Forensic toxicology has a number of applications. It provides clinicians with information of a possible drug taken in overdose or authorities investigating a sudden death or poisoning with the possible substances(s) used. Toxicology testing is also important in victims of crime, or in persons apprehended for a crime. Drugs may have been given by the assailant to reduce consciousness of the victim, such as in rape cases. These drugs include the benzodiazepines (e.g., Rohypnol, Valium, Ativan, etc.) and gamma-hydroxybutyrate (GHB). Toxicology also establishes if any drug was used by the victim that may have affected consciousness or behavior. Defendants arrested shortly after allegedly committing a violent crime may be under the influence of drugs. Alcohol and drugs are also commonly targeted in drivers suspected of driving under the influence.
