* Figures are rounded.

"The figures include all injecting use. Heroin is still the most common drug injected, but, for more and more people, amphetamine is becoming the main drug injected. The proportion of injecting drug users in Oslo who had primarily injected amphetamine during the past month was approximately 20 per cent in 2002–2004. In 2008–2010, the corresponding figure was approximately 35 per cent (unpublished results from a study conducted among injecting drug users in Oslo, Bretteville-Jensen, SIRUS). It has also become more common to inject both heroin and amphetamine."
