Substance Use Disorder vs Addiction: Key Differences Explained

One of the most frequently asked questions when unhealthy habits are becoming evident with alcohol or drugs is substance use disorder, and addiction, what is the difference? The two are different and a large number of people who become addicted also suffer from Substance Use Disorder (SUD). Knowing the difference may lead to signs of problems being detected earlier, to receiving the appropriate support and to making recovery choices. WellMind Therapy Center is aware that knowledge and understanding is one of the first steps towards healing and it is important for people to understand these differences so as to decrease the stigma and prompt them to seek professional help.

Key Takeaways

Substance Use Disorder (SUD) is a medical condition, diagnosed by mental health professionals.
A person’s addiction is generally defined as an out-of-control use of drugs or alcohol despite any negative consequences.
People can suffer from mild, moderate or severe SUD.
Prompt identification results in better recovery.
There are professional therapy, counselling, medication and support programs which can help people recover.
Personalized care and support can allow for recovery.

What is Substance Use Disorder (SUD)?

Substance use disorder (SUD) is a medical diagnosis (or mental health problem) in which someone has a problem controlling their use of alcohol, prescription medicine, or illegal drug. It is defined by some criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which measure the substance’s effect on a person’s functioning.

Person with a Substance Use Disorder uses drugs/alcohol despite having a problem in any area of life – work, school, relationships, body.

SUD is a continuum:

Mild
Moderate
Severe

Severity will be determined by the number of criteria that are met.

The following are common substances related to SUD:

Alcohol
Opioids
Prescription pain medications
Cocaine
Methamphetamine
Cannabis
Nicotine
Sedatives

SUD is not a moral failing or lack of will power. It’s a complex condition that’s affected by genetic, environmental, mental health, trauma and brain chemistry factors.

What is Addiction?

Addictive drug use is frequently called addiction which is defined as the persistent and compulsive use of drugs and alcohol despite the negative consequences of that drug use.

Addiction is a common term but rather than being diagnosed as “addiction,” a health care provider might diagnose what is called a Substance Use Disorder.

Those who have an addiction to a substance or activity are likely to:

Don’t feel like you can stop using a substance.
Experience intense cravings.
Take a lot of time to acquire or consume substances.
Continue to use even if health, financial or relationship problems arise.
Develop tolerance.
Experience withdrawal symptoms.

The brain’s reward system is affected by addiction, which makes it more challenging and more necessary to have professional help to control the use of a substance.

While many individuals who suffer from SUD are also addicts, this is not the same thing.

Substance Use Disorder vs. Addiction: What Is the Difference?

The difference between these two ideas is easier to understand when contrasted to each other: Understanding Substance Use Disorder and Addiction.

Substance Use Disorder	Addiction
A medical diagnosis	A commonly used descriptive term
Diagnosed using DSM-5 criteria	Describes compulsive behavior
Can be mild, moderate, or severe	Often refers to more severe substance problems
Includes different levels of severity	Usually indicates loss of control
Used by healthcare professionals	Commonly used by the general public

Key Differences

Medical Diagnosis

The National Native Addictions Partnership, the leading national nonprofit organization, states that SUD is a medical diagnosis by qualified health care providers.

Severity Levels

Other people with SUD may not have severe symptoms. Others can have mild to moderate SUDs and be responsive to early intervention.

Addiction Represents Severe Patterns

Addiction is usually defined as frequent and excessive drug use with a high level of difficulty in stopping use.

Focus on Function

The assessment of substance use and functioning is carried out rather than focusing on frequency of use.

Understanding the Stages of Substance Use Disorder

Treatment may take a lot of time to build up—usually not a sudden occurrence—due to SUDs.

1. Experimentation

An individual experiences alcohol or drugs as a curiosity or by peer influence.

2. Regular Use

It starts becoming more common to use substances, for instance, on weekends or during stressful times.

3. Risky Use

Some person begins to experience the effects of use, but continues to use.

Examples include:

Missing work
Driving while intoxicated.Impaired driving.
Family conflicts
Financial problems

4. Dependence

Body becomes accustomed to the substance.

Signs include:

Tolerance
Withdrawal symptoms
Uses more of the substance

5. Severe Substance Use Disorder

Negative substances affect an individual’s life and they are present 24 hours in a day.

At this point, it is crucial to find professional treatment.

Common Signs and Symptoms of Substance Use Disorder

The signs and symptoms of the substance vary depending on the substance used, but are typically:

Behavioral Signs

Taking more than directed.
Difficulty stopping
Spending a lot of time to get substances
Neglecting responsibilities
Risky behaviors
Even though there may be consequences, continued use.

Physical Signs

Changes in sleep
Weight changes
Bloodshot eyes
Poor coordination
Withdrawal symptoms
Increased tolerance

Emotional Signs

Mood swings
Anxiety Depression
Irritability Loss of motivation
Secretive behavior

Early detection of these signs enables treatment to be started before complications set in.

How Healthcare Professionals Diagnose Substance Use Disorder

The diagnosis of SUD is not made based on a single laboratory test, but by making a comprehensive evaluation.

Typically involves:

Clinical Interview

Providers ask about:

Substance use history
Medical history
Mental health
Family history
Lifestyle

DSM-5 Criteria

Based on the experts, all of the following symptoms are possible signs of Substance Use Disorder:

Intended use overused: Use of products in excess of recommended use.
Difficulty cutting down
Cravings
Neglecting responsibilities
Using despite issues
Withdrawal
Tolerance

Mild, moderate or severe depends on the number of criteria that are met.

Physical Examination

A healthcare professional can give a diagnosis for overall health evaluation and/or medical conditions resulting from drug use.

Mental Health Assessment

A large number of people who have SUD also have:

Anxiety disorders
Depression
PTSD
Bipolar disorder

Treatment of both conditions is likely to be more effective.

Treatment Options for Substance Use Disorder and Addiction

Everyone’s healing process is different. Physical treatment and emotional treatment should be part of the treatment plan.

Medication-Assisted Treatment (MAT)

Lifestyle Changes

Regular exercise
Healthy nutrition
Good sleep habits
Stress management
