Under the Regulations for the Approval of Marijuana Field Tests for Detection of Marijuana Plant Material (6VAC40-50), the Department of Forensic Science has rescinded the approval of all Duquenois-Levine field tests for use during trial.  All manufacturers have been notified of this action by the Department.  Law enforcement agencies will have/have been notified that the previously-approved Duquenois-Levine field tests should no longer be utilized for purposes of trial testimony under Virginia Code § 19.2-188.1(B) as to whether or not any plant material is marijuana.  Currently, there are no marijuana field tests approved by the Department for use at trial under 6VAC40-50 and Virginia Code § 19.2-188.1(B).

This action does not affect the approval by the Department of any Duquenois-Levine field tests for use during preliminary hearing under the Regulations for Approval of Field Tests for the Detection of Drugs (6VAC40-30) and Virginia Code  § 19.2-188.1(A).  A list of approved field tests under 6VAC40-30 can be found in Volume 32, Issue 8, on pages 1507 through 1514 of the Virginia Register issued on December 14, 2015.
