DPS Crime Lab Marijuana Testing Policy & Procedure
March 16 - December 31
With the passage of House Bill 1325, establishing whether or not a piece of evidence is marijuana in the courtroom has become a burdensome task. In response to the change in marijuana’s statutory definition, the Texas Department of Public Safety Crime Lab has developed a procedure that will allow their analysts to determine if a substance is, or is not, marijuana. In this free half hour training, TDCAA’s Clay Abbott will interview DPS scientists Chance Cline and Jennifer Hatch regarding the manner and means of this forensic testing.
