Traffic is a 2000 American crime drama film directed by Steven Soderbergh and written by Stephen Gaghan. It explores the illegal drug trade from a number of perspectives: users, enforcers, politicians, and traffickers. Their stories are edited together throughout the film, although some of the characters do not meet each other. The film is an adaptation of the 1989 British Channel 4 television series Traffik. In 2004, USA Network ran a miniseries—also called Traffic—based on this film and the 1989 British television series.
