Detection of drugs from hair samples has become an imperative technique in forensic toxicological analysis. In this study, hair samples were collected from 20 cannabis users undergoing treatment at a rehabilitation center at different time intervals. Hair samples were cleaned and digested, followed by extraction and quantification of THC by GC–MS. At LOD of 0.1 ng/mg of THC, the concentration ranged from 0.16 to 2.3 ng/mg (mean, 0.95 ng/mg). Results indicate that THC is detectable after 3 months of last drug intake
