* Figures for heroin and crack may be underestimates as the types of groups that use these drugs, eg people living in homeless hostels, tend not to overlap with crime survey respondents.
** Mentioned on death certificate where cause of death is listed as drug poisoning. More than one drug may have been present so, for example, a death involving heroin but where cannabis was also found will show up in both heroin and cannabis figures. Cocaine and crack cocaine are indistinguishable in the body after death so are not shown separately. The total number of deaths for England and Wales includes anti-depressants and painkillers such as paracetamol.
