap with the characteristic Raman bands of the drugs. If 
      needed, interfering bands could be successfully removed by spectral subtraction. 
      Also, Raman spectra could be acquired from drug particles trapped between the 
      fibres of highly fluorescent textile specimens. The total acquisition time of the 
      spectra of the drug particles was 90 s accomplished non-destructively and without 
      detachment from their substrates. Sample preparation was not required and spectra 
      of the drugs could be obtained non-invasively preserving the integrity of the 
      evidential material for further analysis.
