A sensitive method to detect and quantify delta-9 tetrahydrocannabinol in oral fluid by liquid chromatography - tandem mass spectrometry

Delta9 -tetrahydrocannabinol (THC) is the major psychoactive constituent of cannabis. It causes a decrease in motor function and concentration making it hazardous for an individual to drive whilst under the inftuence of this drug. Roadside testing procedures for cannabis are therefore necessary since it is the most widely used illicit drug in Australia and around the world and is commonly implicated in drug-driving offences.
