Following the convictions of serial killer Stephen Port and murderer Gerald Matovu, who both used GHB as their weapon, Dispatches has conducted an eight-month investigation with BuzzFeed News into the use of the drug among gay men. With the largest ever survey of GHB users, Dispatches reveals for the first time the human cost of the epidemic scale of abuse, with over a quarter of users reporting being sexually assaulted, almost half having overdosed, thousands of hospital admissions, and a hidden crime spree: rape, murder, and the live-streaming of sexual abuse. The law allows GBL to be sold for cleaning purposes, which enables easy access to industrial quantities of it online, which can then be used/sold as GHB to users. Dispatches interviews men who have been deliberately overdosed, raped, and those including Lord Brian Paddick who have lost partners and family members.
