Quantitative determination of delta 9-tetrahydrocannabinol in cadaver blood

We have described a highly sensitive, accurate, and selective method for the determination of delta 9-THC in postmortem blood. Although the method requires the use of fairly complex and sophisticated equipment, the procedure is straightforward and has been reproduced many times in our laboratories. It is thought that this procedure will serve as a useful adjunct to the forensic scientist in his armamentarium for determining physiological levels of important, abused drugs in postmortem analysis.
