Heroin
Addiction 
Heroin addiction like all
opiate addictions occurs when heroin is administered over a sustained period
of time. The onset of heroin addiction can be both rapid and severe, dependent
on the amount used and frequency in a designated period of time. Heroin addicts
will "crave" more of the drug and experience withdrawal symptoms if
they do not get their regular "fix" or dose. Not all of the mechanisms
by which heroin and other opiates affect the brain are known. Likewise, the
exact brain mechanisms that cause tolerance and addiction are not completely
understood. Heroin stimulates a "pleasure system" in the brain. This
system involves neurons in the mid-brain that use the neurotransmitter called
"dopamine." These mid-brain dopamine neurons project to another structure
called the nucleus accumbens which then projects to the cerebral cortex. This
system is responsible for the pleasurable effects of heroin and for the addictive
power of the drug.
Like
other drug addictions, heroin can become the most important aspect of their
lives. Heroin addicts often have habits that cost $100-$200 a day, which can
cause addicts to quickly turn to lives of shoplifting, burglary, theft, drug
dealing, and prostitution to support their habits. Methadone is a drug that
has been used for several decades to treat heroin addiction by blocking heroins
effects. Methadone generally entails the entire spectrum of opioid side effects,
including the development of tolerance and physical and psychological dependence.
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 addiction to heroin is being experienced by 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 nationwide. 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.
