Identifying the ingested substance ingested is frequently challenging due to the body's natural processes (as outlined in ADME). It is uncommon for a chemical to persist in its original form once inside the body. For instance, heroin rapidly undergoes metabolism, ultimately converting to morphine.
Forensic toxicology is the study of the pharmacodynamics, or what a substance does to the body, and pharmacokinetics, or what the body does to the substance. To accurately determine the effect a particular drug has on the human body, forensic toxicologists must be aware of various levels of drug tolerance that an individual can build up as well ...
An unknown sample found at a crime scene is called a questioned sample. A known sample can be taken either from a suspect or found in a database. The FBI’s database used for DNA is CODIS, Combined DNA Index System. It has data at three levels: local, state, and national. The national level data is stored in NDIS, National

Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
