Heroin is a central nervous system depressant sending signals to slow breathing and mask pain. It comes in a white powder form, small light brown rocks, or a black sticky substance. It can be snorted and smoked, but most commonly, it is injected. Injecting heroin comes with even more dangerous complications.

The short-term effects of heroin are usually extremely pleasurable, making the drug so addictive. These effects last for around 3-5 hours and may include the following:

  • intense pleasure and pain relief
  • reduced appetite, possible vomiting
  • clumsiness, drowsiness, confusion, and relaxation
  • slurred and slow speech
  • slowed breathing and heartbeat
  • dry mouth, small pupils
  • heavy feeling arms and legs
  • in and out of being semiconscious and conscious
  • intense itching.

Heroin causes huge amounts of dopamine to be released. This signals to the brain that something positive and important has occurred and needs to be repeated.

The most immediate and severe long-term effect of heroin is overdose, which often leads to death. The longer a person uses heroin, the higher the risk of overdose. This is because their consumption continuously increases in an effort to feel the same high/ and/or relief felt during their first use. Some other long-term complications that occur from heroin use are:

  • 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
  • dependence on heroin
  • financial, work, or social problems.

Prolonged and increased high doses of opioids change the brain so that it functions more or less normally when the drug is present and abnormally when the drug is removed. That is why it is said a person with opioid addiction uses the drug in order to feel ‘normal’. This alteration in brain functioning results in drug tolerance and dependence (hazeldonbettyford.com).

Intense sadness and depression are short and long-term side effects of continued heroin use. This in itself, causes the user to feel like they need to keep using to mask the negative feelings they have without the drug.

Despite common assumptions, most people experiencing opioid or heroin addiction can’t recall the last time their drug use was enjoyable. After a certain point, substance abuse and dependence become hard work, and the addictive cycle becomes its own form of torture.

suffering from the effects of withdraw

Withdrawal from heroin can be extremely uncomfortable, to say the least. A rehab program may significantly reduce the negative symptoms felt during withdrawal. 

Withdrawal starts anywhere from 6 to 24 hours from your last dose and can last up to a week, with days 1-3 being the worst.

These symptoms may include:

  • cravings for heroin
  • restlessness and irritability
  • depression and crying
  • diarrhea
  • restless sleep and yawning
  • stomach and leg cramps
  • vomiting and no appetite
  • goosebumps
  • runny nose
  • fast heartbeat.

Naloxone is a medicine that temporarily reverses the effects of opioid overdose, allowing a person to breathe and buying time for medical help to arrive. Naloxone is completely legal, safe, and easy to use.

The easiest form of administration is a nasal spray. If someone overdoses on heroin and another person is present or finds them, they can spray Naloxone into the overdosed person’s nose to temporarily revive them.

Currently in Victoria, to obtain Naloxone, you will need to get a prescription from a doctor and fill it at a pharmacy. It is definitely worth it to potentially save a loved one’s life.
