Nalorphine was the first compound used for narcotic (heroin in particular) overdose treatment however, it exhibits a number of side effects such as visual hallucinations, and therefore its use is prohibited in some countries. The most popular synonym for this drug is narkan.

Choice of substance can make a difference. Although most any substance (and activity) can become psychologically addictive, only some tend to become physically addictive. Stimulants (cocaine, for example), depressants (alcohol, for example), and narcotics (heroin, for example) are more likely to become physically addicting than inhalants (paint thinner, for example) or hallucinogens (LSD, for example). Whether marijuana can be physically addictive seems open to debate (it meets the criterion of tolerance but not withdrawal, see "physical addiction" on page 53). 

Classes of substances currently banned by the IOC include stimulants (amphetamines, cocaine, caffeine, pseudoephedrine), narcotics (heroin, methadone), anabolic agents (testosterone, nandrolone), diuretics (acetazolamide, spironolactone), and peptide hormones and their mimetics and analogs (erythropoietin, human growth hormone). Alcohol and marijuana at specified levels are also prohibited. For the latter, a level of as little as 15 ng/mL of 11-nor-A°-tetrahydrocannabinol-9-carboxylic acid is a violation of the rules.

Morphine, when extracted from raw opium and treated chemically, yields the semisynthetic narcotics hydromorphone, oxymorphone, oxycodone, and heroin. Heroin is an illegal narcotic in the United States and is not used in medicine. Synthetic narcotics are those man-made analgesics with properties and actions similar to the natural opioids. Examples of synthetic narcotic analgesics are methadone, levorphanol, remifen-tanil, and meperidine Additional narcotics are listed in the Summary Drug Table Narcotic Analgesics.

Heroin, a synthetic derivative of the p opioid receptor agonist morphine, is a well-documented narcotic that alters mood and rewarding behaviors. To date, heroin is the most abused opioid with an estimated 750,000-1,000,000 hardcore users in the... 

Finally, intravenous drug administration and the sharing of needles and syringes is common among opiate addicts this creates a serious risk of cross-infection. Many studies have shown a high incidence of HIV and hepatitis B and C among heroin addicts. This risk is somewhat reduced in medically controlled narcotic prescription... 

The PE spectra of some other alkaloids like methadone and the opiate narcotics morphine, codeine and heroin have been investigated by Klasinc and coworkers95. Also in this study structure-activity relationships based on IPs were sought but not found. Since the interaction of the drug molecule with the receptor is highly specific, it is not unreasonable that the molecular rather than the electronic structure is more important for the physiological activity.

Methadone (Dolophine). For over 30 years, methadone has been the mainstay of treatment for opiate dependence. A replacement therapy, methadone has been used both for detoxification and for long-term maintenance. It has a slower onset of action and is longer acting than other narcotic analgesics. It causes little of the euphoria produced by drugs such as heroin. 

The use of scheduled substances in the illicit manufacture of narcotic drugs and psychotropic substances, depicted in figures A.I-A.IV below, represents classic production and manufacturing methods. The extraction of cocaine from coca leaf and the purification of coca paste and the crude base products of cocaine and heroin require solvents, acids and bases. A wide range of such chemicals has been used at all stages of drug production. 

The most known narcotics are the opium alkaloids such as morphine, codeine, thebaine, papaverine, noscapine and their derivatives and modified compounds such as nalmorphine, apomorphine, apomopholcodine, dihydrocodeine, hydro-morphone and heroine, also known as diamorphine. Synthetic narcotics share the structural skeleton of morphine and include dextromethorphan, pentazocine, phenazocine meperidine (pethidine), phentanyl, anfentaitil, remifentalin, methadone, dextropropoxyphene, levoproxyphene, dipipanone, dextromoramide, meptazinol and tramadol. Thebaine derivatives are also modified narcotics and include oxycodone, oxymorphone, etorphine, buprenorphine, nalbuphine, naloxone or naltrexone. Narcotics can be semi-synthesized or totally synthesized from the morphine and thebaine model. The compounds serve various purposes in clinical practise.

For centuries opium was used for both medicinal and recreational purposes. Derived from the poppy Papaver somniferum, it contains numerous opiates, the primary one of which is morphine. The term opiate has largely been replaced by opioid, which represents all compounds with morphinelike activity and includes morphine, morphine derivatives, and peptides. Opiate is used to refer to morphinelike drugs derived from the plant and structurally similar analogues. These drugs are frequently referred to as narcotics, a Greek term for stupor, which is scientifically obsolete. Even in its early history, opium presented a problem when it was smoked or taken orally. The introduction of the hypodermic needle and syringe, however, drastically enhanced the euphoric properties of opioids and thereby altered their abuse liability. In addition, the synthesis of heroin resulted in an opioid that was more potent than morphine and ideally suited for intravenous administration. 

As a result, the temperance movement in the United States, in the early twentieth century led to increased legislation to curb the use of opium and its derivatives. In 1905, the U.S. Congress banned the sale of opium, and the Harrison Narcotics Act of 1917 required patients to receive prescriptions for potentially harmful drugs. By 1923, most narcotic substances, including heroin and morphine, were banned from over-the-counter sale. 

An alkaloid is a complex organic chemical substance found in plants, which characteristically combines nitrogen with other elements, has a bitter taste, and typically has some toxic, stimulant, analgesic effects. There are many different alkaloids, 30 of which are found in the opium plant. While morphine is the most important alkaloid in opium—for its natural narcotic qualities as well as providing the chemical structure for heroin—another alkaloid, codeine, is also sought after for its medicinal attributes. Other alkaloids include papaverine, narcotine, nicotine, atropine, cocaine, and mescaline. While the concentration of morphine in opium varies depending on where and how the plant is cultivated, it typically ranges from 3 percent to 20 percent.
