Mistral Security’s aerosol presumptive drug tests are available in three different sizes, allowing for 10, 50, or 100 sprays. These kits are inexpensive, easy to use, and easy to handle. You can mix and match any test you might need. The Detect 4 Drugs (D4D) general screening aerosol testing kit detects marijuana, heroin, amphetamine, methamphetamine, and 10 other drugs. It can be used for bulk drug detection and identification or to detect trace drug residue, and it will not destroy evidence.
