Cocaine abuse can be detected by Spray Cocaine/Crack Test which is an aerosol based drug test. It is one of the most robust techniques used in the detection of drug taken/used by suspect in last two weeks. In comparison to traditional drug test methods, Spray cocaine test minimize the tendency of false negative results due to chemical decay of toxic compounds or detoxification as well reduces the chances of false positive results due to consumption of legal drug. This test is non invasive and donor friendly with a strong reliability. The Spray test use special drug wipes, which wipe or touch the suspected surface or substance at site, and then the wipe are sprayed by the aerosol based spray which resulted as the visible results of drug presence in few seconds. The most technical advantage of spray test is that it does not need any lab analysis during testing and it can be done by investigators with or without knowledge of suspect being to been tested. The main cons of spray test are that it’s comparatively costly then other methods, with risks of environmental contamination. The rate of sweat production may also affect the results adversely.
