what test does the georgia bureau of investigation do for marijuana
In 2009, the Georgia Bureau of Investigation trained more than 1,600 police officers in the use of the D-L test, resulting in a 98 percent reduction in the use of marijuana lab tests.everal studies claim, falsely, to have validated the specificity of the D-L test. For instance, a seemingly authoritative 2000 study funded by the National Institute of Standards and Technology (NIST) purported to have validated the capacity of the D-L test to specifically and definitively identify marijuana.
