Veterinarians who purchase, administer or supply drugs of addiction (controlled drugs or S8 medication) must keep a register.

The Poisons and Therapeutic Goods Regulation 2008 (cl 111) states that the register must be in the form of a book with consecutively numbered pages, bound so that the pages cannot be removed or replaced without trace, contains provision for inclusion of information required for each entry, and that there are separate pages for each drug of addiction and for each form and strength of the drug.
