Drug Abuse at Sea:

Heroin



Description

Heroin is a chemical derived from opium. Opium is converted to morphine in a relatively simple chemical process that usually takes place in a makeshift laboratory near the poppy fields. It takes about 10 kg of opium to produce 1 kg of morphine and 3 kg of morphine to produce 1 kg of heroin. Heroin is a name commonly used to describe a preparation containing diacetyl morphine base or its salts.

Heroin is similar to face powder in appearance and is perhaps slightly coarser. It comes as a white powder when pure but street heroin is usually cream to light brown in colour and is generally odourless but may have a faint vinegary smell.

 

Administration

Heroin may be smoked, inhaled or injected.

Associated Equipment

This may consist of pipes, porcelain bowls, skewers, small peanut oil lamps, rags, charred silver foil, matchbox covers, hypodermic needles, eye droppers, etc. Possession of opium utensils is in itself an offence in many countries.

Degree of Addiction

Psychological addiction: strong
Environmental addiction: strong
Physical addiction: strong
Body tolerance: high


Influence and Symptoms

Like sedatives heroin depresses the nervous system activity including reflex functions such as coughing, respiration and heart rate. It also dilates blood vessels, giving a feeling of warmth and depresses bowel activity, resulting in constipation. Those who start by smoking or snorting heroin sometimes switch to injecting it to maximise the high.

There may be needle marks on addicts' veins.

Immediately after taking the drug the user's eyes will become constricted. Subsequently the pupils will dilate and the drug will induce a drowsy torpid state in the addict, with dilated pupils, constipation and a slow response to stimuli. Heroin is very addictive and can dominate a user's life, resulting in them taking the drug just to feel normal. In the longer term loss of appetite and general apathy may result in the addict becoming emaciated and in poor health with poor hygiene. Symptoms are similar to influenza or malaria but longer lasting effects will appear if the drug is withdrawn. Excessive use can result in overdose, coma and possibly death.

 

Injecting adds the risk of dangerous infections being spread such as HIV and hepatitis B or C if equipment is shared.

 

 

Popular Myths

Fiction: The high purity of black market opiates is guaranteed
Fact:   Purity at street level varies greatly. Sugar, caffeine, milk powder, benzocaine, diazepam and phenobarbitone are known adulterants to so- called 'pure smack' (diamorphine)
   
Fiction: It is easy to be cured
Fact:   Research shows that of treated addicts, 10% have stayed off for more than six months but only 2% or 4% for more than two years

Fiction: The substance is not really dangerous
Fact:   The average life expectancy of a heroin or morphine addict is about 6-8 years. Some can survive much longer. Many die within 4-5 years. HIV can be transmitted by using infected needles or syringes
