The drug detection device which is composed of a pair of members interconnected together to form an internal enclosed chamber. An elongated swab having an absorbent tip is located within the internal enclosed chamber. One of the members of the housing has attached a pair of separate compartments which are interconnected by a frangible seal and further being interconnected to the internal chamber by a frangible seal. Within each of these compartments there is to be located a different substance and upon breaking of the frangible seal between the compartments, the substances within these compartments are to be intermixed. Upon the breaking of the frangible seal to the internal chamber, the tip of the swab will then become in contact with the intermixed substances. The other member of the housing has attached at its closed end a third compartment and within this third compartment is to be located a third substance. After the tip of the swab has been placed in contact with the drug contact area and caused to come in contact with the first two substances, the tip of the swab is then placed adjacent the third compartment and upon breaking of its frangible seal, the tip of the swab will then be contacted by the third substance. If the tip of the swab was placed in contact with a certain family of drugs, the tip of the swab will then change color. Prior to use of the device of this invention, the pair of members of the device are sealingly closed so as to maintain the device in an uncontaminated condition prior to use. |
