Officers in the New South Wales Police Force are exposed to drugs and other chemicals during the course of their duties through direct contact with materials during search and seizure or arrests, handling of stored exhibits and exposure to contaminated surfaces or air.
This project considered the extent of exposure by sampling workspaces for drug residues and considering the concentrations found on skin and in urine and hair provided by volunteer officers. A suite of 23 licit and illicit drugs and metabolites were considered including opiates, amphetamines, benzodiazepines, cocaine, ketamine and cannabis.
Six city Local Area Commands and five regional Local Area Commands (LACs) were each sampled on three occasions and the results were compared to four community 'baseline' sites. Sampling consisted of alcohol swabbing of potentially contaminated surfaces such as counters, desks, computers, safes and vehicles and the collection of air samples from safes and large drug stores.
In addition, sampling targeted a number of higher risk activities where larger volumes of drugs may be encountered such as drug destruction, raids at hydroponic cannabis houses and three week-long operations as part of the Cannabis Eradication Program.

The researchers found that, while the results for the vast majority of samples was down in the area of what was normal for police stations, they found out valuable information about the areas of the stations most likely to be contaminated.
Recommendations about how to change procedures to reduce the risk of exposure for officers include:

Presented at the International Association of Forensic Toxicologists and the Society of Hair Testing Conference, Aug 28 to Sept 1, Brisbane.
The work from this study has provided recommendations for procedural changes to decrease the likelihood of accumulation of drugs on work surfaces and in the air, and hence, exposure to police officers. These changes may include how seized drugs are handled, stored and transported to minimise the risk of exposure.
