What term is used for someone who illegally sells dangerous drugs?

The term used for someone who illegally sells dangerous drugs is "Drug Trafficker." This terminology is widely recognized in legal and law enforcement contexts, referring specifically to individuals or groups involved in the distribution and sale of controlled substances in violation of drug laws. Drug traffickers operate outside the legal framework, often engaging in organized crime and posing significant public health risks due to the nature of the substances involved and the methods of distribution.

In contrast, a dispensing pharmacist is a licensed professional responsible for dispensing prescription medications following legal and ethical guidelines, making this option unrelated to illegal activities. A performance artist focuses on artistic expression and has no correlation with drug sales. A professional researcher, similarly, is engaged in legitimate academic or clinical investigations, often within a legal and regulatory framework concerning controlled substances, but does not sell or distribute drugs illegally.
