Editor's Notes
- Sometimes called opioids. Some texts differentiate between opioids = naturally derived from opium (morphine/codeine), opiates – synthetic reproductions of opioids: heroin, methadone, fentanyl, oxycontin, hydrocodone, and others. Cultivated from an annual flowering plant. Origin in the Middle East. Only available for collection for a few days of the plant’s life. Collectors use a sharp, clawed tool to make shallow cuts into the unripe seedpods. Resinous substance oozes out and is scraped and collected – raw opium. Today most heroin is produced in South America, Mexico and Southeast Asia. By 1906, opium and its derivatives were found in more than 50,000 medicines The hypodermic needle hastened the effects of morphine By the late 1800s, an estimated 4.59 per 1,000 people were dependent on opiates Ironically, the drug promoted to help people overcome morphine dependency was heroin The opium poppy, Papaver somniferum, is cultivated throughout Asia and the Middle East When the seedpod is cut open, it exudes a white, milky sap which dries to a brown, thick, gummy resin (opium) There is only a ten-day window in which opium can be made from the resin of the opium poppy In 1803, Friedrich Serturner of Germany synthesized morphine from opium and called it morphium Morphine is about ten times more potent than opium, although physicians thought it was safer and purer Codeine was isolated from opium 30 years later How morphine is administered and its dosage has a bearing on its effectiveness Heroin (diacetylmorphine) was first synthesized from morphine in 1874 When heroin was introduced, it was believed not to be addicting When smoked, its effects are rapid – it is ineffective when ingested Heroin is three to ten times more powerful than morphine because it is more lipid-soluble
- Available in patent medications Increased in 1850 as Chinese laborers arrived in the US Dependence not viewed as a major social problem Opium smoking was limited to certain groups Patent medicines were socially acceptable Opioid dependence was viewed as a “vice of middle life” Typical user was a 30-to-50-year-old middle class white woman, wife, and mother Drugs purchased legally in patent medicines High drugs levels in patent medicines meant that withdrawal symptoms were severe and relieved only by taking more Thomas de Quincey 1823 drank laudanum and wrote a book Life of an Opium Eater. Seen as a vice of middle age. By 1906, opium and its derivatives were found in more than 50,000 medicines The hypodermic needle hastened the effects of morphine By the late 1800s, an estimated 4.59 per 1,000 people were dependent on opiates Ironically, the drug promoted to help people overcome morphine dependency was heroin
- Opium was outlawed in China in 1729 The British East India Company was involved in opium trade in India & China, eventually led to war between British and Chinese Morphine is the active ingredient in opium and was isolated in 1806. It’s 10 times as potent as opium. It was named morphium after Morpheus the God of Dreams. In 1832 another alkaloid of opium was discovered and named codeine “poppy head” The hypodermic syringe was invented in 1853 allowing for IV use of morphine. Medically useful characteristics Clinically useful Pure chemical Known potency Use spread due to two developments 1853: Hypodermic syringe allowed delivery of morphine directly into the blood Widespread use during war provided relief from pain and dysentery Many veterans were dependent on morphine, and dependence was later called “soldier’s disease” or “army disease” Two acetyl groups added to morphine given the brand name Heroin and marketed by Bayer 1898. 3X more potent than morphine because the increased lipid solubility of the heroin molecule easily passes the Blood-Brain Barrier. Acts more quickly. Was originally marketed as a non-habit forming substitute for codeine. Most of today’s heroin comes from South America, Mexico and Southeast Asia. Average purity has increased from about 5% to 25% since the 70s. In 2008, retail purity for Mexican heroin 40% and South American heroin 57%. With the invention of the hypodermic syringe, increased IV use. 68% of heroin addicts admitted into treatment are male, 59% are White, and ¾ have been in treatment previously Increase in abuse is significantly higher in rural areas than in metropolitan areas During the Vietnam War, 10-15% of US troops were addicted to heroin More than 15 million people worldwide illegally use opium, morphine, and heroin Afghanistan is the largest heroin producer worldwide China is believed to have the largest number of narcotic addicts An estimated 24 million to 34 million people throughout the world use opium
- Made these drugs available only by prescription. This changed the pattern of opioid use. The only source for these drugs without a prescription was illegal drug dealers. Oral use declined and the primary remaining users were IV users of morphine or heroin. Cost and risk of use increased and so the most potent method of use was favored. Addicts were seen as weak and self-indulgent. Oral use declined and use in low-income areas of large cities increased. By the 60s, heroin use was associated with crime and considered socially unacceptable. The Harrison Act of 1914 made narcotic use without a prescription illegal The typical opiate addict shifted from a middle-class woman to a young, lower-class man Perceptions of the opiate addict went from unfortunate victim to a deviant criminal who was a threat to society During the 1930s, morphine abuse exceeded heroin abuse – by the 1940s, heroin addiction was greater Heroin use increased greatly beginning in the late 1960s and early 1970s. In 2010, about 200,000 Americans had used heroin in the previous month In the US, more than 800,000 people are addicted to heroin and other narcotics
- Heroin was inexpensive and relatively pure. 95%. Most users smoked or sniffed the drug. Contrary to popular opinion, Vietnam showed that under certain conditions a relatively high number of individuals will use opioids recreationally and that dependence and compulsive use are not inevitable among occasional users.
- 5% report non-medical use – given as prescription pain relievers/analgesic Most are given orally as prescriptions Dependence & toxicity from misuse – users misuse by crushing and smoking or snorting the pills Police in WW report that prescription opioids are selling for high prices on the street. $1 per mg, so a 20 mg pill would sell for $20. Have seen an increase in opioid abuse/dependency. Most anecdotal stories involve individuals who began with prescription drug use, misused or abused the prescription, and found it expensive to obtain on the streets/illegally. Many then turn to heroin in order to avoid withdrawal. Heroin is much cheaper, but is also unpredictable as far as potency and purity.
- Naturally occurring opioid-like products of the nervous system and endocrine glands activate brain opioid receptors Enkephalins: morphine like neurotransmitters found in the brain and adrenals Endorphins: morphine like neurotransmitters found in the brain and pituitary gland
- Pain relief Reduces the emotional response to pain and diminishes the patient’s awareness of, and response to, the aversive stimulus Typically causes drowsiness but does not induce sleep Treatment of intestinal disorders Reduces colic and counteracts diarrhea and the resulting dehydration Acts by decreasing the number of peristaltic contractions An opium solution known as paregoric is still available for relief of diarrhea Cough suppressant Codeine has long been used to reduce coughing It remains available in prescription cough medications Nonprescription cough remedies contain the opioid analogue dextromethorphan It produces hallucinogenic effects at high doses
- Physical and psychological dependence, and tolerance develop quickly Positive reinforcement Negative reinforcement Withdrawal symptoms can be severe Tolerance Tolerance develops to most effects from both medical and recreational usage Higher doses needed to maintain effects Cross-tolerance exists among all the opioids Psychological processes play a key role in tolerance Dependent individuals develop a conditioned reflex response to the stimuli associated with taking the drugs Physical dependence Symptoms of withdrawal appear in sequence following the timing of the most recent dose and the individual’s history of use Opioid withdrawal is unpleasant but rarely life-threatening Methadone (long-lasting synthetic opioid) produces withdrawal symptoms that appear later and are less severe than those from heroin Psychological dependence Positive reinforcement Positive effects reliably follow use of the drug Negative reinforcement Use of the drug removes withdrawal symptoms Fast-acting injectable opioids are most likely to lead to dependence Factors affecting the difficulty of withdrawal: Availability of a social support network Addict’s desire to stop Physical environment during withdrawal Convenience and practicality of alternative opiates About half of narcotic abusers become dependent: People can become drug-dependent in less than two weeks if they take increasing amounts of narcotics Average addiction is six to eight years Narcotics relieve psychic distress arising from anxiety, hostility, feelings of inadequacy, and aggression Heroin addicts have difficulty regulating inhibitions and frequently make risky decisions Users sometimes ignore or become alienated and hostile toward friends and family members Heroin use has been associated with criminal behavior, unemployment, and violence Acute toxicity Opioids depress respiratory centers in the brain Breathing becomes slower and shallower Effects with alcohol are additive Opioid overdose triad Coma Depressed respiration Pinpoint pupils Clouding of consciousness Occasionally, nausea and vomiting Can be counteracted with naloxone Narcotics cause drowsiness, vomiting, nausea, and difficulty concentrating Euphoria is followed by gradually anesthetizing sensations, then sleep and lethargy Opiates impede the ability to urinate, and can cause potentially serious constipation Male addicts have difficulty achieving an erection Chronic toxicity is associated with injection method of use Infections and the spread of blood-borne diseases Narcotics are capable of depressing the respiratory system to the point of death According to the CDC, painkillers kill twice as many people as cocaine and five times more people than heroin Synergistic effect of narcotics and other drugs can be fatal Death from an overdose of heroin is slow – people who die quickly are likely to die from anaphylactic shock
- Not all users experience euphoria from initial dose Tolerance to negative effects may develop more rapidly than tolerance to positive effects Withdrawal is often similar to a mild case of the intestinal flu People usually don’t become dependent after one dose Current users: Probably about one million opioid-dependent Americans and two to three times that many heroin chippers (occasional users) 68% of heroin addicts admitted into treatment are male, 59% are White, and ¾ have been in treatment previously Increase in abuse is significantly higher in rural areas than in metropolitan areas During the Vietnam War, 10-15% of US troops were addicted to heroin More than 15 million people worldwide illegally use opium, morphine, and heroin Afghanistan is the largest heroin producer worldwide China is believed to have the largest number of narcotic addicts An estimated 24 million to 34 million people throughout the world use opium
- Reverse depressed respiration from opioid overdose Precipitate withdrawal syndrome Prevent dependent individuals from experiencing a high from subsequent opioid use SUBOXONE is a combination of two drugs: Buprenorphine: an opiate that acts to fill up the brain’s opiate receptors without causing sleepiness or “high” feelings. It has a low risk of overdose. Naloxone , a drug that is not absorbed orally but helps persuade people not to inject Suboxone in the vein as it causes instant withdrawal. Methadone (long-lasting synthetic opioid) produces withdrawal symptoms that appear later and are less severe than those from heroin. Usually administered orally. Can be abused if concentrated and injected.
- Three to four injections needed daily to prevent withdrawal Expensive habit (cost of drugs and paraphernalia) Risk of overdose due to variable potency of different batches Health problems associated with injection habit Skin infections Blood-borne infections Masking of early symptoms of illness Some users “mature out” Not all users experience euphoria from initial dose Tolerance to negative effects may develop more rapidly than tolerance to positive effects Withdrawal is often similar to a mild case of the intestinal flu People usually don’t become dependent after one dose Current users: Probably about one million opioid-dependent Americans and two to three times that many heroin chippers (occasional users)
