Ambulance Victoria says it has undergone its drug and alcohol policies after 15 paramedics in 2017 were trapped using and trafficking drugs from ambulance deliveries, including temazepam, oxycodone, fentanyl and morphine.
Some also stole intravenous bags to treat hangover who were hit by colleagues, family or friends, according to Victoria's Independent Broad-Based Anti-Corruption Commission.
Ambulance Victoria has since faced drug and alcohol screening of its employees, with 198 tested in March and random tests to continue on a weekly basis.
The organization said Monday that the pharmacies had been recruited to reduce paramedical involvement in ordering and tracking limited medicine.
A Professional Behavior Unit was also created to allow staff to report abuse anonymously.
An electronic medica survey and staff training on limited drugs will be introduced later this year.
The measures were described in a status report to IBAC after the watchdog has marked theft of controlled substances for personal use or sale as a significant corruption risk.  Of the 15 paramedics from the Barwon South West region, involved in drug abuse and trafficking in human beings, dismissed and eight resigned.
Another six received a formal warning, and some were sent to work in different regions and reviewed ethical advice.
