What does MSJ look like?

These are small blue pills often with MSJ printed on one side and a blue line across the other. They can range in size from 4.5mm to 7mm across. Illicit production means that the dose isn't consistent, they may be sold as 10mg but they can actually range anywhere from 8mg to 30mg, but this will not be known until taken. As they are not regulated, some may not contain any diazepam, and some have been found to contain other Benzodiazepines and other chemicals. They may be sold in tubs, plastic bags or in blister packs.

Helping services

'Street agencies' or projects, sometimes called community drug services or community drug teams, offer a range of services including information and advice, counselling, and sometimes support groups and other services such as acupuncture. Some may have extended opening hours and may be open at weekends. GPs and hospitals can offer support and reduction programmes for coming off Benzodiazepines and can also 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 physically dependent. They provide counselling, detoxification, substitute prescribing and other treatments. 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.
