There is a symbiotic relationship between drug trafficking and money laundering, such that it is not possible to discuss one without the other. Although many other organized criminal activities generate wealth that requires money laundering, the drug trade generates the highest profits among all types of organized crime. The process of money laundering is accomplished through three main stages. The first stage of placement involves introducing the proceeds of criminal activities into the mainstream financial system. The second stage of layering involves the creation of a complex layer of financial transactions to avoid the audit trail. The third stage of integration involves recycling laundered money to the direct benefit of the launderer, making it appear to be derived from legitimate activities. Intermediaries of money laundering, such as banks and other financial institutions, are discussed. Social and economic implications of money laundering are considered, as well as the role of technology and globalization in money laundering. The importance of a global approach to prevent money laundering is emphasized. References and footnotes
