Our treatment programs support clients to recover from addiction by processing past trauma, building resilience and self-worth, and developing healthy coping skills.

How To Tell If You or Your Loved One Has a Substance Use Disorder
What are the warning signs of addiction in teens and young adults? There are both behavioral and physical signs of drug use that parents and other loved ones might recognize.
In teens, the behavioral signs of teen substance use sometimes resemble typical teen angst or rebellion. That’s why it can be hard to tell the difference between difficult teen behavior and signs that an adolescent is struggling with a substance use disorder.
For young adults, the criteria for drug addiction depends not only on their behavior and physical symptoms, but also on how their substance use is impacting their daily life and functioning.
Below we list the signs and symptoms of teen and young adult drug use, as well as the criteria for substance use disorder.

What Causes Addiction?
Underlying mental health disorders are a primary cause of substance use disorder.
Teens and young adults typically begin using substances regularly as a form of self-medication. They may start by experimenting with a drug at a party or with peers.
But over time, it becomes a way to cope with the distress and emotional pain associated with depression, anxiety, PTSD, bipolar disorder, or another mental health condition. As a result, they become dependent on the drug—mentally, physically, or both.
In addition, drug addiction has a genetic component. Young people are more vulnerable to substance use disorder if they have a family member who is or was addicted to substances.
Risk Factors for Substance Use Disorder
The following factors make it more likely that a teen or young adult will start using substances and become dependent on them.
Mental health issues
Problem drug use in teens and young adults is usually a symptom of an underlying mental health disorder.
Family history of drug use
When parents, siblings, or extended family members have a history of addiction, teens are more likely to develop a substance use problem.
Age when they first use drugs
The younger a person is when they start using substances, the higher the risk of addiction. Early drug abuse in teens disrupts brain development, wiring the brain for addiction.
Childhood trauma
A Columbia University study found that adolescents who experienced childhood trauma, especially abuse and domestic violence, were more likely to experiment with drugs in adolescence.
Family rejection
LGBTQ youth who have experienced rejection due to their gender identity or sexual orientation have higher rates of teen drug use, according to the Trevor Project.

What Happens When Addiction Isn’t Treated
Untreated substance use can have a wide range of long-term impacts on teens, young adults, and their loved ones. Here are some of the key long-term effects:
- Physical health consequences: Prolonged substance use can lead to chronic health conditions such as liver disease, cardiovascular problems, respiratory issues, and infectious diseases (e.g., HIV, hepatitis).
- Neurological damage: Substances like alcohol and drugs can cause lasting changes to brain structure and function, leading to cognitive deficits, memory problems, and mental health disorders.
- Co-occurring disorders: Substance use often coexists with mental health disorders like depression, anxiety, and PTSD, which can get worse if left untreated.
- Cognitive impairment: Long-term use can impair decision-making, impulse control, and emotional regulation.
- Relationship strain: Substance use can lead to conflicts and breakdowns in relationships with family, friends, and colleagues.
- Employment issues: Young adults may face job loss, decreased productivity, or difficulty maintaining employment, leading to financial instability.
- Legal problems: Substance use can result in legal issues, including arrests, losing a driver’s license, and related costs.
- Isolation: Young people struggling with substance use may withdraw from social interactions, leading to loneliness and isolation.


Getting sober and healthy has brought me back up to speed and my memory is back. I treasure it now, all of the moments I thought once lost to time. The memories of the life I lived are now accessible to me again.

Diagnosing Substance Use Disorder in Teens and Young Adults
Diagnosis of a substance use disorder in young people involves a complete physical and mental health assessment. An evaluation for drug addiction may include any or all of the following:

Physical Exam
A physical exam will help determine how substance use is impacting physical health in addition to mental health.

Lab Tests
A doctor may conduct lab tests to screen for any potential medical impacts of long-term substance use.

In-depth Interview
A physician, psychiatrist, or other addiction specialist or healthcare provider may conduct an interview regarding drug use.
Teen and Young Adult Substance Use Disorder Treatment at Newport Healthcare
At Newport Healthcare, we address substance use disorder by helping young people process past trauma and replace destructive behaviors with healthy coping skills. Rather than addressing symptoms alone, we guide young adults to dig deeper so they can create the foundation for a thriving, substance-free life.
Clients uncover the root causes of their problem drug use and learn coping and emotion-regulation skills to support ongoing recovery. Teens and young adults develop healthy ways to work with challenging emotions rather than using substances to self-medicate.
One of the primary benefits of substance use disorder treatment in a residential treatment center is connection with others who are also on the healing journey. Newport Healthcare also has a robust alumni program, providing support groups and resources to help ensure ongoing recovery.
Our addiction treatment does not include withdrawal management (“detox”). Clients come to Newport after completing medical detox. Our program is the next step to support them in achieving long-term healing and recovery.

Frequently Asked Questions
Early signs of addiction include increased tolerance, cravings, constantly thinking about using the drug, and loss of interest in other activities you used to enjoy.
Substance use disorder in teens and young adults is often a symptom of an underlying mental health issue. Young people who experience pain and distress as a result of anxiety, depression, or trauma may use drugs as a way to numb the pain.
The five Ds are typically used as a way to cope with nicotine cravings, but for some people may be useful while in recovery from other substances. They are Delay (wait a few minutes to see if the craving passes); Distract (do something that takes your attention away from the craving), Drink water (this can help reduce cravings and ease symptoms); Deep breathing (to create relaxation); and Discuss (connecting with a sponsor, therapist, or support group).
Addictions to marijuana, alcohol, and prescription drugs are the most common substance use issues.
First, initiate a calm and open conversation with your child about their drug use. Let them know you’re worried about them and assure them that you are there for them no matter what. If you have concerns after this conversation, the next step is to schedule an evaluation to determine whether your child would benefit from a teen or young adult rehab program. Rehab will not only change your child’s life for the better, it may even save their life.
