Abstract

Aims. Information on high risk drug use in Turkey particularly at the regional level is lacking. The present analysis aims at estimating high risk cannabis (HRCU) and high risk opiate use (HROU) in the cities of Ankara, Istanbul and Izmir. Design and Methods. Capture-recapture (CRC) and multiplier methods (MM) were applied based on treatment and police data stratified by age and gender in the years 2009 and 2010. Case definitions refer to ICD-10 cannabis (F.12) and opiate (F.11) disorder diagnoses from out- and inpatient treatment records and illegal possession of these drugs as recorded by the police. Results. HRCU was estimated at 28,500 (8.5 per 1,000; 95%-CI: 7.3-10.3) and 33,400 (11.9 per 1,000; 95%-CI: 10.7-13.5) in Ankara and Izmir, respectively. Using multipliers based on CRC estimates for Izmir, HRCU in Istanbul was estimated up to 166,000 (18.0 per 1,000; range: 2.8-18.0). CRC estimates of HROU resulted in 4,800 (1.4 per 1,000; 95% CI: 0.9-1.9) in Ankara and multipliers based on these gave estimates up to 20,000 (2.2 per 1,000; range: 0.9-1-7) in Istanbul. HROU in Izmir was not estimated due to the low absolute numbers of opiate users. Discussion and Conclusions. While HRCU prevalence in both Ankara and Izmir was considerably lower in comparison to an estimate for Berlin, the rate for Istanbul was only slightly lower. Compared to the majority of European cities HROU in these three Turkish cities may be considered rather low.
