How does the Detect Now work?
When people handle drugs, particles of drug residue remain on their fingers and the surface on which (desktop/mirror, etc.) the drugs were handled. The drug residue particles are also transferred to other objects the drug user touches, such as doorknobs, keyboards, backpacks, clothing, telephones, desktops, CDs, stereo controls, etc. The patented drug spray instantly identifies these residue particles on any surface.
