IMPORTANT POINTS
|
|---|
- Heroin and opiates are not commonly abused by
adolescents, but the minority who do use these substances are considered
high-risk.
- Opiate overdose is readily treatable with attention to the
ABCs and administration of naloxone.
- Physiologic signs not only are
related to the specific drug but also to the mode of administration and
lifestyle of the substance user.
- Neonatal opiate withdrawal is
characterized by a readily recognizable set of symptoms and may be treated
with phenobarbital.
- Opiate withdrawal should be undertaken in
conjunction with treatment with methadone and behavioral therapy.

Definitions
|
|---|
Opiates are a diverse set of drugs that include both illicit
substances of abuse and prescription medications. Heroin is the prototype of
the opiate class. It is produced as a white crystal but may be adulterated
with lactose or procaine to achieve a concentration of 1 to 20 mg per dose.
Heroin is short-acting and highly addictive because of its rapid clearance
by the liver and usual mode of use, that is, by injection. Heroin is
excreted in urine as morphine.
Prescription opiates include morphine,
meperidine, codeine, oxycodone, and hydromorphone. Morphine and codeine are
derived from opium. Oxycodone and hydromorphone are semisynthetic opiates.
Meperidine and methadone are fully synthetic.
"Designer"
opiates are synthetic derivatives of opiates created in makeshift
laboratories that include 3-methylfentanyl (meperidine and fentanyl) and
MPTP (1, methyl, 4 phenyl 1,2,3,6 tetrahydropyridine). The substances in
this group of opiates are always changing, not only because of variation in
laboratories, but also to evade law enforcement.

Epidemiology

|---|
The use of opiates by American high school and college students has decreased since
peaking in the early 1970s, when lifetime prevalence of heroin use in 12th
graders was greater than 2% and other opiates was 9%. In 1992, 1.2% of all
high school seniors had ever used heroin and 6% had used other . . . [Full Text of this Article]
