Marijuana Field Test Kits
The Duquenois-Levine field test cannot distinguish marijuana from industrial hemp. For any offense occurring on or after March 21, 2019, that involves 1) plant material packaged and labelled as a “hemp product;” or 2) a defendant that has raised the industrial hemp affirmative defense pursuant to Virginia Code § 3.2-4113, the evidence should be submitted to the laboratory. If the affirmative defense has been raised, please note it on the Request for Laboratory Examination (RFLE) so that a quantitative analysis can be performed (once the method is available).
The Duquenois-Levine field test kits for detection of Marijuana under § 19.2-188.1(B) that have been evaluated and approved by the Department of Forensic Science are accessible in the links below.
