Frequently Asked Questions
How do First Defense wipes work?
What drugs does the First Defense wipe detect?
First Defense wipes are primarily focused on fentanyl and their derivatives.
How does the wipe actually work?
When the primary ingredient in the First Defense wipe comes in contact with fentanyl, it instantly changes color to indicate the presense of fentanyl.
First Defense wipes are a presumptive test. What is a presumptive test?
A presumptive test refers to tests or procedures that indicate the possible presence of a substance but does not confirm its actual identity. Presumptive tests are typically used as preliminary screenings to suggest further testing is needed.
Is it possible to detect a false negative?
Yes, fentanyl can be present in various forms such as powder, pills, liquids, solids in very minute quantities.
Fentanyl may be mixed or combined with other compounds, so the wipe may not detect low levels of fentanyl.
A negative/no result on the test cannot guarantee that a harmful drug like fentanyl or other harmful opioids are not present, in another part of the sample or at an undetectable level, and at no time can/should this information be used to assert that a substance is safe.
Users should continue to take safety precautions designed to prevent exposure to dangerous substances during the handling, testing, and/or transporting of suspected controlled substances.

No, most are found in cosmetic products.
