Heroin Intoxication:
Heroin Intoxication - epidemiology
(The 5-Minute Pediatric Consult)
- Neonatal:
- Fetal exposure commonly involves polysubstance abuse.
- 60–80% of heroin-exposed infants develop withdrawal—dependent on maternal dosing and length of use.
- Adolescents:
- Use peaked among US adolescents in the 1970s and then declined.
- Use is increasing again because a more pure product allows for smoking or snorting as well as injecting.
- Most use experimentally or intermittently; few become addicted and use daily.
- Use of opioid analgesics has increased dramatically over the last 10 years, and has become more common than heroin use.
- Overdose:
- Up to 1/3 of heroin users experience nonfatal overdose.
- Most occur in the home and with other people present.
- Risk factors include length of injecting history and concurrent use of CNS depressants.
- Deaths:
- Most heroin deaths occur when drug administered IV.
- Most deaths in patients in their late 20s or 30s, with significant drug dependence
- Multiple drug use common in heroin-related death
- Many deaths occur in people with a history of a nonfatal overdose.
Heroin Intoxication - incidence
- Statistically significant increase in new heroin use since 1992
- 141,000 new users in 1995
- Mean age of 1st use in 1995 = 19.3
Heroin Intoxication - prevalence
- Precise estimates of prevalence of use difficult
- ~2.9 million people used at least once
- ~633,000 used in last year
- Prevalence of fetal exposure <1–3.7%

About prevalence and incidence statistics:
The term 'prevalence' of Marijuana abuse usually refers to the estimated population
of people who are managing Marijuana abuse at any given time.
The term 'incidence' of Marijuana abuse refers to the annual diagnosis rate,
or the number of new cases of Marijuana abuse diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
