The field service is aimed mainly at people who use drugs and their loved ones with no access to stationary harm reduction centres or other services of assistance, or who for some reason do not wish to visit a harm reduction centre. 

The aim of the service is to reduce harms and risks associated with drug use, provide counselling on topics such as safer drug use and overdose prevention, offer as appropriate a selection of health care and social services as possible, and motivate people with substance use issues to seek treatment.

• provision of information about harm reduction centres and their services, 
• counselling on safer use of drugs, 
• counselling on overdose prevention, 
• provision of naloxone and relevant training, 
• needle and syringe exchange, 
• distribution of injecting equipment, 
• distribution of condoms and other equipment, and assisting in their proper use, if needed, 
• counselling on diseases and sexual health care,
