Heroin Facts

  • Intravenous injection of heroin provides the greatest intensity and most rapid onset of euphoria (7 to 8 seconds), while intramuscular injection of heroin produces a relatively slow onset of euphoria (5 to 8 minutes).
  • 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.
  • Heroin is typically sold as a white or brownish powder or as the black sticky substance known on the streets as "black tar heroin."
  • 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

Heroin Overdose

Heroin OverdoseHeroin works on the central nervous system. The abusers heartbeat slows as well as their breathing. They may loose consciousness. Any of these effects can be fatal if the dose is too high. Depending on purity and the user, a lethal dose of heroin may range from 200 to 500mg, but hardened addicts have survived doses of 1800mg and over. However, with street heroin there is no absolutely certain "safe dosage". It depends on tolerance, amount and purity taken. Overdose can occur when a dose taken is greater than that you're used to. A tolerable dose for an addict could be fatal to a first-time user. Tolerance to heroin in particular is quickly acquired. Even occasional weekend users need to take more to get the same effect over time. Tolerance can drop. Some users have overdosed on their 'regular dose', after just a few week's break.

  • muscle spasticity
  • slow and labored breathing
  • shallow breathing
  • stopped breathing (sometimes fatal within 2-4 hours)
