The document summarizes the 1996 film Trainspotting, which follows five young drug addicts living in Edinburgh, Scotland. It introduces the main characters: Renton, a heroin addict; Begbie, a violent non-user; loyal Spud; complacent Sick Boy; and Tommy, who eventually tries heroin. The film realistically depicts the harsh realities of drug use, like an infant's death going unnoticed. Heroin is described as creating euphoria but also severe withdrawal symptoms and overdoses requiring the opioid antagonist naloxone. The financial and criminal costs of heroin addiction are also discussed.
