What
are the medical complications of chronic heroin use?
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.
Of course,
sharing of injection equipment or fluids can lead to some of the most
severe consequences of heroin abuse-infections with hepatitis B and
C, HIV, and a host of other blood-borne viruses, which drug abusers
can then pass on to their sexual partners and children.
How
does heroin abuse affect pregnant women?
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.
Pregnant women should not be detoxified from opiates because of the
increased risk of spontaneous abortion or premature delivery; rather,
treatment with methadone is strongly advised. Although infants born
to mothers taking prescribed methadone may show signs of physical
dependence, they can be treated easily and safely in the nursery.
Research has demonstrated also that the effects of in utero exposure
to methadone are relatively benign.
Why
are heroin users at special risk for contracting HIV/AIDS and hepatitis
B and C?
Heroin
addicts are at risk for contracting HIV, hepatitis C, and other infectious
diseases. Drug abusers may become infected with HIV, hepatitis C,
and other blood-borne pathogens through sharing and reuse of syringes
and injection paraphernalia that have been used by infected individuals.
They may also become infected with HIV and, although less often, to
hepatitis C through unprotected sexual contact with an infected person.
Injection drug use has been a factor in an estimated one-third of
all HIV and more than half of all hepatitis C cases in the Nation.
NIDA-funded 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.
What
are the opioid analogs and their dangers?
Drug
analogs are chemical compounds that are similar to other drugs in
their effects but differ slightly in their chemical structure. Some
analogs are produced by pharmaceutical companies for legitimate medical
reasons. Other analogs, sometimes referred to as "designer" drugs,
can be produced in illegal laboratories and are often more dangerous
and potent than the original drug. Two of the most commonly known
opioid analogs are fentanyl and meperidine (marketed under the brand
name Demerol, for example).
Fentanyl
was introduced in 1968 by a Belgian pharmaceutical company as a synthetic
narcotic to be used as an analgesic in surgical procedures because
of its minimal effects on the heart. Fentanyl is particularly dangerous
because it is 50 times more potent than heroin and can rapidly stop
respiration. This is not a problem during surgical procedures because
machines are used to help patients breathe. On the street, however,
users have been found dead with the needle used to inject the drug
still in their arms.
