A 25-year-old Queensland police constable is facing 38 charges after a joint investigation by the Crime and Corruption Commission (CCC) and the police ethical standards command.
CCC chairman Alan MacSporran issued a detailed statement on the matter, describing the alleged offences as "serious".
The CCC said the matter was identified by the Queensland Police Service (QPS) and referred to the CCC.
Their joint investigation focused on allegations of drug use by the constable.
The statement said investigators would also allege the constable inappropriately accessed the police database, stole police property and committed a firearm offence.
The officer is charged with nine counts of possessing a dangerous drug, 20 counts of supplying a dangerous drug, and one count each of computer hacking, stealing and unlawful possession of a weapon.
CCC boss reminds police of their obligations to community
The statement said that the matter was now before the courts and the CCC would not comment further, but Mr MacSporran said the vast majority of Queensland police officers acted with "integrity".
He said recreational use of drugs occurred in all sectors of society and officers needed to be conscious of their obligations.
"Apart from the potential work, health and safety issues of working in a frontline policing role in the days after consuming drugs, any officer involved in this type of conduct leaves themselves open to be compromised by criminals or other associates who have the knowledge that the officer is involved in the purchasing, supplying and consuming of illegal drugs," Mr MacSporran said.
The officer was formally charged on Friday at the Brisbane watch house, where they were granted bail to appear in the Brisbane Magistrates Court on August 19.
