Cannabis-Induced Hypodopaminergic Anhedonia and Cognitive Decline in Humans: Embracing Putative Induction of Dopamine Homeostasis

Tobacco, heroin, cocaine, alcohol, cannabis and benzodiazepines are all substances that you can develop tolerance and dependence to. The importance of dopamine is a critical, as a neurotransmitter, it is the main reward system chemical in our brain. Dopamine rewards our brain for completing small tasks, receiving a grade on an exam, thinking of a good memory, sex, and many other pleasurable experiences. Dopamine is also important as it can help with increasing mood, motivation, and attention.

Just as neuroplasticity, your brain’s ability to adapt, played a part in your growing addiction, it fulfills a much more positive role in your recovery. It can help your brain chemistry normalize and modify your addiction-related behaviors. Therapeutic interventions like cognitive behavioral therapy (CBT) can guide this natural adaptivity towards new behaviors and thinking patterns focused on abstinence. One study using magnetic resonance imaging showed that dopamine transporter levels returned to near-normal levels after 14 months of abstinence. The study looked at the brains of those who abused methamphetamines, but more research is needed on other drugs and alcohol.

Obviously, the time it takes for the brain to recover depends on the severity of the damage done. The more intense or frequent the alcohol bouts are, the longer it will take the brain’s chemistry to return to normal levels. There is no hard and fast rule for how long it takes to get back into balance. The impact of alcohol on the brains of young people is particularly serious. Behavioral and cognitive problems including learning difficulties, memory issues, and decreased IQ can develop because of alcohol use. Alcoholism also causes other harmful metabolic changes that can create mental impairments.

  • For the literature search, Pubmed, Ovid Medline, and Web of Science databases were used.

How Long Does the Brain Take to Heal After Quitting Alcohol?

While activation in adolescents increases in the inferior parietal gyrus and putamen compared to healthy controls (13). Research suggests that functional alterations in these areas are neuroadaptive changes in cannabis users and may be compensatory (13). Instead, healthcare providers rely on a thorough evaluation of your medical history and behaviors surrounding substance use. They may order drug tests and evaluate prescription drug monitoring program reports.

Getting enough sleep is essential for overall brain health and can help promote healing after drug-induced damage. Aim for at least seven to eight hours of sleep each night to give your brain the time it needs to repair itself. Withdrawal symptoms can vary depending on the type of drug used and how long it was used for. For example, alcohol withdrawal can cause seizures and delirium tremens (DTs), which is a potentially life-threatening condition that causes severe confusion, high fever, and rapid heartbeat. Chronic drug use or abuse can cause irreversible changes in the brain’s structure and function, making it difficult for individuals to recover completely.

Why Does Drug Abuse Damage Our Brains?

For an adult, a divorce, loss of a job or death of a loved one may increase the risk of substance use. For a teenager, moving, family alcohol and dopamine divorce or changing schools can increase their risk. Medications can help modify your brain chemistry to help treat certain SUDs.

Like other chronic diseases such as heart disease or asthma, treatment for drug addiction usually isn’t a cure. Treatment enables people to counteract addiction’s disruptive effects on their brain and behavior and regain control of their lives. This learned “reflex” can last a long time, even in people who haven’t used drugs in many years.

As the name suggests, this is the stage that comes right after acute withdrawal. It’s also called protracted withdrawal, and it involves a series of severe, persistent symptoms that last even after the addiction is over. However, this is a crucial stage that all people with substance use disorders go through in their early stages of withdrawal.

Repeated substance use often causes people to lose interest in activities and experiences they once found pleasurable prior to substance use.

how long does it take to restore dopamine after alcohol and marijuana abuse

Damaged dopamine receptors can lead to the inability to feel pleasure from typical activities, which may deepen your dependence on the drug. Damaged receptors can also lead to depression and a condition called anhedonia, which causes you to be unable to feel pleasure. However, these conditions are often temporary, as long as substance use issues are addressed.

Early intervention can make a significant difference in outcomes for recovery and increase the chances of reversing any potential harm done to the brain. Additionally, some drugs are more damaging than others and may cause more severe and long-lasting effects on the brain. For example, methamphetamine use has been shown to cause significant damage to dopamine receptors in the brain that may not be reversible even after an individual stops using the drug.

  • Total sleep time during abstinence is reduced in chronic cocaine users [147] but appears to be at its greatest sometime in the early abstinence period (first week of abstinence) in laboratory studies including cocaine self-administration [148].
  • When we’re repeatedly exposed to pleasure-producing stimuli — social media, sugar, alcohol or any number of readily-available substances — our bodies adjust.
  • Dopamine is just one of many neurotransmitters that controls communication in the brain.
  • Most recovery after abstinence from alcohol is related to short- and long-term memory, and verbal skills.
  • They understand that one-size-does-not-fit-all” and will cater treatments to specific mental health and addiction needs.
  • An illicit drug can artificially flood the brain with the neurotransmitter dopamine, the brain reduces dopamine production in response.
