AB  - Headspace solid-phase microextraction (HS-SPME) is assessed as an alternative to 
      liquid-liquid extraction (LLE) currently used for 
      3,4-methylenedioxymethampethamine (MDMA) profiling. Both methods were compared 
      evaluating their performance in discriminating and classifying samples. For this 
      purpose 62 different seizures were analysed using both extraction techniques 
      followed by gas chromatography-mass spectroscopy (GC-MS). A previously validated 
      method provided data for HS-SPME, whereas LLE data were collected applying a 
      harmonized methodology developed and used in the European project CHAMP. After 
      suitable pre-treatment, similarities between sample pairs were studied using the 
      Pearson correlation. Both methods enable to distinguish between samples coming 
      from the same pre-tabletting batches and samples coming from different 
      pre-tabletting batches. This finding emphasizes the use of HS-SPME as an 
      effective alternative to LLE, with additional advantages such as sample 
      preparation and a solvent-free process.
