•Analysis of various alcoholic and non-alcoholic beverages.•The importance of the safety of drinks in for their consumers.•The innovative methods of DBS used to analysis.•Danger Date-rape Drugs (DRD) substances.•The concept of White Analytical Chemistry (WAC). A new methodology for the detection of ketamine, flunitrazepam, and diazepam in beverage samples by the dried sample spot method was developed. The method is characterized by very low LODs in all tested types of beverages (100 ng/mL for ketamine, 25 ng/mL for flunitrazepam and diazepam) and great precision at the concentration of 100 ng/mL for all analytes. The significant advantages of this method are the consumption of fewer amount of samples and the possibility of securing the beverage samples on DBS cards at room temperature. The proposed method was evaluated by the innovative WAC approach according to Green Analytical Chemistry. The results of the evaluation indicate the best results of this method in terms of analytical quality compared to the other methods from the literature, however other aspects such as green chemistry and economical are also good. The DBS/MAE/LC-MS method could be used for qualitative analysis for drugs detection in cases of date-rape drugs analysis. Display omitted
