Opium
Morphine Codeine Heroin
Heroin AbuseHeroin is classified as a Schedule I drug.
One of the most widely abused illegal drugs in the world; accounts for >$120 billion sales/year
Illicitly used more than any other drug of abuse in the United States (except for marijuana) until 20 years ago, when it was replaced by cocaine
Some of the recent increases in heroin use likely due to increased abuse of prescription opioid painkillers
Heroin Combinations Pure heroin is a white powder.
More than 90% of world’s
heroin is from Afghanistan.
Heroin is usually “cut” (diluted)
with lactose.
When heroin first enters the
United States, it may be 95%
pure; by the time it is sold, it
may be 3% to 70% pure.
If users are unaware of the
variance in purity and do not
adjust doses accordingly,
results can be fatal.
Heroin Combinations (continued)
Heroin has a bitter taste and is often cut with
quinine, which can be a deadly adulterant.
Heroin plus the artificial narcotic fentanyl can
be dangerous due to its unexpected potency.
Heroin is most frequently used with alcohol.
Heroin combined with cocaine is called
“speedballing.”
Facts About Heroin Abuse
What is the estimated number of heroin addicts in the United
States?
600,000 What are “shooting galleries”?
Locations that serve as gathering
places for addicts
Heroin and Crime Factors related to crime:
Pharmacological effects encourage
antisocial behavior that is crime-related
Heroin diminishes inhibition
Addicts are often self-centered, impulsive,
and governed by need
Cost of addiction
Similar personality of criminal and addict
Patterns of Heroin Abuse
Heroin has become purer (60% to 70% purity) and cheaper
(~$10/bag).
Greater purity leads users to administer heroin in less efficient ways.
Many youth believe that heroin can be used safely if not injected.
Patterns of Heroin Abuse
(continued)
Because of its association with popular fashions and entertainment,
heroin has been viewed as glamorous and chic, especially by many
young people, although lately this attitude has been changing.
Emergency room visits due to narcotic overdoses were over 190,000
in 2009.
Stages of Dependence Initially, the effects of heroin are often unpleasant.
Euphoria gradually overcomes the aversive effects.
The positive feelings increase with narcotic use, leading to psychological dependence.
In addition to psychological dependence, physical dependence occurs with daily use over a 2-week period.
If the user abruptly stops taking the drug after physical dependence has developed, severe withdrawal symptoms result.
Methods of
Administration
Sniffing the powder
Injecting it into a muscle
(intramuscular)
Smoking
Mainlining (intravenous
injection)
Heroin Addicts and AIDS More than 250,000 patients in United States contracted AIDS by drug
injection, of which most were heroin users.
Fear of contracting HIV from IV heroin use has contributed to the increase in smoking or snorting heroin.
Many who start by smoking or snorting progress to IV administration due to its more intense effects.
Heroin and Pregnancy Heroin use by a pregnant woman leads to:
Physical dependence on heroin in the newborn
Withdrawal symptoms after birth in the newborn (Note: similar withdrawal occurs in newborns of any woman who uses significant amounts of opiate drugs during pregnancy, including prescribed opiate painkillers)
At one time, heroin
was given to morphine
addicts to help them
break their addiction to
morphine.
