The Modern Definition of Addiction and How it’s Changed

Our perspective and definition of addiction have changed wildly over the past 100 years. As our understanding of the psychology behind addiction and substance use disorder has evolved and expanded, so has our definition.

As of today, Merriam Webster defines addiction as “a compulsive, chronic, physiological or psychological need for a habit-forming substance, behavior or activity” that leads to harmful effects and “well-defined symptoms (such as anxiety, irritability, tremors, or nausea) upon withdrawal or abstinence.”

This definition of addiction is not just limited to alcohol or narcotics. Addiction comes in many forms, including chemical addictions to behavioral addictions.

Common Types of Addiction

Chemical Addictions

Chemical addiction reflects a dependency on substances like narcotics. These substances interact with the brain in potent craving-inducing manners that prompt the user to seek more. Not all people suffering from chemical addiction are considered addicts, like those who medically require dependency-causing treatments.1

Types of chemical addictions can include:

  • Alcohol
  • Nicotine
  • Tobacco
  • Opioids
  • Stimulants

Behavioral Addictions

While many are familiar with chemical dependency, it is just as easy (if not easier) to become addicted to certain behaviors. Behavioral addictions begin similarly to substance addictions – the person engages in an activity that stimulates them and makes them feel good. Once that activity ends, the individual goes through a cycle of emotional and psychological side effects that prompt them to seek out that activity again.1

Types of behavioral addictions can include:

  • Sex Addiction
  • Gambling Addiction
  • Eating Addiction
  • Internet Addiction
  • Video Game Addiction

Early Models of Addiction

Moral Model

As one of the earliest models of addiction, the Moral Model classified addiction as an indicator of one’s weak morality. This model positions addiction as an indication of deep flaws and character defects that ultimately cannot be fixed or helped. The Moral Model led to the development of social stigmas surrounding addiction.2

Temperance Model

The Temperance Model was born out of the Moral Model, but instead of blaming character flaws, it considers substances the cause of addiction. All it takes is a single encounter with a substance and an individual cannot help but become addicted.2

This perspective on addiction led to heavy involvement from the government in developing policies and regulations limiting access to substances deemed dangerous.

Characterological Model

The Characterological Model claims abnormal character defects are the root of the addiction. Unlike the Moral Model where addiction comes from weak character, the characterological model argues that some individuals are born with addictive personalities. These addictive personalities are accompanied by egocentricity, poor impulse-control, manipulative traits, low self-esteem, a need for power/control, and an inability to cope with stress.2

Educational Models

This model views addiction as resulting from learned behaviors and a lack of education. These learned behaviors stem from a combination of modeled behavior, cognitive processes, and genetic influences. This model prioritizes therapeutic techniques centered on identifying triggers, building new habits, and learning about the roots and effects of addiction.2

Modern View on Addiction

Today, we think of addiction like any other disease. Addiction is seen as a chronic illness that can be diagnosed, observed, and treated. This model recognizes that addiction stems from personal choice but ultimately grows out of control and sometimes needs assistance to get back under control.2

Past Addiction Treatment

Over the years, addiction treatment and preventative measures have evolved and adapted into the practices we hold in this day and age.3

Society’s Outlook on Addiction: From the Past to Present

In the beginning, we saw addiction and the need for addiction treatment as a personal failing or weakness, as something shameful that reflected personal defects.

Now, our understanding of addiction is entirely different. We tend to be more gracious in our understanding of addiction, though social stigmas still exist. Addiction can happen to anyone. It’s a disease that begins with a choice that ultimately turns into a habit that grows into an addiction.

Addiction Treatment in the Common Day

Today, addiction is highly treatable, and there are several paths available to you.

  • Detox: Most wellness clinics and rehabilitation centers begin with detox. While detox can feel daunting, working with a team of professionals can make your withdrawal process less stressful. 
  • Therapies: Therapy is a key component of achieving long-lasting sobriety, helping patients learn to identify triggering events, create new habits, and learn emotional coping tools to prevent relapse.
  • In-Patient/Out-patient Care: Depending on your needs, you can also opt to receive treatment while living at a rehabilitation center (in-patient care) or live at home and return for treatment (out-patient care.)

When it comes to daily life, additional support comes in many forms. Peer support groups, sober living housing programs, and medications (i.e. benzodiazepines, anticonvulsants, antidepressants, clonidine) all offer aid to people on the road to recovery.

If you’re struggling to find your way back to yourself, know you’re not alone. 

We at Brooks Healing Center are here for you and want to help you fall in love with everything life has to offer you. If you’re looking for some support on your road to recovery, reach out. We’re happy to discuss the pathway to recovery that works best for your lifestyle and goals.
