The documentary series "The Fix" is based on the book "Chasing the Scream: The First and Last Days of the War on Drugs" by British journalist and writer Johann Hari. This is a story narrated by Samuel L. Jackson in the first person, debunking common misconceptions about drugs and the role of addiction in the United States. The characters emphasize that the main causes of destructive addictions lie in loneliness. Drug use is essentially a way to adapt to a frightening social environment.
