NARK II Presumptive Narcotics Test Pouches

Sirchie's NARK® drug identification pouches can presumptively identify several families of substances that could be abused drugs. Each of the tests is comprised of one or more chemical reagents. When a color or series of colors occurs within a specific testing sequence, a positive identification may be presumed. 

The results of NARK® test pouches are 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.

Presumptive identification is generally recognized within our legal system as a component of probable cause. There is no drug identification system presently in use which completely eliminates the occurrence of false positives and false negatives. A forensic laboratory is required to qualitatively and quantitatively identify an unknown substance.
