The drugs phenomenon is one of the greatest challenges countries are confronted with in the 21 st century. It is well known that drugs use and abuse influence and negatively affect the health of people, families and communities, as well as national and international development, social stability and security (1)(2) .The globalization process can direct or indirectly facilitate drugs trade, as well as the development of money laundry mechanisms, contributing to increased drugs consumption in different population groups.
