    Abstract: The present invention is a testing apparatus and method for detecting the presence of a date rape drug such as flunitrazepam or gamma hydroxyl butyrate in a liquid, such as an alcoholic beverage. The testing apparatus includes a base member and a flap member removably attached to the base member. The testing apparatus also includes at least one testing stick enclosed within the base member. The testing sticks include an elongated member and a chemical reagent disposed on the distal end or anywhere along the elongated member. The chemical reagents utilized to detect the presence of flunitrazepam are Zimmerman's Test reagent methanolic 2,4-dinitrobenzene and potassium hydroxide and the chemical reagent for GHB is 5,5 Dibromo-o-cresolsulfonphthalein. The chemical agent reacts with the date rape drug to produce a change in color of the chemical reagent indicating the presence of the date rape drug in the liquid.
