    Introduction to Drug Investigation

    • This presentation covers the primary objectives of a criminal investigation and the procedure for conducting the investigation.

    Classification of Drugs

    • There are three basic categories of drugs, classified by their effect on the central nervous system:
      • Depressant drugs
      • Stimulant drugs
      • Hallucinogenic drugs

    Depressant Drugs

    • Depressant drugs slow down the central nervous system reactions.
    • Examples:
      • Narcotic drugs (opium, morphine, heroin, codeine, analgesics)
      • Non-narcotic depressants (barbiturates, tranquilizers, alcohol)
    • Possible side effects:
      • Slurred speech
      • Disorientation
      • Drunken behavior without the odor of alcohol

    Stimulant Drugs

    • Stimulant drugs increase the central nervous system reactions.
    • Examples:
      • Anorectic drugs (diet pills/weight control)
      • Amphetamine drugs (biphetamine, dexedrine)
      • Cocaine (local anesthetic)
    • Possible effects:
