Heroin is a synthetic substance manufactured from the opium poppy plant. Initially, doctors prescribed this substance as a prescription painkiller, but the U.S. government outlawed heroin in the early 20th century because of its highly addictive nature. Heroin has a number of different psychological and physial effects that can be catastrophic to the body. Today we’re going to look at the man heroin effects on the brain. 

If you face such a situation, seek professional help from Renaissance Recovery Center before the drug destroys your brain health permanently that’s why it’s important to find a heroin addiction treatment program.

What Does Heroin Do to Your Brain?

Heroin has both short- and long-term effects on the brain. Besides physical dependence, chronic abuse of heroin leads to tolerance. As the brain adapts to the presence of the substance in the body, you will need higher doses to achieve similar effects.

Heroin Effects On The Brain

Among the most significant effects of heroin on your brain is the hindrance of the brain’s ability to produce natural dopamine. The receptors receive intense stimulation from ingested heroin, hindering the ability to provide the chemicals naturally. As a result, individuals can become entirely dependent on heroin to get dopamine and regulate pain. If you are in this phase and cut off heroin abruptly, severe withdrawal symptoms will manifest in a few hours — which can prove to be not only uncomfortable, but life-threatening.

Many chronic abusers of heroin suffer from long-term brain imbalance. Heroin addiction resulting from chronic use of the drug alters the brain’s physical structure, creating hormonal and neurological imbalances. You will continue to experience these imbalances even long after quitting the drug. Fortunately, a rehab facility can help you restore your health through a combination of medication-assisted and talk therapy programs.

Studies confirm that a deteriorating brain white matter caused by chronic heroin use is one of the severe side effects of heroin. In other words, heroin use reduces your reasoning and proper decision-making abilities. You may also have difficulties managing stress and regulating other impulsive behaviors, including engaging in illegal activities to acquire drugs.

Experts concur that continual exposure to heroin leads to the development of a body syndrome similar to dementia. The resultant protein build-up in the brain also leads to inflammations, and brain changes resembling the Alzheimer’s condition. As such, heroin affects the brain by causing severe cognitive impairment.

How Does Heroin Affect Cellular Communication in the Brain

Heroin binds to specific receptors in the body that releases neurotransmitters, dopamine, in the brain. Once released, these neurotransmitters regulate pain and cause feelings of happiness and even euphoria. 

Unfortunately, when released, the good feelings associated with the dopamine release reinforce the drug-taking behaviors. While the specific side effects and reinforcement of this behavior will depend on a number of factors including how much is used, how long it has been used, and more the end result is increased addiction potential and even changes in brain physiology.

Let’s take a closer look at the psychological effects of the drug and what heroin does to the brain.

How Addictive is Heroin?: Psychological Effects

When you wonder, “How addictive is heroin?” you may also be wondering about the reasons why. Heroin is so addictive that when you take it, it triggers an increase in dopamine production. In other words, it creates a pleasant rush that is almost impossible to ignore.

 When you first take heroin, it binds the opioid receptors in your brain. This binding releases unnaturally high levels of dopamine that your brain craves. The more you take heroin, the more your mind becomes dependant on the heroin to create dopamine. If you suddenly stop taking heroin, your brain suddenly has to revert to life without the dopamine rush. It struggles to cope and process this. One helpful way to imagine this is like a stretched rubber band. You keep pulling it back further and further, and suddenly you let go. If you’re holding the rubber band when you let go, you feel the sting of the snap. In the case of heroin, the sting is the heroin withdrawal symptoms, which may include: 

  • Muscle pain
  • Depression
  • Hallucinations
  • Insomnia
  • Nightmares

Let’s take a closer look at this.

Heroin Withdrawal Symptoms

Most of the people struggling with opiate use disorders have a long history of abusing several other substances, such as cocaine.

Furthermore, a large number of young people who abuse heroin in the U.S. also abuse other prescription opioids. In some cases, they may have begun using prescription opioids and then eventually graduate to using heroin.

The highly addictive nature and side effects of heroin on the brain result in overwhelming withdrawal symptoms when you attempt to quit. Some of the common signs include:

  • Nausea and vomiting
  • Abdominal pain
  • Tremors and physical agitation
  • Anxiety and depression
  • Muscle pains and twitches
  • Intense craving for the drug
