Abstract: ’Drug problems have no age limits’ – This special review published alongside the 2010 Annual report, reveals why drug use is no longer simply a ‘youth phenomenon’. Europe is experiencing a pronounced ageing of its population, around a quarter of which will be aged 65 or over by 2050. Statistics published today show that Europe’s drug-using population is also ageing and that meeting the needs of older drug users is a growing issue for treatment services. This is particularly the case in western countries which saw the EU’s first heroin epidemics in the 1980s and 1990s.
