Opiates can be divided into two groups: the naturally occurring opiates like heroin and morphine which are derived from the opium poppy and the synthetic opiates like methadone and dipipanone.
Drugs include:
| Drug name | Brand/common name | Street name | Therapeutic dose range |
| Codeine | Actifed Phensedyl Codeine Linctus Codis |
||
| Buprenorphine | Temgesic | Tems | 0.6-1.6mg |
| Dextropropoxyphene | Distalgesic Co-proximol |
||
| Dextromoramide | Palfium | Palf, peach | 5-10mg |
| Diamorphine | Heroin | Smack, H | |
| Dihydrocodeine | DF118 | DFs, diffs | 120-180mg |
| Dipipanone | Diconal | Dikies | 30mg |
| Methadone | Physeptone | Meth, phy | 15-40mg |
| Morphine | MST Continus Kaolin and Morphine Cyclimorph |
||
| Opium | Gees Linctus | ||
| Nubain | Nalbuphine hydrochloride | 1 ml vial |
| Street use | Opiates can be smoked, sniffed, inhaled or injected depending on the drug and preparation. | ||
| Drug effect | Opiates are used for their analgesic (painkilling) properties. They also reduce breathing rate and heart rate, hunger and anxiety. These effects combined with an increase in blood flow to the skin gives the warm, contented and sometimes euphoric feeling that is often reported. First time users may vomit but this stops with repeated use.
At low doses, opiates do not interfere with physical coordination or mental alertness. After high doses, opiates produce a stupor (gauching). |
||
| Dependency | Tolerance to opiates develops very quickly and after a few weeks of regular use, doses must be increased to produce the same effect.
Dependence takes longer to develop, but after taking opiates regularly for some months there are physical withdrawal symptoms. The speed with which dependence develops and the severity of withdrawal symptoms experienced depends upon the quantity and type of drug taken, the method of administration and to some extent the expectations of the user. Withdrawal usually begins eight to 48 hours after the last dose of drug, peaks after three to five days and then fades after five to 14 days. Withdrawal from opiates can be unpleasant and uncomfortable. Symptoms are similar to a bad bout of flu and include: sweating, stomach cramps, muscular pain, running nose and diarrhoea. Most symptoms fade fairly quickly but sleeplessness and feelings of weakness may continue for some months. |
||
| Long-term use | The physical effects of long-term opiate use are not often serious in themselves. Common side-effects include constipation, irregular periods (menstrual cycle) and weight loss. However the use of unsterile equipment and the injecting of adulterated heroin, crushed tablets or the contents of capsules, can lead to more serious problems, including abscesses, vein collapse, loss of limbs, hepatitis B and C and HIV infection. | ||
| Overdose risk | Deaths from opiate overdoses are relatively rare although the intravenous use of Diconal is particularly dangerous. The risk increases after a period of abstinence or when opiates are mixed with other drugs such as cocaine, barbiturates or alcohol. | ||
| Risks in pregnancy | Many women do not have periods (menstrual cycle) when they are using opiates regularly but as soon as they cut down or stop their periods return. Many female drug users become pregnant at this time.
There is no evidence that opiates cause birth defects although they may possibly increase the risk of miscarriage and still births. However, opiate use should not be stopped suddenly because this also increases the risk of miscarriage or premature labour. Gradual withdrawal over 12 weeks may be advised. Babies born to mothers who continue to “use” throughout the pregnancy show withdrawal symptoms within three days of birth (possibly longer if the mother has been using methadone). Symptoms include excessive restlessness, shrill crying, sleeplessness, constant sucking, diarrhoea, yawning and sneezing. In severe cases babies may suffer convulsions which can be fatal. |

| Overdose risk | Deaths from overdose are relatively rare, but complications associated with injecting, like hepatitis C or septicaemia, are more likely. Overdose may produce pinpoint pupils, sedation, dizziness and breathing difficulties. Its effects are increased if mixed with other central nervous system depressants such as tranquillisers, sedatives, hypnotics or alcohol. |
| Legal status | Nubain is not controlled under the Misuse of Drugs Act (1971). It is a prescription-only medicine. |
| SPECIAL NOTE | Nubain is abused particularly by people involved in competitive sports especially body builders to overcome musculo-skeletal pain despite the risk of injury, to keep calm before competition, and to take part in sport or training after injury. Nubain addicts shoot up between six to eight times a day whereas heroin users would tend to shoot up only once. This carries considerable risk of infection, hepatitis C, HIV and other infections if sharing equipment. |
