After inhalation, THC concentrations rise rapidly in the blood stream and even a single inhalation of a low-dose marijuana cigarette (16 mg THC) produces measurable levels. After oral ingestions THC is digested in the stomach and travels to the liver where it undergoes metabolism before entering the
