This is an extract of one chapter of a report by the Center for the Study of Democracy. The report is dedicated to one of the most serious problems of the Bulgarian transition towards market economy, stable democratic institutions and legal state. The exploding growth of trans-border crime during the last 12 years has led to the emergence of criminal infrastructure, developed and maintained by criminal groups and semi-legal "power groups," which have appeared in the mentioned period. The chapter looks at drug routes through Bulgaria.
