Quantities and sentencing

Information about drug quantities and court outcomes.

The amount of a particular drug that a person is alleged to have possessed has a significant impact on the penalty. The Drugs, Poisons and Controlled Substances Act 1981 (Drugs Act) makes a distinction between:

  • small quantities
  • traffickable quantities
  • commercial mixed
  • commercial pure
  • large commercial mixed
  • large commercial pure.

The exact amounts that are set for these quantities of a drug are set out in schedule Eleven of the Drugs Act. See particularly Part 2 (for cannabis and other narcotic plants) and Part 3 lists other common illicit drugs in powder form and refers to both pure and mixed substances. Part 1 lists the drugs that are categorised by pure weight.
