What is it?
Heroin is an opiate, a drug that can relieve pain and bring about sleep, which is produced from the opium found in the opium poppy. Opium is the first product of the poppy, followed by morphine - which is around ten times stronger than opium - and finally heroin - which, in its purest form, is around three times stronger than morphine.
Opium has been used for medicine and for recreation for thousands of years, and, as a medicine, was once as popular as aspirin is today. In Britain it usually came as Laudanum, a medicine of opium mixed with alcohol.
During the eighteenth and early nineteenth century, the British were the world's biggest opium trafficker, even declaring war on China when the Emperor tried to ban the British from selling the drug to his country.
Morphine was used as a cure for opium addiction and heroin has been used as a cure for morphine addiction. Morphine has also been used, again in the nineteenth century, for recreational reasons and wealthy society women went as far as to have jewellery specially made to hold their morphine injecting equipment when at the theatre or other social gathering. There was the belief at the time that only smoking morphine would lead to a habit, not injecting.
Heroin and other opiates first came under control in the First World War as the government were worried about the effect it would have both on soldiers fighting in France and on people in Britain who were making weapons and ammunition.
Following a series of meetings about international narcotic control and the role of doctors, Britain set up a committee to look at the way forward in this country. The Rolleston Committee reported that they believed there was only one type of addict - middle-class, middle-aged, often from the medical profession and a morphine user. With about 500 such people in the country, the committee recommended that they be prescribed heroin or morphine and long-term if thought necessary.
This lasted until the late 1950's when the first new wave of heroin users became apparent. Another committee was set up to look at the problem and, in 1961, the recommendations of the Rolleston Committee were repeated. By 1965, however, the number of heroin users had grown markedly and a new system of specialist Drug Dependency Units soon opened up.
A second wave of heroin users arose during the mid-seventies as Britain was experiencing huge unemployment amongst the working class. The middle-eastern conflicts meant that more heroin became available as countries sought to get funds to buy arms and it was smokeable which made it more "acceptable" than injecting.
And the rest, so they say, is history. There are now an estimated 300,000 or so heroin dependents in England and Wales.
