CHE-20012: Drugs of Abuse

The role of Forensic Science in the investigation of drugs and drug-related crime will be examined. This module will develop students understanding of the systematic abuse of drugs and alcohol and introduce the relevant legal issues. Aspects of pharmacology and toxicology will be introduced by examining various classes of drugs in detail, and the determination of drugs and alcohols in biological specimens will be demonstrated using appropriate methodologies and analytical techniques.
