Q) What is heroin?
A) Heroin is an illegal, highly addictive opiate
drug. Its abuse is more widespread than any other opiate.
Heroin is processed from morphine, a naturally occurring
substance extracted from the seed pod of certain varieties of
poppy plants. It is typically sold as a white or brownish
powder or as the black sticky substance known on the streets
as "black tar heroin." Although purer heroin is becoming more
common, most street heroin is "cut" with other drugs or with
substances such as sugar, starch, powdered milk, or quinine.
Street heroin can also be cut with strychnine or other
poisons. Because heroin abusers do not know the actual
strength of the drug or its true contents, they are at risk of
overdose or death. Heroin also poses special problems because
of the transmission of HIV and other diseases that can occur
from sharing needles or other injection equipment.

Q) What are the current trends for heroin
abuse?
A) A generation ago, the heroin (colloquially known as
"smack") available in the
U.S.
was barely five percent pure and used by a relatively small
percentage of young people because it had to be injected with a
needle. Now, it appears smack is back with a vengeance and it's
addicting large groups of new users.
The Office of National Drug Control Policy issued a
report (April 1992, No. 5, pp. 1-6) claiming "a massive increase in
heroin use and addiction is not likely." One reason for this was,
"...the apparent absence of new initiates (i.e., heroin users with
little or no prior drug-using experience)." However, based upon
recent news reports and other sources (see the A.T. Forum Web site
for News Updates), the ONDCP report appears to have been premature,
to say the least.
Just this past February, Attorney General Janet Reno
admitted heroin is more plentiful, purer, and less expensive than it
was just a few years ago. "If we do not counteract the heroin threat
now," she said, "we risk repeating the terrible consequences of the
1980s' cocaine and crack epidemic." Authorities estimate that heroin
addiction has increased 20 percent and worldwide production has
grown sharply, even as other illegal substance abuse is
declining.
Reports of problems have sprung-up countrywide. In
California, heroin
sold in the San Joaquin
Valley is cheap, potent,
and plentiful - business is booming in area emergency rooms as two
or three overdose cases appear each day. In
Colorado,
Boulder
County officials may
establish a methadone clinic for the first time in 16 years to deal
with increasing heroin addiction. On the East Coast, heroin is
reported to be 40 to 70 percent pure and around $10 for a small
packet. The number of heroin-related hospital emergencies has more
than doubled in New York
City and surrounding
areas.
Many drug abusers mistakenly believe inhaling heroin,
rather than injecting it, reduces the risks of addiction or
overdose. In some areas, "shabanging" - picking up cooked heroin
with a syringe and squirting it up the nose - has increased in
popularity. Street heroin carries prophetic names: "DOA," "Body
Bag," "Instant Death," and "Silence of the Lamb." Rather than
scaring off young initiates, the implied danger seems to actually
increase the drug's allure.
Q) What are some other names for
heroin?
A) "smack", "junk", "horse", "skag", "H", "China
white"
Q) So Heroin is an opiate. What are some of the
other opiates?
A) Opium, Morphine, Codeine, Merperidine , Hydrocodone
(Lortab, Vicodin), Oxycodone (Percodan, Roxicet, Roxiprin, Tylox,
Percocet), Stadol, Talwin, Dilaudid, Fentanyl, Buprenorphine,
Methadone, Propoxyphene (Wygesic, Darvocet)
Q) What are the statistics on heroin addiction in
the United
States?
A) According to the 1996 National Household Survey on
Drug Abuse, which may actually underestimate illicit opiate (heroin)
use, an estimated 2.4 million people use heroin at some time in
their lives, and nearly 216,000 of them reported using it within the
month preceding the survey. The survey report estimates that there
were 141,000 new heroin users in 1995, and that there has been an
increasing trend in new heroin use since 1992. A large proportion of
these recent new users were smoking, snorting, or sniffing heroin,
and most were under age 26. Estimates of use for other age groups
also increased, particularly among youths age 12 to 17: the
incidence of first-time heroin use among this age group increased
fourfold from the 1980s to 1995 The 1996 Drug Abuse Warning Network
(DAWN), which collects data on drug- related hospital emergency
department (ED) episodes from 21 metropolitan areas, estimates that
14 percent of all drug-related ED episodes involved heroin. Even
more alarming is the fact that between 1988 and 1994, heroin-related
ED episodes increased by 64 percent (from 39,063 to
64,013).
In 1996, it was reported that heroin was the primary
drug of abuse related to drug abuse treatment admissions in
Newark,
San Francisco,
Los Angeles, and
Boston, and it ranked a
close second to cocaine in New
York and
Seattle.
Q) How is heroin used?
A) Heroin is usually injected, sniffed/snorted, or
smoked. Typically, a heroin abuser may inject up to four times a
day. Intravenous injection provides the greatest intensity and most
rapid onset of euphoria (7 to 8 seconds), while musculature
injection produces a relatively slow onset of euphoria (5 to 8
minutes). When heroin is sniffed or smoked, peak effects are usually
felt within 10 to 15 minutes. Although smoking and sniffing heroin
do not produce a "rush" as quickly or as intensely as intravenous
injection, NIDA researchers have confirmed that all three forms of
heroin administration are addictive.
Injection continues to be the main method of use among
heroin addicts; however, researchers have observed a shift in heroin
use patterns, from injection to sniffing and smoking. In fact,
sniffing/snorting heroin is now a widely reported means of taking
heroin among users admitted for drug treatment in
Newark,
Chicago, New
York, and
Detroit.
With the shift in heroin abuse patterns comes an even
more diverse group of users. Older users (over 30) continue to be
one of the largest user groups in most national data. However,
several sources indicate an increase in new, young users across the
country who are being lured by inexpensive, high-purity heroin that
can be sniffed or smoked instead of injected. Heroin has also been
appearing in more affluent communities.
Q) What are the immediate (short-term) effects of
heroin use?
A) Soon after injection (or inhalation), heroin
crosses the blood-brain barrier. In the brain, heroin is converted
to morphine and binds rapidly to opioid receptors. Abusers typically
report feeling a surge of pleasurable sensation, a "rush." The
intensity of the rush is a function of how much drug is taken and
how rapidly the drug enters the brain and binds to the natural
opioid receptors. Heroin is particularly addictive because it enters
the brain so rapidly. With heroin, the rush is usually accompanied
by a warm flushing of the skin, dry mouth, and a heavy feeling in
the extremities, which may be accompanied by nausea, vomiting, and
severe itching.
After the initial effects, abusers usually will be
drowsy for several hours. Mental function is clouded by heroin's
effect on the central nervous system. Cardiac functions slow.
Breathing is also severely slowed, sometimes to the point of death.
Heroin overdose is a particular risk on the street, where the amount
and purity of the drug cannot be accurately known.
Q) What are the long-term effects of heroin
addiction and use?
A) One of the most detrimental long-term effects of
heroin is heroin addiction itself. Addiction is a chronic problem,
characterized by compulsive drug seeking and use, and by
neurochemical and molecular changes in the brain. Heroin also
produces profound degrees of tolerance and physical dependence,
which are also powerful motivating factors for compulsive use and
abuse. As with abusers of any addictive drug, heroin addicts
gradually spend more and more time and energy obtaining and using
the drug. Once they are addicted, the heroin abusers' primary
purpose in life becomes seeking and using drugs. The drugs literally
change their brains.
Physical dependence develops with higher doses of the
drug. With physical dependence, the body adapts to the presence of
the drug and withdrawal symptoms occur if use is reduced abruptly.
Withdrawal may occur within a few hours after the last time the drug
is taken. Symptoms of withdrawal include restlessness, muscle and
bone pain, insomnia, diarrhea, vomiting, cold flashes with goose
bumps ("cold turkey"), and leg movements. Major withdrawal symptoms
peak between 24 and 48 hours after the last dose of heroin and
subside after about a week. However, some people have shown
persistent withdrawal signs for many months. Heroin withdrawal is
never fatal to otherwise healthy adults, but it can cause death to
the fetus of a pregnant addict.
At some point during continuous heroin use, a person
can become addicted to the drug. Sometimes addicted individuals will
endure many of the withdrawal symptoms to reduce their tolerance for
the drug so that they can again experience the
rush.
Physical dependence and the emergence of withdrawal
symptoms were once believed to be the key features of heroin
addiction. We now know this may not be the case entirely, since
craving and relapse can occur weeks and months after withdrawal
symptoms are long gone. We also know that patients with chronic pain
who need opiates to function (sometimes over extended periods) have
few if any problems leaving opiates after their pain is resolved by
other means. This may be because the patient in pain is simply
seeking relief of pain and not the rush sought by the addict.
Q) What are the medical complications of chronic
heroin addiction and use?
A) Medical consequences of chronic heroin abuse
include scarred and/or collapsed veins, bacterial infections of the
blood vessels and heart valves, abscesses (boils) and other
soft-tissue infections, and liver or kidney disease. Lung
complications (including various types of pneumonia and
tuberculosis) may result from the poor health condition of the
abuser as well as from heroin's depressing effects on respiration.
Many of the additives in street heroin may include substances that
do not readily dissolve and result in clogging the blood vessels
that lead to the lungs, liver, kidneys, or brain. This can cause
infection or even death of small patches of cells in vital organs.
Immune reactions to these or other contaminants can cause arthritis
or other rheumatologic problems.
One of the greatest risks of being a heroin addict is
death from heroin overdose. Each year about one percent of all
heroin addicts in the United States die from an overdose of heroin
despite having developed a fantastic tolerance to the effects of the
drug. In a non-tolerant person the estimated lethal dose of heroin
may range from 200 to 500 mg, but addicts have tolerated doses as
high as 1800 mg without even being sick[1].
Q) Are heroin users at special risk for contracting
HIV/AIDS and hepatitis B and C?
A) Because many heroin addicts often share needles and
other injection equipment, they are at special risk of contracting
HIV and other infectious diseases. Infection of injection drug users
with HIV is spread primarily through reuse of contaminated syringes
and needles or other paraphernalia by more than one person, as well
as through unprotected sexual intercourse with HIV-infected
individuals. For nearly one-third of Americans infected with HIV,
injection drug use is a risk factor. In fact, drug abuse is the
fastest growing vector for the spread of HIV in the
Nation.
Research has found that drug abusers can change the
behaviors that put them at risk for contracting HIV, through drug
abuse treatment, prevention, and community-based outreach programs.
They can eliminate drug use, drug-related risk behaviors such as
needle sharing, unsafe sexual practices, and, in turn, the risk of
exposure to HIV/AIDS and other infectious diseases. Drug abuse
prevention and treatment are highly effective in preventing the
spread of HIV.
Q) How does heroin abuse affect pregnant
women?
A) Heroin abuse can cause serious complications during
pregnancy, including miscarriage and premature delivery. Children
born to addicted mothers are at greater risk of SIDS (sudden infant
death syndrome), as well.
