Description
Summary:Marijuana (Cannabis sativa L.) is the most cultivated, trafficked and consumed illicit drug worldwide. Estimates indicate 10% of individuals experiencing marijuana become daily users, and 20-30% use it weekly. Around 489 natural compounds have been identified in this plant, of which 70 are cannabinoids, responsible for psychic effects. The most relevant cannabinoid is Δ9-THC, recognized as the main chemical substance with psychoactive effects. The aims of this work was to investigate whether other drugs interfere with the colorimetric tests Fast Blue B and Duquenois-Levine, widely used for marijuana screening in forensic chemistry laboratories.
