NARK II Duquenois-Levine Reagent (Marijuana/Hashish Hash-Oil/THC)
For Sale to Law Enforcement Only!
This presumptive test is designed to identify THC in Marijuana. Court acceptance of the Duquenois-Levine Reagent has been established through Frye Hearings and is the singularly most reliable field test manufactured. To eliminate potential false positives, always agitate the 1st ampoule sixty (60) seconds before continuing with the 2nd and 3rd ampoules. Like all our NARK II narcotic field tests, the Duquenois-Levine Reagent is meant for presumptive field drug testing. 10 tests/box.
NOTE: ALL TEST RESULTS MUST BE CONFIRMED BY AN APPROVED ANALYTICAL LABORATORY! The results of this test are merely presumptive. NARK® only tests for the possible presence of certain chemical compounds. Reactions may occur with, and such compounds can be found in, both legal and illegal products. This test must be administered following its specific instructions and may be used in conjunction with other reagents in the NARK® II Sequential Testing System.
NOTICE: NOT FOR USE WITH CBD OILS. In states where the sale of CBD (cannabinoid) oil and hemp is legal, this test should NOT BE USED as everything tested will be positive. NARK II Duquenois-Levine Reagent is a qualitative test, not quantitative. It does not distinguish between 3% or 20% THC. It only establishes that, presumptively, THC is present.
