Drugs And Alcohol Effects On The Brain – With long-term alcohol or drug abuse, the brain physically changes. The brain actually shrinks and its ability to process information is impaired. When this happens, the areas of the brain that control impulse control, stress management and information processing can be damaged.
The limbic system is an important part of the brain that is affected by excessive alcohol or drug use. When a person drinks or takes drugs, the limbic system releases dopamine, a substance that makes us feel good.[/vc_column_text]
Drugs And Alcohol Effects On The Brain
With prolonged use, the brain adapts to the increase in dopamine and reduces the number of receptors that can process it. It also stops producing dopamine like it used to. As a result, the brain’s reward system receives very little input, and it becomes difficult for the individual to experience any form of pleasure. This is why many drug and alcohol abusers can be lifeless and depressed. They are no longer interested in the things that used to make them happy.
Long Term Health Effects Of Prolonged Drug And Alcohol Use
The limbic system is not the only part of the brain affected by chronic drug or alcohol abuse. The frontal lobe of the brain is also affected. It shrinks and loses its ability to function properly. This part of the brain controls judgment, choices, and the ability to distinguish between right and wrong. When the frontal lobe doesn’t work as it should, you can’t control the urge to drink or take drugs. The irony is that the part of the brain that you use to change your unhealthy habits has been damaged by those unhealthy habits and is unable to make good decisions.
The frontal lobe controls other parts of the brain, such as the amygdala. The amygdala is the emotional center of the brain. Without proper frontal lobe control, the amygdala becomes hypersensitive to stress. During this stage, one’s mood can fluctuate wildly and one can get stuck in a state of panic and worry. Many addicts and alcoholics are constantly afraid and rarely feel safe. Because the amygdala is overstimulated.
Excessive alcohol and drug use affects the cellular structure of the brain. We have all heard that drug abuse destroys brain cells. The brain consists of gray cells and white cells or fibers. Gray cells control thoughts and emotions while white cells provide connections and communication between gray cells. They are like network cables that send information from one gray cell to another. Chronic drug and alcohol use has been shown to destroy white blood cells in the brain. It breaks down the lines of communication so that information is not conveyed properly. The brain can use the remaining white blood cells to reroute these communication pathways, but this requires patience and time.
These negative effects of drugs and alcohol on the brain are frightening. But there is good news. If one can completely stop drinking or taking drugs, the brain begins to heal. With long-term abstinence, cognitive function and brain shrinkage can be reversed, new pathways can be formed in the brain, and a person can return to normal brain function. If a person can learn to live without drugs or alcohol, there is hope for full physical recovery. Do you have a glass of wine every now and then? you are not alone More than 85% of adults report drinking alcohol at some point. In 2020, alcohol consumption increased in the US, with the prevalence of heavy drinking among women increasing by 41%.
Long Term Effects Of Drug Addiction
Although occasional drinking is unlikely to cause health problems, moderate or heavy drinking can affect the brain. And, alcohol abuse can lead to deficits over time.
Alcohol affects your body quickly. It is absorbed through the lining of your stomach into your bloodstream. Once there, it spreads to tissues throughout your body. Alcohol reaches your brain in just five minutes and begins to affect you within 10 minutes.
After 20 minutes, your liver begins to process the alcohol. On average, the liver can metabolize 1 ounce of alcohol per hour. A blood alcohol level of 0.08, the legal drinking limit, takes about five and a half hours to leave your system. Alcohol stays in urine for up to 80 hours and in hair follicles for up to three months.
“Intoxication occurs when alcohol consumption exceeds your body’s ability to metabolize and break down alcohol,” says Jeffrey T. Johnson, DO, a Northwestern Medicine Regional Medical Group board-certified addiction specialist.
Alcohol Leads To More Violence Than Other Drugs, But You’d Never Know From The Headlines
Your whole body absorbs alcohol, but it really affects the brain. Alcohol disrupts the brain’s communication pathways. It can also affect how your brain processes information.
Your impaired vision while drinking alcohol can make you feel like you can drive no matter what your BAC is. Drivers with a BAC of 0.08 or higher are 11 times more likely to die in a single-vehicle crash than non-drinking drivers. Some states have higher penalties for people driving with a high BAC (0.15 to 0.20 or higher) because of the increased risk of fatal accidents.
Your body’s response to alcohol depends on many factors. These include your age, gender, overall health, how much you drink, how long you’ve been drinking and how often you normally drink.
Over time, heavy drinking can lead to mental health problems, such as depression and anxiety. Alcohol abuse can increase the risk of certain cancers as well as serious and potentially permanent brain damage. This can lead to Wernicke-Korsakoff syndrome (WKS), which is marked by dementia, extreme confusion and vision problems. WKS is a brain disorder caused by thiamine deficiency or vitamin B-1 deficiency. Taking certain vitamins and magnesium along with not drinking alcohol may improve your symptoms.
Alcohol Related Brain Damage
Alcohol can harm your body in many ways. The good news is that within a year of stopping drinking, most cognitive damage can be reversed or improved.

The human brain is incredibly complex. Researchers have studied it for centuries, but they still don’t fully understand how it works. One aspect of the brain’s complexity is how it develops.
From the time a child is conceived, the brain begins to grow, becoming more and more complex over time. It takes many years for the brain to fully develop. In fact, our brain doesn’t stop developing until we reach our twenties.
Because of the complexity of the brain and its primary role in a young person’s health, it’s important for them to get enough sleep, eat nutritious food, and seek medical attention for any potential trauma, such as a head injury.
Effects Of Alcohol On The Body
It’s also important for young people to avoid substance abuse – drugs and alcohol dramatically disrupt brain development and can cause long-term damage. In some cases, the results are irreversible.
Adolescence is an important stage in brain development. During these years, teenagers’ personalities are emerging—effectively growing into who they will be for the rest of their lives. Teenagers are also learning many new skills and developing the abilities they need to become well-adjusted, responsible adults.
Adolescent brains are adaptable to all kinds of experiences, and it’s easier for them to learn new things at this stage than adults. But this makes them more motivated to use mind-altering substances – and consequently more vulnerable to sustaining harm.
One aspect of the complexity of a healthy brain is the delicate balance of chemicals that keep the body and mind functioning normally. These chemicals are called neurotransmitters, and they carry messages between nerve cells and neurons, or nerve endings.
Alcohol And Cannabis Use And The Developing Brain
Neurotransmitters influence everything a person thinks and feels—including their mood, energy levels, consciousness, memory, ability to experience pleasure, and need for food and rest—so it’s important to keep your child’s brain healthy as it grows.
Overall, these chemicals help you stay healthy and feel better for whatever experiences you face. When you’re in danger, your brain is supposed to scare you and energize you—the “fight or flight” response.
When you’re with friends, your brain chemicals should help you feel a sense of comfort and trust. When your body needs food, your brain should make you hungry. And when your body needs rest, your brain should help you feel tired and ready for sleep.
Collectively, these brain chemicals are designed to help you take care of yourself—eating right, sleeping well, and building social relationships. Your brain chemicals, when working properly, motivate you to do the things necessary for your survival and happiness.
Mind Matters: Drugs And The Brain
The human brain is made up of cells called neurons. These cells are protected by a substance called myelin, which acts as a sort of insulator for messages to your brain. The older you are, the more “insulated” you are from the brain’s messages – that is, the better you can handle them.
But in teenagers, the protective properties of
