An adsorption material for adsorbing saliva samples is fixed on the sampling part, and an alcohol detection test strip is arranged on the detection part. The drug detection in the saliva sample is carried out by using the colloidal gold competitive inhibition method immunochromatography technology. The drug detection card includes a sample pad, a colloidal gold combination pad, a nitrocellulose membrane fixed with a drug antigen to be tested, and an absorption pad. A plurality of detection lines and at least one quality control line are arranged on the nitrocellulose membrane fixed with the drug antigen to be tested. The sample pad, the colloidal gold combination pad, the nitrocellulose membrane fixed with the drug antigen to be tested, and the absorption pad are sequentially pasted on a plastic lining board. The colloidal gold combination pad is fixed with a specific antibody against the drug to be tested, and the quality control line is fixed with a sheep anti-mouse polyclonal antibody.
