Heroin Drug Facts
Heroin is an addictive drug, and its use is a serious problem in America. Recent
studies suggest a shift from injecting heroin to snorting or smoking because of increased purity and the misconception that
these forms are safer.
Heroin is processed from morphine, a naturally occurring substance extracted from the seedpod
of the Asian poppy plant. Heroin usually appears as a white or brown powder. Street names for heroin include "smack," "H,"
"skag," and "junk." Other names may refer to types of heroin produced in a specific geographical area, such as "Mexican black
tar."
Health Hazards
Heroin abuse is associated with serious health conditions, including fatal overdose,
spontaneous abortion, collapsed veins, and, particularly in users who inject the drug, infectious diseases, including HIV/AIDS
and hepatitis.
The short-term effects of heroin abuse appear soon after a single dose and disappear in a few hours.
After an injection of heroin, the user reports feeling a surge of euphoria ("rush") accompanied by a warm flushing of the
skin, a dry mouth, and heavy extremities. Following this initial euphoria, the user goes "on the nod," an alternately wakeful
and drowsy state. Mental functioning becomes clouded due to the depression of the central nervous system. Long-term effects
of heroin appear after repeated use for some period of time. Chronic users may develop collapsed veins, infection of the heart
lining and valves, abscesses, cellulitis, and liver disease. Pulmonary complications, including various types of pneumonia,
may result from the poor health condition of the abuser, as well as from heroin’s depressing effects on respiration.
Heroin
abuse during pregnancy and its many associated environmental factors (e.g., lack of prenatal care) have been associated with
adverse consequences including low birth weight, an important risk factor for later developmental delay.
In addition
to the effects of the drug itself, street heroin may have additives 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.
The Drug Abuse Warning Network* lists heroin/morphine among the four most frequently
mentioned drugs reported in drug-related death cases in 2002. Nationwide, heroin emergency department mentions were statistically
unchanged from 2001 to 2002, but have increased 35 percent since 1995.
Tolerance, Addiction, and Withdrawal
With regular heroin use, tolerance develops. This means the abuser must use more
heroin to achieve the same intensity of effect. As higher doses are used over time, physical dependence and addiction develop.
With physical dependence, the body has adapted to the presence of the drug and withdrawal symptoms may occur if use is reduced
or stopped.
Withdrawal, which in regular abusers may occur as early as a few hours after the last administration, produces
drug craving, restlessness, muscle and bone pain, insomnia, diarrhea and vomiting, cold flashes with goose bumps ("cold turkey"),
kicking movements ("kicking the habit"), and other symptoms. Major withdrawal symptoms peak between 48 and 72 hours after
the last dose and subside after about a week. Sudden withdrawal by heavily dependent users who are in poor health is occasionally
fatal, although heroin withdrawal is considered less dangerous than alcohol or barbiturate withdrawal.
Treatment
There is a broad range of treatment options for heroin addiction, including medications
as well as behavioral therapies. Science has taught us that when medication treatment is integrated with other supportive
services, patients are often able to stop heroin (or other opiate) use and return to more stable and productive lives.
In
November 1997, the National Institutes of Health (NIH) convened a Consensus Panel on Effective Medical Treatment of Heroin
Addiction. The panel of national experts concluded that opiate drug addictions are diseases of the brain and medical disorders
that indeed can be treated effectively. The panel strongly recommended (1) broader access to methadone maintenance treatment
programs for people who are addicted to heroin or other opiate drugs; and (2) the Federal and State regulations and other
barriers impeding this access be eliminated. This panel also stressed the importance of providing substance abuse counseling,
psychosocial therapies, and other supportive services to enhance retention and successful outcomes in methadone maintenance
treatment programs. The panel’s full consensus statement is available by calling 1-888-NIH-CONSENSUS (1-888-644-2667)
or by visiting the NIH Consensus Development Program Web site at consensus.nih.gov.
Methadone, a synthetic opiate medication that blocks the effects of heroin for
about 24 hours, has a proven record of success when prescribed at a high enough dosage level for people addicted to heroin.
Other approved medications are naloxone, which is used to treat cases of overdose, and naltrexone, both of which
block the effects of morphine, heroin, and other opiates.
For the pregnant heroin abuser, methadone maintenance combined
with prenatal care and a comprehensive drug treatment program can improve many of the detrimental maternal and neonatal outcomes
associated with untreated heroin abuse. There is preliminary evidence that buprenorphine also is safe and effective
in treating heroin dependence during pregnancy, although infants exposed to methadone or buprenorphine during pregnancy typically
require treatment for withdrawal symptoms. For women who do not want or are not able to receive pharmacotherapy for their
heroin addiction, detoxification from opiates during pregnancy can be accomplished with relative safety, although the likelihood
of relapse to heroin use should be considered.
Buprenorphine is a recent addition to the array of medications now available
for treating addiction to heroin and other opiates. This medication is different from methadone in that it offers less risk
of addiction and can be dispensed in the privacy of a doctor’s office. Several other medications for use in heroin treatment
programs are also under study.
There are many effective behavioral treatments available for heroin addiction. These
can include residential and outpatient approaches. Several new behavioral therapies are showing particular promise for heroin
addiction. Contingency management therapy uses a voucher-based system, where patients earn "points" based on negative
drug tests, which they can exchange for items that encourage healthful living. Cognitive-behavioral interventions are
designed to help modify the patient’s thinking, expectancies, and behaviors and to increase skills in coping with various
life stressors.
