Drug Analysis unit


The Drug Analysis Section analyzes substances suspected of containing an illegal or controlled dangerous substance.  Each analyst in the section analyzes, and interprets their own cases.  The conclusions are formalized in a written report which is issued to the submitting law enforcement agency.

Approximately 50% of all cases submitted to the Crime Lab request analysis for illegal drugs.  Samples submitted come in various shapes, sizes, and forms.  They can include powders, liquids, tablets, capsules, and plant materials.  They range in size from small milligram samples to multiple pounds, or kilograms.

The most commonly abused drug in Louisiana is marijuana.  More than 50% of the drug cases submitted for analysis at the Crime Lab request marijuana testing.  The second most commonly abused drug we encounter is cocaine (especially crack cocaine).  Other drugs analyzed by the Crime Lab include narcotics like heroin, morphine, and oxycodone (Oxycontin); stimulants like methamphetamine; hallucinogens like LSD and MDMA (ecstasy); depressants like Valium and Xanax; steroids like testosterone; and date rape drugs like GHB and GBL.
