Drug addiction is on the rise and is fast becoming a part of American culture. Deaths from drug overdoses have more than tripled since 1990. Additionally, people are becoming addicted at alarmingly younger ages. Drugs’ long term effects on the brain can be detrimental and even fatal.
That said, it’s important to remember that addiction treatment, including faith-based recovery for substance abuse, is becoming readily available across the country. Identifying when and how Americans are most likely to become addicted to drugs is the first step to preventing drug abuse.
People turn to drugs to find reprieve from their pain or to get a euphoric rush that cannot be found organically. While mental health, environmental influences, and many other factors can play a role in addiction, drugs can change the brain’s chemical composition and the way it functions.
To better understand these patterns of addiction, we must first cover how drugs affect the brain.

How the Brain Works
The brain is an intricate circuit of signals and responses that controls our actions, thoughts, and emotions. Neurotransmitters, the brain’s chemical messengers, send signals to distinct sections of the brain. In turn, neuroreceptors accept those signals, and they turn the signals into actions.
Think of the brain as a computer. Neurotransmitters are like the coding within the computer, telling it what functions to perform. Neuroreceptors, on the other hand, are what you see happening on the computer screen as a result of the coding.
In order to understand how drugs affect the brain, we need to dive into the specific parts that are affected. The cerebral cortex, limbic system, and brain stem all are significantly impacted by drugs.
- Cerebral cortex: Contains your sensory skills (eye sight, hearing and touch) and your motor skills (voluntary and involuntary movement). These areas function together to determine intellect, personality, and even what languages you can speak.
- Limbic system: Controls your emotions, memory, pleasure responses and learning ability. This is where your fight or flight responses are located. The limbic system is above your brainstem and beneath your cerebral cortex.
- Brain stem: Controls the body’s basic functions, such as sleeping, eating, heart rate, and breathing. The spinal cord is linked to the brain stem and helps the brain send and receive signals to the rest of your body. The brain and spinal cord make up your nervous system, so without this function, your brain will be unaware of what is happening in your body.
Each part of the brain controls an important aspect of our lives. These parts work together to translate what we are thinking and feeling into actions. Subsequently, brain damage can impair or even stop these functions by damaging key parts of the brain. When long term drug addiction is at play, the results can be catastrophic.
How Drugs Affect the Brain
Drugs work in the brain by interacting with bodily systems, lowering or increasing the production of brain chemicals, and altering perception. Drugs can speed up or slow down signals from the brain and assist with helping your body function when used correctly. Drug abuse, however, can lead to the numbing of nerve cells, which can make people reliant and addicted to drugs.
This reliance can lead to a substance use disorder. People with substance use disorder are often unable to function normally. In many cases, their everyday responsibilities become less of a priority, while their drug use becomes their primary concern.
Activities that garner natural rewards, such as eating food or accomplishing a goal, organically bring about pleasurable responses from your brain. On the other hand, drugs do this artificially. Once a chemical dependence has been established, addicts find themselves needing more and more of a drug to receive these positive responses from their brains. This is often the cause of drug overdoses.
Your brain’s reward system gets distorted when abusing drugs becomes a part of your daily routine. As long-term drug abuse continues, the pleasure received from natural rewards will lessen and reliance on drugs will worsen.
Each Drug Affects the Brain Differently
In short, which substance a person is addicted to will determine how their brain is affected by drugs. Here are some examples of how different drugs can target specific areas of the brain.
How Opiates and Opioids Affect the Brain
Opiates and opioids create bonds with naturally occurring opiate receptors in your brain. They mostly affect your brain stem function and the limbic system, which is why many people with addictions to opioids suffer from:
- Shallow breathing that is linked to respiratory failure
- Sleep deprivation and fatigue
- Lack of appetite and slowing of metabolism
- Increased heart rate
- Intense euphoric feelings
If you take opioids for a long time, it can actually change your brain chemicals to be reliant on the drugs. Your body may even be unable to have pleasure responses without these drugs. This ever-growing dependency often leads to opioid overdoses.
How Cocaine and Methamphetamine Affect the Brain
Cocaine and methamphetamine are stimulant drugs. They often target the limbic system and brain stem. For that reason, the side effects of include:
- Increased heart rate and body temperature
- Stunted appetite
- Increased alertness and adrenaline
- Short-lived pleasurable responses
A brief high from cocaine and methamphetamines ensures that people will continually use these drugs to keep feeling good. In the long term, this can seriously damage your cerebral cortex. In other words, these drugs can drastically change your personality, memory, and intelligence.
These examples show how drugs can affect the brain in different ways. They affect separate parts of the brain and connect to independent receptors. Both drugs also have short-term and long-term effects that can lead to brain damage and, in severe cases, death.
Other Factors that Cause Drug Addiction
There’s isn’t one factor that researchers have pinpointed as the catch-all influencer of drug addiction. However, some risk factors include:
- Genetics: Genetics can play a large role in substance abuse. Alcoholism and drug addiction can be passed on from generation to generation. Having someone in your life who has abused substances can increase your risk of abusing an addictive substance. An addictive personality, too, is a hereditary trait that can widely increase your risk of addiction.
- Environmental influences: Home and family life, friends, work, and traumatic events are all environmental factors that can induce drug abuse. Drastic environmental changes can also increase drug addiction rates. In some cases, adolescents (who go through many changes) turn to drugs as a means to cope.
- Psychological traits: How a person thinks, feels, and reacts to things can also increase their risk of becoming addicted to drugs. Character traits and mental health issues that encourage this type of behavior include impulsivity, stress, depression, and anxiety.
- Early use: Using drugs at a young age can increase the risks of developing an addiction. The earlier your body becomes reliant on drugs, the harder it is to recover and live a drug-free life.
