Where does it come from?
Little illicit morphine finds its way into Britain, but what is found on the illicit market in this country has probably been diverted from the pharmaceutical industry, pharmacies, or GPs prescriptions.
It is rare to find a user dependent on morphine alone unless they have acquired this dependency as part of treatment for some medical condition. In such cases they will probably be treated either by their GP or by drug dependency clinics. Other regular drug injectors using heroin or other opiates may use morphine when they can get hold of it - in which case drug counselling agencies may be able to help them.
