When an individual starts abusing drugs, heat doesn’t have the intention to become an addict. Yet, it is a voluntary act, but it is not in the hands of an individual to become an addict or remain an abuser. Why is this so? Because this is a disease, a brain disease in which an addict does not only get affected physically but neurologically as well. Willing Ways Lahore, the best addiction treatment center in Lahore, prioritizes providing treatment according to the mental condition of the patient; it is the brain’s different organs that can affect by the chemicals of drugs.

In this article, we will discuss the impact of top drugs on brain health and how an unhealthy brain affects the patient’s daily life.

Addiction Impacts on brain health:

  • Prefrontal cortex:

The prefrontal cortex is important to understand because some studies say that it causes to understand percodan addiction and same is a part of the brain located at the front of the brain and is considered an essential brain part as it operates all functions for planning expressions of emotions decision making and motivating social behavior. A typical function of the prefrontal cortex is executive functioning which is further described as the ability to differentiate between conflicting thoughts, good and bad, right and wrong, and future consequences of current activities. For people who become addicts, such as in the case of digital detox for smartphone addiction, their prefrontal cortex affects as badly as their physical organs. Their ability to make decisions,  their cognitions, and their ability to assess social behaviors get reduced day by day. They keep on making wrong decisions and taking drugs every day, which contribute to their addiction and make them vulnerable to life-threatening.

  • Hippocampus:

Hippocampus is a part of the brain which. Works for learning and memory, addiction challenges in daily life, whatever we see, listen, and do get stored in our brain through the hippocampus. 

It stores the whole of the information in the brain and helps the person to use that information when it is needed.

When we talk about addicts,  their brains are badly affected due to drugs, as we discussed earlier in this article. It comes observed in erects that their ability to store information reduces day by day. That is why they become unable to store and use the given and provided information at the time when needed. Bipolar disorder is also a brain disorder, and not only the ability to store information affects addicts,  but the ability to memorize situations, scenarios, events, reasoning, and other things. It produces more challenges for an addict. Addicts most after time face some short-term memory loss problems; it is due to the dysfunctional city of the hippocampus.

  • Limbic system:

The limbic system is responsible for emotions, motivation, and pleasure-seeking behaviors. It helps our person to sense and enjoy the moments. Also, it is responsible for making memories. It coordinates with the hippocampus for making memories and new learnings. If we talk about addicts’ brain, the use of the drug also affects their limbic system, which means their emotional regulation get affected negatively. This is the reason an addict has no control over their emotions. They expressed their emotions negatively and unhealthily. Not only emotions, but the limbic system also functions for pleasure-seeking behavior. In addition, the addict’s urges to seek pleasure gets higher and higher day by day, which indicates the dysfunctional city of the limbic system. 

Above- mentioned are a few organs of the brain that get highly affected by drug use. There are many others too. Here we are going to discuss chemical imbalancement due to drug addiction.

Chemical Imbalance due to Drug Addiction

Continued use of drugs not only affects the brain’s different organs but also imbalances the chemistry of the brain. Science verifies that the brain chemical environment of an addict’s brain becomes inconsistent and imbalanced due to chemical or substance dependency. Further, we are about to discuss the imbalancement of chemicals in an addict’s brain. 

According to Nida, neurotransmitters (also known as brain chemicals) get affected by drug abuse, and they do not only disturb the patient’s brain health but also their bodies and their behaviors as well. The chemicals which get affected by drugs are mentioned below.


Dopamine is a chemical that works for pleasure and happiness. In addition, the released amount of troponin gets affected and wakes only when the patient uses the substance. The substance increases the amount of dopamine in the brain. The brain becomes dysfunctional to release dopamine naturally. 


Serotonin is a ‘feel good’ chemical. It gets affected due to drug abuse. As a result, an addict remains unhappy, sleepless, low appetite, and uncomfortable. After quitting drugs, patients learn to feel good without taking any external substances.
