Is Addiction Genetic? What Science Says About Substance Abuse

-

Substance abuse is a sad reality of life, with around 29.5 million Americans 12 years and older affected. And as with many aspects of life, there may be a genetic element to substance abuse.

While this may seem strange to think about, it’s very possible. Is addiction genetic and can you still prevent your children from suffering from it? It’s a question best answered in detail and with nuance, so read on to find out more.

What Is Substance Abuse?

Substance abuse is the use of drugs or alcohol in excess. This use gets to the point of impairment or detriment to one’s physical and mental health. It often leads to addiction and can cause physical, emotional, and financial damage.

Substance abuse can involve any drug or alcohol, including legal and illegal substances. This includes prescription medications, over-the-counter drugs, alcohol, and street drugs. It can also involve the nonmedical use of prescription drugs.

The most common effects of substance abuse include changes in mood or behavior. People also experience impaired judgment, coordination, decision-making, and memory.

Substance abuse can also cause changes in the brain. This can lead to an increased risk of physical health problems. In some cases, substance abuse can be deadly, especially when involving illegal drugs.

What Is Addiction?

Addiction is a complex condition. It is a brain disease manifested by compulsive substance use despite harmful consequences. 

People with addiction have an intense focus on using a certain substance. They fixate on alcohol or drugs to the point that it takes over their life.

It can cause adverse psychological, physical, and social effects. And it can manifest because of a combination of environmental and genetic influences.

Treatment and recovery usually involve teamwork, with a multi-disciplinary team of health professionals. This includes physicians, therapists, psychologists, and social workers. Treatment options range from medications to therapy, among others.

Recovery is possible and can lead to profound life changes. This includes improved relationships, patience, and healthy lifestyle choices. It can even lead to the elimination of cravings and abstinence from the substances of abuse.

Is Addiction Genetic?

Scientific research suggests that addiction and genetics are related. Addiction can arise because of genetic factors. According to research, the genetic component of addiction can make a person more prone to addiction. But it does not doom them to it.

Addiction occurs when certain combinations of genes interact with the environment. These genes get triggered in a way that makes them more likely to develop an addiction. So a family history of addiction can be a predictor of an individual’s risk of addiction.

What is Epigenetics?

Epigenetics is an interesting new field of study. It examines how environmental factors and lifestyle choices may affect the transmission of genes.

Epigenetics could help explain why some people are more likely than others to become addicted to drugs. This is true even if no one in the family has ever used drugs.

An epigenetic study has shown that people’s DNA can be different in some ways. For instance, some hereditary factors are linked to a stronger desire for some drugs than for others.

They have also found that greater compulsiveness has genetic causes. They have also looked into why some people are more sensitive to the effects of a drug than others.

We need to do more study to figure out exactly what this means. But epigenetics can help us learn more about drug abuse and how to treat it.

What Role Does Heredity Play in Addiction?

Heredity plays an important role in alcohol and drug addiction. People can inherit genetic factors that increase the chances of developing an addiction.

Heredity can influence the likelihood and severity of addiction in various ways. This includes a preference for certain forms of substances, including alcohol. And people may be more susceptible to trigger addiction.

There can also be hereditary influences on the average individual’s severity of symptoms. This can relate to both addiction and medical conditions. This includes an increased condition for depression or anxiety.

Heredity also influences an individual’s response to certain treatments and therapies. Ultimately, the role of heredity in addiction is complex. And its importance should not be played down.

How Is Legacy Addiction Related to Genetic Addiction?

Legacy addiction is a form of genetic addiction passed down through the generations. As this happens, there is also a tendency for addiction to become stronger with each generation. In families with a history of addiction, the chances of developing an addiction increase.

Legacy addiction is an inherited vulnerability to certain substances. This includes an increased tolerance to alcohol. Or they may be a greater likelihood of becoming addicted to cigarettes.

It is important to know the signs of potential addiction and to seek help. Prevention is key when it comes to legacy addiction. So people need to understand that gene variations contribute to the risk of addiction.

What Genes Determine Risk of Addiction?

Scientists have identified many genes that determine the risk of addiction. Most of these are neurotransmitter genes thought to have an effect on the reward system in the brain.

For example, some genes relate to dopamine receptors. This help regulate the brain activity involved in experiencing pleasure.

Other genes may relate to serotonin. This is also involved in pleasure but is also involved in mood and emotions. These genes likely play a role in determining a person’s susceptibility to addiction. 

How Do Environmental Factors Affect Addiction?

Genes and heredity are not the only factors that affect addiction. Environmental factors greatly influence addiction. These influences can include home environment, socioeconomic status, peers, and even cultural influences.

An environment lacking stable relationships often leads to substance abuse. People growing up in unhealthy environments may turn to substances. They may use them to cope with difficult or painful situations in their life.

Those growing up in a disadvantaged environment are also more likely to develop an addiction. This is due to the availability of substances at a lower cost.

Finally, cultural influences, such as those passed down through generations are possible factors. They can play an influential role in the development of an addiction. 

What Are the Different Types of Addiction Treatment?

Addiction treatments range from cognitive-behavioral therapy and counseling to rehabilitative therapies. You can learn more about them on the list below:

Psychotherapy

Psychotherapy is effective for treating addiction. It involves exposing an individual to different strategies and techniques. The goal is to help an individual uncover underlying issues related to addiction.

Cognitive behavioral therapy is often used in psychotherapy for addiction. It focuses on teaching the individual how to respond more effectively to cravings.

Other forms of psychotherapy are mindfulness-based approaches, such as Dialectical Behavioral Therapy (DBT). This promotes awareness of thoughts and behavior. And it works by increasing a client’s ability to tolerate distress.

Step Programs

Addiction treatment often starts with spiritual and lifestyle changes. Step programs provide addicts a pathway to restore themselves to mental and physical health.

Each step encourages the individual to take responsibility for their behaviors and addiction. The steps often involve identifying what your higher power is and surrendering to it. Then you need to make amends to those that you have wronged.

Step programs provide addicts with a safe and supportive environment for recovery. Members can reach out and help one another.

Exercise, Nutrition, and Mindfulness

Exercise, nutrition, and mindfulness are all key elements of addiction treatment.

Exercise can help to manage some of the withdrawal symptoms associated with addiction. At the same time, it improves a person’s mood, confidence, and self-image.

Nutrition can provide essential needed to prevent deficiencies that can worsen symptoms. It can provide substances with nutritional value that help. This helps decrease a person’s cravings for alcohol and drugs.

Mindfulness can bring an element of control to those struggling with addiction. It allows one to better understand and address their behaviors and feelings. It can even help bring self-awareness and insight into reducing the urge to use substances.

Exercise, nutrition, and mindfulness create an integrated approach to treating addiction. They will reduce the risk of relapse and make an individual stronger in body and mind.

Medications

Medications are often used to assist in the treatment of addiction. These drugs can help with symptom relief, cravings, and detoxification. Antidepressants, opioids, and other drugs can help to reduce unwanted withdrawal symptoms.

But you should use medications with caution. This is because some may be habit-forming and may create a physical alcohol dependency. You need to get the facts first before you dive into medication-assisted recovery. 

Learning the Genetics of Addiction

Is addiction genetic? It depends on who you ask, but generally, a combination of genetic and environmental factors likely contributes to substance abuse.

All this points out the need for more research into the genetic and epigenetic mechanisms underlying addiction. And there should be a push for interventions. These should incorporate both genetic and environmental information into treatment approaches.

So if you or a loved one is struggling with addiction, what are you waiting for? Reach out to a health care or behavioral health care provider for help.
