What is heroin?

Heroin is a depressant drug, which means it slows down the messages travelling between your brain and body. Heroin belongs to a group of drugs known as opioids that are from the opium poppy.1

Heroin comes in different forms, including:

  • Fine white powder
  • Coarse off-white granules
  • Tiny pieces of light brown ‘rock’1

Other names

Smack, gear, hammer, the dragon, H, dope, junk, harry, horse, black tar, white dynamite, homebake, china white, Chinese H, poison, Dr Harry1

How is it used?

Heroin is usually injected into a vein, but it’s also smoked (‘chasing the dragon’), and added to cigarettes and cannabis. The effects are usually felt straight away. The effects take around 10 to 15 minutes if snorted.2

Effects of heroin

There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

Heroin affects everyone differently, based on:

  • The person’s size, weight and health
  • Whether the person is used to taking it
  • Whether other drugs are taken around the same time
  • The amount taken
  • The strength of the drug (it varies from batch to batch)

You will experience the below effects, which will last for 3 to 5 hours:

  • Intense pleasure and pain relief
  • Relaxation, drowsiness and clumsiness
  • Confusion
  • Slurred and slow speech
  • Slow breathing and heartbeat
  • Dry mouth
  • Tiny pupils
  • Reduced appetite and vomiting
  • Decreased sex drive1,2

Injecting heroin and sharing needles may also cause:

  • Tetanus
  • Hepatitis B
  • Hepatitis C
  • HIV and AIDS1,2

Overdose

If you take a large amount or have a strong batch, you could overdose. If you have any of the symptoms below, call an ambulance straight away by dialling triple zero (000). Ambulance officers don’t need to involve the police.

  • Trouble concentrating
  • Falling asleep (‘going on the nod’)
  • Wanting to urinate but finding it hard to
  • Itchiness
  • Irregular heartbeat
  • Cold, clammy skin
  • Slow breathing, blue lips and fingertips
  • Passing out
  • Death1,2

Naloxone (also known as Narcan®) reverses the effects of heroin, particularly in the case of an overdose.

In the days after heroin use, the following may be experienced:

  • Irritability
  • Depression1,2

Long-term effects

Regular use of heroin may eventually cause:

  • Intense sadness
  • Irregular periods and difficulty having children
  • No sex drive
  • Constipation
  • Damaged heart, lungs, liver and brain
  • Vein damage and skin, heart and lung infections from injecting
  • Needing to use more to get the same effect
  • Dependence on heroin

Using heroin with other drugs

The effects of taking heroin with other drugs – including over-the-counter or prescribed medications – can be unpredictable and dangerous, and could cause:

Withdrawal

Giving up heroin after using it for a long time is challenging because the body has to get used to functioning without it. Withdrawal symptoms usually start within 6 to 24 hours after the last dose and can last for about a week – days 1 to 3 will be the worst. These symptoms can include:

  • Cravings for heroin
  • Restlessness and irritability
  • Depression and crying
  • Diarrhoea
  • Restless sleep and yawning
  • Stomach and leg cramps
  • Vomiting and no appetite
  • Goosebumps
  • Runny nose
  • Fast heartbeat1,2

Getting help

If your use of heroin is affecting your health, family, relationships, work, school, financial or other life situations, you can find help and support.

There are many avenues for treatment of heroin dependence, including methadone, naltrexone, and buprenorphine.

Heroin and the law

Federal and state laws provide penalties for possessing, using, making or selling heroin, or driving under the influence.
