The total number of opiate users has increased from 1998 to 2007 after which it has remained more or less stable.

Michael Agar once described heroin as “the perfect whatever drug. Equipotent injected doses had comparable action courses, with no difference in subjects’ self-rated feelings of euphoria, ambition, nervousness, relaxation, drowsiness, or sleepiness. Short-term addiction studies by the same researchers demonstrated that tolerance developed at a similar rate to both heroin and morphine. Morphine and heroin were also much more likely to produce euphoria and other positive subjective effects when compared to these other opioids.
Some researchers have attempted to explain heroin use and the culture that surrounds it through the use of sociological theories. By analyzing a community in San Francisco, they demonstrated that heroin use was caused in part by internal and external factors such as violent homes and parental neglect. This lack of emotional, social, and financial support causes strain and influences individuals to engage in deviant acts, including heroin usage.

It is sometimes thought that heroin users can walk into a clinic and walk out with a prescription, but the process takes many weeks before a prescription for diamorphine is issued. 1926 established the British approach to diamorphine prescription to users, which was maintained for the next 40 years: dealers were prosecuted, but doctors could prescribe diamorphine to users when withdrawing from it would cause harm or severe distress to the patient. This “policing and prescribing” policy effectively controlled the perceived diamorphine problem in the UK until 1959 when the number of diamorphine addicts doubled every 16 months during the ten years from 1959 to 1968. The law was made more restrictive in 1968. The aim of this program was to maintain the health of the user by avoiding medical problems stemming from the illicit use of diamorphine. The first trial in 1994 involved 340 users, although enrollment was later expanded to 1000, based on the apparent success of the program.
