Notes:

(1) ‘Speedball’ is included in the category ‘other substances’. From the 2nd semester of 1995 two main drug centres stopped participating in the data collection; one of those centres re-entered in 2001 and the other in 2002.

(2) Data based on national census on drug addiction centres at national level in 1997, 1999; 2003.

(3) The data for 2001, 2002 and 2003 exclude general practitioners because of low coverage.

(4) Data refer to all clients in treatment and therefore they are not compatible with TDI standards.

(5) Partial comparability with TDI.

(6) Data include only substitution treatments; data refer to all clients in the reporting year and not to all clients entering treatment according to the TDI Protocol definition.

(7) Data refer to all clients in treatment and therefore they are not compatible with TDI standards.

(8) Only outpatient treatment centres are reported.

(9) Number of units covered by the data collection increased from 66 in 1998 to 163 in 2003

(10) Data before 2000 were available but they were not included because of a major change in the reporting system, which would have biased the comparisons of the data over time. The system is under development and every year new units are added to the information system.

(11) Up to 2001 data cover a 6-month period; from 2002 data cover one year.

(12) Up to 2001 data cover only Sofia; in 2002 Plovdiv and Varna were included; in 2003 Pleven; in 2003 data cover the capital and the three biggest cities.
