'Street agencies' or projects, sometimes called community drug services or community drug teams, offer a range of services including information and advice, counselling, detoxification and prescribing for opiate / opioid users, support groups and other services such as acupuncture. Some may have extended opening hours and may be open at weekends. GPs and hospitals can make referrals to specialist drug services like Drug Dependency Units (DDUs). These are usually located in or adjacent to a hospital and specialise in helping problem drug users, especially people who are dependent on opiate / opioid drugs. They provide counselling, detoxification, substitute prescribing and other treatments. Residential services offer treatment programmes for heavily dependent drug users who are trying to give up. Residents must usually be drug free on admission which means they usually have to undergo detoxification before entry. Programmes usually last 3-6 months, but some 12 steps programmes last longer. The types of programmes vary. Self help groups like Narcotics Anonymous (NA) co-ordinate local support groups for problem drug users around the country. Families Anonymous run similar groups for the families of drug users.
Many drug agencies also provide lots of advice and support to parents, family members and partners of people using drugs. They may provide relative support groups or advice, guidance and counselling on a one to one basis.
