Terms
• Narcotic
• An opium-based central nervous system depressant
used to relieve pain and diarrhea
• Opiate
• A class of drugs derived from opium
• Opioid
• Drugs with characteristics similar to those of opium
• Laudanum, a mixture of opium and alcohol, was
developed in the 1500s by Paracelsus
History
• The hypodermic needle hastened the effects of
morphine
• Ironically, the drug promoted to help people overcome
morphine dependency was heroin
History
• By 1906, opium and its derivatives were found in more
than 50,000 medicines
• By the late 1800s, an estimated 4.59 per 1,000 people
were dependent on opiates
History
•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

Self-reporting
Extent of Narcotic 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
• 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
Worldwide Comparison
• More than 15 million people worldwide illegally use opium,
morphine, and heroin
• China is believed to have the largest number of narcotic
addicts
• An estimated 24 million to 34 million people throughout the
world use opium
Opium
•Poppy grows throughout Asia and the
Middle East
•Seedpod is scraped, milky sap is
collected and dried to a brown resin
(opium)
•There is a ten-day window in which
opium can be extracted
Illicit Opium Production
Illicit Opium Production
Opium Poppies in
Afghanistan
Morphine
•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
• 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

Synthetic Opiates
•Fentanyl (Sublimaze)
• Synthetic narcotic 1,000 times more potent than heroin
• Greater risk of a fatal overdose than heroin
•China white
• Synthetic analgesic drug derived from fentanyl that mimics
heroin but is considerably more potent
•Meperidine
• Synthetic derivative of morphine widely used as an analgesic –
less potent than morphine
Synthetic Opiates
•Propoxyphene hydrochloride (Darvon)
• Mild narcotic that has the potential to
cause dependence
•Methadone
• Drug given to heroin addicts to block
withdrawal effects and euphoria
•Oxycodone (Percodan)
OxyContin
• OxyContin is a particularly strong painkiller that blocks the
pain signals from nerves
• Thousands have become addicted to it – the number of
addicted babies has doubled or tripled over the past decade
• The manufacturer, Purdue Pharma, admits that dozens to
hundreds of people have died from it
Dosages (add oxy)
Brain
•Mouse Party
•Opiates mimic endorphins in the brain

• Correlated with criminal behavior, unemployment, and
violence
NEPs retard the spread of
HIV/AIDS

A Day in the Life
Dependency
• Factors affecting the difficulty of withdrawal:
• Social support network
• Desire to stop
• Physical environment during withdrawal
• Alternative opiates
Dependency
• About half of narcotic abusers become dependent:
• Can develop in less than two weeks if they take increasing amounts of
narcotics
• Average addiction is six to eight years (aging out)
Toxicity
• Respiratory depression can be fatal
• Synergistic effect when combined with depressants
• Opioid Triad
• Coma
• Depressed respiration
• Pinpoint pupils
• Death from an overdose of heroin is slow – people who die
quickly are likely to die from anaphylactic shock
Toxicity (risks)
• According to the CDC, painkillers kill twice as many people as
cocaine and five times more people than heroin
• Increased risk of blood-borne disease and infections
• Physical problems frequently result from using narcotics in
unclean, unsafe environments
• Sharing needles is a major risk for HIV infection
• Narcotics often are contaminated with other drugs, sugar,
starch, powdered milk, quinine, or strychnine
Medical Benefits
• Analgesic
• Patients receiving morphine are aware of pain, but their
perception and response are altered in positive ways
• Gastrointestinal difficulties
• In less-developed countries, narcotics treat diarrhea that is a
major cause of death among the young and elderly
• Cough suppressant (antitussive)
• Narcotics slow activity of the cough control center
• Nonopiate dextromethorphan is chemically similar
Treatment and Support Groups
• The recidivism (relapse) rate for narcotic addiction is high
• Gradual detoxification - 10 to 14 days on an inpatient basis
• Rapid detoxification
Narcotic Antagonists
• Drugs that block narcotics from producing their reinforcing
effects are called antagonists
• They remove the physical need for opiates, but not the
psychic need
• Examples are (Suboxone) naltrexone, buprenorphine,
nalorphine, naloxone, and cyclazocine
Methadone – Narcotics Agonists
• Since 1960, methadone has been the drug used most
frequently to treat heroin addiction
• Methadone is highly specific to opiate addiction
• Methadone use leads to addiction, though many people
consider it preferable to heroin addiction
• Methadone has to be administered daily to avert withdrawal
symptoms
Common Narcotics
Perceptions of Narcotics
• Narcotics were
advertised as a cure for
addiction to tobacco
Extent of Narcotic Use
• Controlled users (chippers) fit the following pattern:
• Seldom used the drug more than once a day
• Could keep opiates around without using them
• Avoided opiates when addicts were present
• Did not use opiates to alleviate depression
• Seldom binged on opiates
• Knew the opiate source or dealer
• Took opiates for recreation or relaxation
• Did not take opiates to escape life’s daily hassles

Editor's Notes

  • #5 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.
  • #6 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.

With the invention of the hypodermic syringe, increased IV use.
  • #8 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.
  • #11 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.
  • #17 Afghanistan remains the world’s largest producer of opium.
  • #21 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.

  • #40 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.
  • #43 Narcotics were advertised as a cure for addiction to tobacco.
