Drug purchasing, also known as drug dealing or drug trafficking, is the illegal trade of controlled substances. It can involve the cultivation, manufacturing, distribution, and sale of drugs. Drug dealing is a major source of income for criminal organizations, and it can have a devastating impact on individuals and communities.
The illegal drug trade is a global problem. According to the United Nations Office on Drugs and Crime, the global illicit drug market is worth an estimated $400 billion to $500 billion per year. The most commonly trafficked drugs include cocaine, heroin, marijuana, and methamphetamine.
