Addiction and Genetics: Is addiction hereditary?

Is Drug Addiction Genetic

Thinking of addiction as genetic begins with understanding that addiction is a chronic relapsing brain disorder. “In many ways, it’s no different than having a family history with heart disease or diabetes,” says Dr. Anand. They found that adopted children had a higher risk of drug addiction if their biological parents were addicted. Experts also found that an adopted child’s risk of drug addiction was higher if their biological parent had alcoholism, criminal convictions, or a severe psychiatric illness. Through epigenetics, experts can understand how genetic factors and lifestyle choices affect someone’s risk for addiction. In order for you to develop an addiction, you first have to experiment with drugs.

In these cases, parents may not have as much oversight or control of their child’s actions. Because of this, they may do riskier things, like drug use. Each person has a mix of gene variations that influence addiction. When scientists look for “addiction genes,” what they are really looking for are biological differences that may make a person more or less vulnerable to addiction. The genetic connection to addiction comes through inherited levels of dopamine, a neurotransmitter made in your brain. About half of your susceptibility to developing a substance use disorder (SUD) can be hereditary.

  2. Find out more about addictive personalities by reading our guide.
  3. They’ll develop differently, and that will change their individual risk for addiction.
  4. High levels of dopamine can fuel poor impulse control and tilt someone toward addictive behaviors.
  5. Anybody can develop an SUD, and they can do it for any number of reasons in their life.

Contact a treatment center today to start your journey to recovery. Finding the genes involved in addiction is a good first step in finding solutions. Understanding how genes cause biological differences can lead to improved treatments for substance use disorder. One big thing we’ve learned for sure—a huge variety of biological processes influence addiction risk! Every person inherits a unique combination of gene variations.

Genes Affect Your Risk for Addiction

Moreover, people who use drugs are facing an increasingly dangerous drug supply, now often tainted with fentanyl. Approximately 107,000 people died of drug overdoses in 2021, and 37% of these deaths involved simultaneous exposure to both opioids and stimulant drugs. Drug use and addiction represent a public health crisis, characterized by high social, emotional, and financial costs to families, communities, and society. That’s because there is an inherited component, meaning it can pass from parent to child by way of genes. For this reason, your family history offers clues about how vulnerable to addiction you might be. For example, if you have a close relative that’s affected, it’s a clue to be extra careful.

Is Drug Addiction Genetic

Experts believe that someday, they may be able to use a dopamine receptor, called D2, to tell if someone will become addicted to heroin, cocaine, or alcohol. Some brain imaging shows that people with fewer D2 receptors might be more likely to become addicted to drugs. Your ability to get drugs is important in the how long does it take to detox from alcohol timeline and more development of drug addictions. If you’re able to buy and use drugs easily, you’ll be more at risk for addiction. These will often include cognitive therapies that can help identify the route of addictive tendencies and help to develop methodologies and coping mechanisms for controlling urges and triggers.

Genetic Signature for Drug Addiction Revealed in New Analysis of More Than A Million Genomes

Clearly, your family tree isn’t the sole indicator of addiction risk. The world around you also can play a significant role in opening a door that leads to problematic substance use, notes Dr. Anand. Disease can be woven into your DNA — and that includes the disease of drug addiction. You may be more likely to abuse drugs if your peers sway you to do so.

Further, most clinical trials and behavioral studies have focused on individual substances, rather than addiction more broadly. As we understand more about how medication effects vary from person to person, genetic tests may inform treatment. Long-term, they may be used to predict which treatments are likely to be most effective based on an individual’s genetic profile. Gene therapies are also being developed to treat addiction.

Genetic predisposition vs rewiring the brain

No one is born destined to develop substance use disorder. Like most other diseases, it’s genes and environment together that determine the risk. If you have a harsh family situation or weak bonds with your siblings and parents, you may be at a higher risk for addiction.

In children aged 9 or 10 years without any experience of substance use, these genes correlated with parental substance use and externalizing behavior. Studies suggest that about half of a person’s risk of developing a drug addiction is based on their genetic makeup. This means that fda drug safety communication specific genes passed down in your family may put you at a higher risk for drug addiction. The interplay between genetic predisposition and the individual is commonly mistaken for the vague term “addictive personality”. In actuality, addictive personalities are far more complex.

The inclusion of data from different ancestral groups in this study cannot and should not be used to assign or categorize variable genetic risk for substance use disorder to specific populations. As genetic information is used to better understand human health and health inequities, expansive and inclusive data collection is essential. “Using genomics, we can create a data-driven pipeline to prioritize existing medications for further study and improve chances of discovering new treatments.

After repeated use of the drug, addiction becomes a possibility. From there on, your genetics are one thing that will determine how likely you are to actually become addicted. This is part of our basic survival instinct and means that addiction, or the potential for it, is hardwired into our brains. “Substance use disorders and mental disorders often co-occur, and we know that the most effective treatments help people address both issues at the same time.

Anybody can develop an SUD, and they can do it for any number of reasons in their life. “There’s no simple answer or explanation,” says Dr. Anand. But does that mean your chance of addiction is essentially a coin flip if you have a family history of SUD? It’s a little more complicated than that, says addiction psychiatrist Akhil Anand, MD. These areas may have limited access to things like adequate food and basic levels of safety. People in these areas are at risk for a lower quality of health.

While finding the precise genetic cause is tricky, multiple lines of research do show that genes influence substance use. From careful studies, scientists estimate a person’s genetics account for percent of their risk. Next, the researchers look for segments of chromosomes that are more common in affected people compared to unaffected. They narrow the segments down to specific genes to study further. Because people have complex and varied lives, in-depth studies are often done using animals in a controlled lab setting.

Research has shown that these disparities have a link to higher rates of substance misuse. Published today in Nature Mental Health, the study was led by researchers at the Washington john carter author at sober home University in St. Louis, along with more than 150 coauthors from around the world. The pedigrees (family trees) above show affected people in red and unaffected in white.
