How long does it take to recover from addiction?
Alcohol and drugs affect the brain’s neurotransmitters and neural pathways. At the same time, the brain strives to maintain balance. As a result, when drugs and alcohol alter brain chemistry, the brain adapts. Once adaptation becomes the norm, the brain will want to “correct” the imbalance when the drug is no longer present by taking the drug again. Over time, substance use disorder changes both the structure of the brain and how it works.
The brain has billions of neurons that communicate via neural pathways. As children develop and learn, their brains create and change these pathways, a process known as neuroplasticity, with relative ease. By the age of about twenty-five, the brain has developed the majority of its neural pathways; Plasticity is significantly reduced.

The brain uses neural pathways as efficiently as possible, allowing repetitive tasks to become “automatic” or habitual. Repeated use of the same circuits embeds them deep into the brain, making changing their pathways more difficult. Imagine that you are pulling the blade of the scissors across the cardboard on the same line over and over again; The groove becomes more pronounced. Fortunately, the brain is more flexible than cardboard. Although adults need more time and effort to change neural pathways than a child does, adults can change their brains.
Altering the adult brain is essential for individuals who engage in addictive behaviors. Even in a high-tech society, humans still act according to the pleasure and reward system our early ancestors used to survive. The brain releases dopamine, the “feel-good” neurotransmitter when an action, event, or emotion is satisfying or pleasurable. To get more of that good feeling, humans repeat that stimulus or thought.

Alcohol and drugs affect the brain’s neurotransmitters and neural pathways. At the same time, the brain strives to maintain balance. As a result, when drugs and alcohol alter brain chemistry, the brain adapts. For example, the brain will reduce dopamine production if the drug artificially recreates the effects of dopamine. Once adaptation becomes the norm, the brain will want to “correct” the imbalance when the drug is no longer present by taking the drug again. Over time, substance use disorder (SUD) changes the structure of the brain and how it works.
This change in neural circuits is possible due to the neuroplasticity of the brain. Brain flexibility is impressive and necessary to bring about positive changes; Unfortunately, it can also adapt to form unhealthy habits, associations, and addictions. As stated in the National Geographic article “The Addict Brain,” “addiction reshapes neural circuits to place a higher value on cocaine, heroin, or gin, at the expense of other interests such as health, work, family, or life itself.” The longer an addiction persists, the more profound it becomes, altering neural pathways and making recovery more difficult.
Areas of the brain affected by substance abuse (how long does it take to recover from addiction)
While alcohol and drugs affect the entire brain, some areas are more associated with SUD than others. The National Institute on Drug Abuse (NIDA) explains the effects of drugs on the brain in an article titled “Drugs, Minds, and Behavior: The Science of Addiction,” which focuses on overstimulation of the three main brain regions: the basal ganglia, the extended amygdala and the prefrontal cortex.
The basal ganglia, which are connected to the brain’s reward system, learn about pleasurable activities such as enjoying a good meal or spending quality time with friends. When they are overstimulated by drug abuse, they lose sensitivity to natural neurotransmitters, such as dopamine. As drug abuse continues, the drugs become the only stimulus that activates this reward center.
The stretched amygdala is associated with negative emotions such as stress, anxiety, and irritability. These are the symptoms a person experiences when a substance leaves the bloodstream. To avoid negative withdrawal symptoms, individuals often take more medication, creating a feedback loop.
The prefrontal cortex is the area of the brain that controls decision-making, reasoning, problem-solving, self-control, and impulse control. When this area of the brain is affected by drugs, confusion and poor decisions take over the cognitive process.

Many drugs, including alcohol, affect the cerebellum. The cerebellum helps with muscle control and coordination, which is why people who have had a lot of drinks may stumble and spin when walking.
Excessive drinking also reduces the gray and white matter in the cortex, which slows down the growth and development of cells. The dura, the protective layers over the brain, also shrink due to dehydration.
Loss of minerals and nutrients due to excessive drinking, which the Centers for Disease Control and Prevention (CDC) defines as more than four drinks for women and five for men, can impair brain functioning, even after there is no alcohol in the bloodstream. Fortunately, abstaining from alcohol for a week showed an improvement in gray matter cell volume. However, white matter and other areas of the brain continue to recover months after the last drink.
Substances such as cocaine reduce blood flow to the brain, according to Treatment for Substance Abuse: Group Therapy at the National Center for Biotechnology Information. Once healed, it can take months for blood flow to return to normal or near-normal levels. For those who abuse cocaine, the frontal lobe is still showing signs of recovery 4 to 6 months after the last use.
What do brain scans show for addicted people? (How long does addiction last?)
Although addiction can manifest itself in many different ways, from physical changes to behavioral responses, brain imaging and scanning can also find signs of addiction in the brain itself.
Researchers studying how addiction alters the brain have found clear signs of addiction within brain chemistry and structure. Using technology such as magnetic resonance imaging (MRI) and positron emission tomography (PET), medical professionals can see the inner workings of the brain, both with and without addiction.
These scans show us that many different regions and pathways within the brain are affected by addiction. From increased neurotransmitters like dopamine to decreased or increased activity in certain areas of the brain, addiction has a direct impact on the structure, functioning, and health of the brain.

A 2009 study published in the journal Neuropharmacology used positron emission tomography (PET) scans to show the flow of dopamine to different areas of the brain in individuals who abused drugs. When the researchers followed dopamine through the brain, they found that dopamine levels were lower in parts of the brain that control repetitive behavior, risk-taking, and decision-making. Dopamine also affected areas of the brain that associate drug use with pleasure and motivation, increasing the likelihood that an individual would take drugs again.
A 2013 article published in JAMA Psychiatry noted that MRI scans can also show us how the brain responds to addictive stimuli, helping researchers understand why people with substance use disorders relapse after a period of sobriety. These scans showed that certain parts of the brain (particularly areas that can stimulate cravings) were highly active in individuals with substance use disorders when exposed to stimuli, increasing the likelihood that they would relapse.
Other studies have found that a series of brain pathways are involved in many different addictive activities, from getting drunk to developing chemical dependence on relapse. These pathways are particularly vulnerable to addictive substances and can become “rewired” to encourage individuals to continue using drugs.
Fortunately, brain scans are not only used to detect addiction-related abnormalities. Researchers, clinicians, and addiction specialists can use brain-scanning technology to identify areas of the brain that have changed due to addiction. From there, they can develop more personalized treatment plans that directly support these affected areas of the brain.
In this way, while brain scans can show us the harm caused by addiction, they can also point us toward possible proactive solutions to help individuals recover and find effective treatments for persistent addictive behavior.
Can the brain heal itself after addiction?
The brain is a wonderful organ, capable of incredible breakthroughs and life-changing thoughts and actions. However, due to its delicate structure and chemistry, the brain is also highly addictive.
Fortunately, researchers have found that brains damaged by addiction have the ability to “roll out” addictive behaviors, even though the risk of addiction never magically goes away.
Researchers have studied the many different ways the brain can adjust it back to the “basic” level during and after addiction treatment. A 2013 study published in the Journal of Psychology of Addictive Behaviors found that incorporating mindfulness and meditation in addiction treatment can reduce the risk of relapse. The study also suggests that the brain pathways that can lead to relapse may be retrained through mindfulness practice.

Another study published in the Journal of Neuroscience found that individuals who chronically used methamphetamine had fewer dopamine proteins than individuals who did not use the drug. As a result, methamphetamine users frequently experienced challenges with movement and memory and may have been more likely to develop Parkinson’s disease. The researchers found that 12 months of recovery resulted in an increase in the number of dopamine proteins (in some cases, an increase of up to 19%). These findings suggest that the brain can begin to heal itself in the wake of drug use.
Additional research is also beginning to reveal the structural changes that occur in the brain during addiction. Which can help scientists and medical professionals devise new treatment methods. A 2011 study published in the journal Alcoholism found that individuals who relapsed had less growth in the brain’s reward system. It is an area of the brain that controls pleasure and reward responses, compared to individuals who have not relapsed.
In addition to changes in the chemical processes and physical structure of the brain. Addiction recovery can help individuals develop new behaviors and routines that can help “retrain” the brain to face the new reality. Many reputable treatment programs use cognitive behavioral therapy (CBT) and other forms of therapy to help individuals learn how to create alternative actions and thought patterns that help the brain adapt.
Additionally, support from peers in recovery and trained clinicians can help individuals avoid common “triggers” of relapse in order to lessen their impact on the brain. This may include avoiding people, places, and situations associated with addictive behaviors. As well as finding new ways to manage troubled or difficult emotions or life circumstances.
Helping the brain recover from addiction
Research on brain recovery is limited and still relatively new. Less than a century ago, scientists believed that a mature brain stopped developing new cells. We now know that the brain continues to create new neural cells and pathways. However, recovery from addiction takes time, discipline, support, and patience. Before the brain can begin to heal, the body must be clean of any remaining matter. Detoxing can take anywhere from several days to several weeks, depending on the substance and how long the individual has been suffering from the addiction.
The brain will begin to regain lost gray matter volume within one week of the last drink with alcohol. Other areas of the brain and white matter in the prefrontal cortex take several months or longer to recover.
Rebuilding neural pathways to promote healthy choices and habits depends on each individual’s circumstances. Opiates and cocaine are highly addictive, making it even more difficult to recreate deeply ingrained neural circuits. In addition, the longer a substance is abused, the more solid the neural pathway becomes for that behavior.
Most medications alter dopamine levels. Several variables determine whether the brain’s ability to release and reabsorb dopamine will fully recover. In addition to the specific substance and duration of use. Dopamine recovery depends on a person’s age, genetics, mental health, and the number of medications that were used simultaneously.

Many medical professionals suggest ninety days as a general estimate of dopamine recovery. However, the damage from the drugs can last longer, requiring a year or more for dopamine levels and brain cells to recover. Some medications can permanently damage the receptors that reabsorb dopamine, preventing the brain from fully recovering.
The brain is a complex organ with billions of neurons that send messages to each other in order to maintain basic life functions. And coordinate muscle movement, learn new skills.
Neural pathways help build competence in repetitive tasks and behaviors. Which is positive for habits such as exercising, playing a musical instrument, or cooking a meal. However, this same efficiency can contribute to material dependence and make it difficult to overcome.
Fortunately, the brain has a strong neuroplasticity. It can rewire neural pathways to overcome self-destructive habits and behaviors and create pathways to healthy, sober life choices. With the support of healthcare professionals, friends and family, as well as patience and focus, the body and brain can recover from addiction.
