Toxicologists detect and identify drugs and poisons in body fluids, tissues, and organs. Role of forensic toxicologist is limited to matters that pertain to violations of criminal law. Metabolism: transformation of a chemical in the body to another chemical to facilitate its elimination from the body. Absorption: passage of alcohol across the wall of the stomach and small intestine into the bloodstream. Longer the total time required for complete absorption to occur, the lower the peak alcohol concentration in the blood. Oxidation: combination of oxygen with other substances to produce new products.
