"Data on treatment for problematic (or heavy) drug use at a national level is reported in TDI until 2010. In 2009 the reporting system covered 51% of all inpatient and 31% of all outpatient treatment centres. In 2010 the distribution should be similar even if the exact figures are not known.
"One third (1,597 patients) out of the total of 5,155 clients who were reported had entered treatment for the first time. The main drugs of choice by new clients are cannabis and amphetamine, closely followed by the summary category 'other opioids'.
"Most Injecting drug users (IDUs) in the population of new clients use amphetamine. For all clients undergoing treatment, the use of amphetamine is most prevalent, followed by heroin. The prevalence of amphetamine IDUs is higher than the prevalence of heroin IDUs."
