Opium (poppy tears, lachryma papaveris) is the dried latex obtained from the opium poppy (Papaver somniferum). Opium contains up to 12% morphine, an alkaloid, which is frequently processed chemically to produce heroin for the illegal drug trade. The latex also includes codeine and non-narcotic alkaloids such as papaverine, thebaine and noscapine. The traditional method of obtaining the latex is to scratch (“score”) the immature seed pods (fruits) by hand; the latex leaks out and dries to a sticky yellowish residue that is later scraped off the fruit. The modern method is to harvest and process mature plants by machine. “Meconium” historically referred to related, weaker preparations made from other parts of the poppy or different species of poppies.

The production of opium itself has basically not changed since ancient times. However, through selective breeding of the Papaver somniferum plant, the content of the phenanthrene alkaloids morphine, codeine, and to a lesser extent thebaine, has been greatly increased. In modern times, much of the thebaine, which often serves as the raw material for the synthesis for hydrocodone, hydromorphone, and other semi-synthetic opiates, originates from extracting Papaver orientale or Papaver bracteatum.

Opium for illegal use is often converted into heroin, which is less bulky, making it easier to smuggle, and which multiplies its potency to approximately twice that of morphine. Heroin can be taken by intravenous injection, intranasally, or smoked (vaporized) and inhaled.

Opioid dependency is a medical diagnosis characterized by an individual’s inability to stop using opioids (morphine/heroin, codeine, oxycodone, hydrocodone, etc.) even when objectively it is in his or her best interest to do so. In 1964 the WHO Expert Committee on Drug Dependence introduced “dependence” as “A cluster of physiological, behavioural and cognitive phenomena of variable intensity, in which the use of a psychoactive drug (or drugs) takes on a high priority. The necessary descriptive characteristics are preoccupation with a desire to obtain and take the drug and persistent drug-seeking behaviour. Determinants and problematic consequences of drug dependence may be biological, psychological or social, and usually interact”. The core concept of the WHO definition of “drug dependence” requires the presence of a strong desire or a sense of compulsion to take the drug; and the WHO and DSM-IV-TR clinical guidelines for a definite diagnosis of “dependence” require that three or more of the following six characteristic features be experienced or exhibited:

* 1. A strong desire or sense of compulsion to take the drug;
* 2. Difficulties in controlling drug-taking behaviour in terms of its onset, termination, or levels of use;
* 3. A physiological withdrawal state when drug use is stopped or reduced, as evidenced by: the characteristic withdrawal syndrome for the substance; or use of the same (or a closely related) substance with the intention of relieving or avoiding withdrawal symptoms;
* 4. Evidence of tolerance, such that increased doses of the drug are required in order to achieve effects originally produced by lower doses;
* 5. Progressive neglect of alternative pleasures or interests because of drug use, increased amount of time necessary to obtain or take the drug or to recover from its effects;
* 6. Persisting with drug use despite clear evidence of overtly harmful consequences, such as harm to the liver, depressive mood states or impairment of cognitive functioning.

The Walid-Robinson Opioid-Dependence (WROD) Questionnaire was designed based on these guidelines.
