Testing for drugs of abuse in oral fluids can strongly benefit the criminal justice field as a less invasive and cost-effective approach for drug detection when compared to blood or urine sampling. Oral fluid analysis has facilitated laboratory analysis for many drugs of abuse and is a constantly evolving analysis procedure which benefits from increasingly sensitive methods of detection. The Laser Diode Thermal Desorption (LDTD) source combined with Mass spectrometry is presented as a new screening tool for drug analysis in Oral Fluids. Analysis speed of LDTD provides accurate results in seconds in combination with exceptional specificity of MS instruments make a powerful platform for the screening of different drugs of abuse and new emerging drugs. Different extraction procedures are available; however those methods depend on specific drug conditions: basic or acid drugs / hydrophilic or hydrophobic. A new extraction approach, Supported Liquid Extraction (SLE+) is evaluated as generic extraction procedure.
