Helping services

Most areas of the UK have 'street agencies' or projects (sometimes called community drug services or community drug teams) which offer a range of services including information and advice, counselling, needle exchanges and sometimes support groups and complementary therapies such as acupuncture. Some agencies offer specialist services such as counselling, cognitive behaviour therapy, acupuncture and other alternative therapies and prescribing of anti-depressants, and also possible referral to residential rehabilitation. Some services have extended working hours and may offer weekend support. GPs and possibly the local hospital A&E department can make referrals to specialist drug services as well as general medical services, information and advice often in partnership with a drug agency or Drug Dependency Unit.

Parents & other relatives

Drug agencies also provide lots of advice and support to parents of people using these drugs. Many street agencies can provide relative support groups or counselling for family members, partners etc...
