Application of a validated LC-MS/MS method for JWH-073 and its metabolites in blood and urine in real forensic cases

Abstract

Synthetic cannabinoids, which were synthesized to improve the therapeutic effects of cannabis, have become a major issue when they are abused. They have different chemical structures from tetrahydrocannabinol (THC) but similar effects on endocannabinoid receptors. "Spice'' named products have more serious side effects than cannabis and can even cause death. These mixtures are prepared by spraying chemicals onto small pieces of herbs and are being dishonestly sold as "natural'' and "legal'' products over the internet. Their popularity is continuously increasing. Studies on detecting synthetic cannabinoids in biological samples as well as pharmacology and toxicology studies of these chemicals are very limited.
