Drugs, Inc. is an American documentary style television series on the National Geographic Channel that explores global narcotics production and trafficking. The series features drug dealers, recreational users, and addicts, as well as professionals in the fields of substance abuse, drug rehabilitation, and criminal justice. Interview subjects frequently have their voices changed or hide their faces behind masks or bandanas, in order to avoid public exposure or arrest by the local authorities.

Each episode of seasons 1 and 2 focused on a specific drug, while episodes in the following seasons investigated multiple drugs in each city or location.

A sister series, Underworld, Inc., focused on criminal activity of specific types and/or in individual cities.
