A drug dealer is an individual who sells illegal substances, such as cocaine, heroin, or marijuana. These substances are often classified as controlled drugs due to their potential for abuse and addiction. Drug dealers may operate independently or as part of larger criminal organizations, and their activities can have significant legal consequences. The actions of drug dealers contribute to various social issues, including addiction, crime, and health problems within communities. Law enforcement agencies work to combat drug trafficking through arrests and prevention programs, aiming to reduce the availability of illegal drugs and support affected individuals in seeking help.
