Addiction in a young adult can look very different from addiction later in life.
Between approximately ages 18 and 25, many people are simultaneously navigating greater independence, changing relationships, work or college, financial pressure, housing decisions, mental health, identity and a rapidly changing social environment.
Substance use can become woven into these transitions before the young adult or family fully recognizes that control is being lost.
The problem does not always look like the stereotype of severe addiction.
It may initially look like:
- drinking every weekend and increasingly during the week;
- using cannabis throughout the day;
- using pills bought from friends or social media;
- taking stimulants to study or work longer;
- using opioids to manage emotional or physical pain;
- missing work or university;
- sleeping all day and staying awake all night;
- increasing anxiety, depression or isolation;
- borrowing money or becoming secretive;
- repeatedly promising to stop but returning to the same pattern.
Early recognition matters because a developing problem is generally easier to address before severe medical, psychological, financial and relationship consequences accumulate.
Young Adults Need Treatment That Builds a Future — Not Only Treatment That Stops a Drug
Effective care should address substance use alongside mental health, relationships, education or employment, housing, recovery skills, social environment and the person’s own goals.

View Dr Fergus Law’s Clinical & Scientific Profile →What Do We Mean by “Young Adult”?
SAMHSA commonly defines young adults or transition-age youth as people approximately 18 to 25 years old.
They are legally adults, but this period remains developmentally different from later adulthood.
NIMH notes that the brain continues maturing into the mid-to-late 20s. The prefrontal cortex — involved in planning, prioritizing and decision making — is among the later areas to mature.
This should not be interpreted to mean that young adults are incapable of making decisions.
It means treatment should recognize the developmental context in which decisions are being made.
Adolescents need age-specific assessment and treatment. The principles in this article can still be useful, but medication, consent, confidentiality and family involvement may differ for minors.
Why Young Adulthood Can Be a Vulnerable Period
Young adulthood often combines more freedom with less external structure.
Independence
Parents or schools may no longer structure daily behavior.
Peer Influence
Friends, relationships and social belonging can strongly shape behavior.
Life Transitions
College, work, moving away, relationships and financial pressure can increase stress.
Mental Health
Depression, anxiety, trauma and substance use frequently interact.
When Does Substance Use Become a Substance Use Disorder?
Not every young adult who has consumed alcohol, cannabis or another substance has an addiction.
The concern increases when substance use starts producing loss of control, impairment, risk or continued use despite harm.
Occasional Use Without Clear Loss of Control
This can still carry health or legal risks, but it is not automatically a substance use disorder.
Use Is Beginning to Control Life
Attempts to cut down fail, responsibilities suffer, risky use continues and the substance occupies increasing time or attention.
Questions That Matter More Than “How Often?”
Warning Signs of a Developing Addiction
Repeated Failed Attempts to Cut Down
The person repeatedly intends to stop or reduce use but returns to the same pattern.
Work or Education Declines
Missed shifts, falling grades, lateness, dropping out or losing previously important goals.
Conflict and Isolation Increase
New secrecy, withdrawal from family or repeated conflict about use.
Spending Becomes Difficult to Explain
Borrowing, unpaid bills or selling possessions may appear.
Sleep, Appetite or Mood Change
Substance use and mental health can reinforce one another.
Riskier Situations Appear
Driving impaired, mixing substances, unknown pills or using alone may sharply increase danger.
Mental Health and Substance Use Often Need to Be Addressed Together
SAMHSA’s young-adult recovery guidance emphasizes the connection between mental health and substance use.
A person may use alcohol or drugs to manage:
- anxiety;
- depression;
- trauma;
- social discomfort;
- loneliness;
- ADHD-related difficulties;
- sleep problems;
- emotional distress.
Substance use can also worsen or produce psychiatric symptoms.
In the 2025 NSDUH, about 11.1% of U.S. adults ages 18–25 had both a past-year substance use disorder and any mental illness.
Suicidal thoughts, psychosis, severe agitation, inability to stay safe or another acute psychiatric crisis needs urgent assessment. In the United States, call or text 988. Call 911 for immediate danger or a medical emergency.
Treatment Needs to Fit College, Work — or Neither
Young-adult addiction campaigns often focus heavily on universities.
SAMHSA specifically highlights the need to reach young adults who are not attending four-year colleges.
A young adult may be:
Treatment planning should therefore ask:
Recovery becomes more sustainable when treatment helps rebuild a realistic path toward education, employment, stable housing, relationships and purpose.
Fentanyl and Counterfeit Pills: A Critical Young-Adult Safety Issue
Illegally manufactured fentanyl is frequently mixed with other drugs and can also be pressed into counterfeit tablets made to resemble legitimate prescription medications.
CDC warns that this creates particular risk for youth and young adults who may believe they are taking a familiar prescription pill while unknowingly being exposed to fentanyl.
A Pill That Did Not Come From a Licensed Pharmacy Cannot Be Reliably Judged by Its Appearance
Counterfeit pills can closely imitate legitimate prescription products.
Screening Can Identify Problems Before the Situation Becomes Severe
SAMHSA promotes Screening, Brief Intervention and Referral to Treatment — SBIRT as an evidence-based public-health approach.
Screening
Quickly identify the severity of substance use and whether further assessment is needed.
Brief Intervention
Increase awareness and motivation for change using a nonjudgmental conversation.
Referral to Treatment
Connect people who need more intensive help to appropriate care.
Screening can happen in primary care, emergency departments, behavioral-health services and other community settings.
Treatment does not have to wait until somebody loses their job, education, relationships, housing or health.
What Effective Young-Adult Addiction Treatment Should Include
Identify the Disorder
Substance, severity, physical dependence, withdrawal risk, medical health and previous treatment.
Treat Co-Occurring Problems
Anxiety, depression, trauma, ADHD and other conditions should not automatically be separated from addiction care.
Build Skills
CBT, motivational approaches, contingency management, relapse prevention and other evidence-based therapies may help.
Use It When Evidence Supports It
Medication should be considered for opioid and alcohol use disorders rather than excluded because of stigma.
Improve the Recovery Environment
Supportive family involvement and healthier peer connections can strengthen treatment.
Rebuild a Life
Work, education, housing, relationships and meaningful activity are part of recovery.
How Parents and Families Can Help a Young Adult
A young adult is an adult.
Family support can still be enormously valuable, but the conversation generally works better when it supports autonomy rather than becoming a battle for control.
Describe What You See
“You have missed work three times this month and I am worried.”
Character Attacks
Labels, humiliation and moral judgments often increase defensiveness.
Ask About Their Goals
Connect treatment with what the young adult wants from life.
Financing Dangerous Use
Support recovery without providing money or conditions that directly enable substance use.
Offer Practical Help
Help find treatment, transportation, insurance information or appointments.
Prepare for Emergencies
Families around opioid exposure should know overdose signs and have naloxone available.
What if the Young Adult Does Not Want Treatment?
Lack of motivation does not mean that nothing can be done.
Motivational approaches begin with the person’s own goals rather than demanding an immediate declaration that they are “an addict.”
“You have ruined your life and need rehab.”
“You told me keeping this job matters to you. How do you think using is affecting that?”
SAMHSA recommends conversations with young adults that show concern without judgment and help connect substance use with future goals.
The first objective may be a medical appointment, screening, counseling session or treatment consultation — not necessarily immediate agreement to a long residential program.
Housing, Employment, Education and Purpose Are Part of Recovery
Removing a substance can leave a major empty space if the person’s social life, identity and routine previously revolved around using.
Recovery planning should therefore ask what fills that space.
SAMHSA has specifically funded young-adult recovery housing and services that can include care coordination, vocational training, employment support and transportation — reflecting how strongly recovery is tied to everyday functioning.
Naloxone and Overdose Safety
Where opioid exposure is possible, overdose preparedness should exist whether the opioid is being used intentionally or appears unexpectedly in a counterfeit product.
Naloxone rapidly reverses opioid overdose and can restore breathing.
How to Use Naloxone Nasal Spray
The U.S. Centers for Disease Control and Prevention provides this practical demonstration of how naloxone nasal spray is administered during a suspected opioid overdose.
Give naloxone if available and call 911. Support breathing according to emergency-dispatch instructions and stay with the person until emergency help arrives.
Young Adults With Opioid Use Disorder Should Be Offered Evidence-Based Medication
CDC identifies three FDA-approved medication approaches for opioid use disorder:
Methadone
Reduces withdrawal and craving and has strong evidence for treatment retention and reduced mortality.
Buprenorphine
Reduces withdrawal and craving and has strong evidence for reducing overdose and mortality.
Naltrexone
Blocks opioid receptors and can support prevention of return to opioid use after appropriate opioid withdrawal.
CDC advises against detoxification alone for opioid use disorder because returning to opioid use, overdose and overdose death remain risks.
Medication choice should be based on clinical circumstances and informed patient preference — not stigma about one medication being more “real recovery” than another.
Alcohol Problems in Young Adults Need More Than “Just Drink Less”
NIAAA specifically describes young adulthood as a transitional period in which vulnerability to alcohol misuse can increase.
Evidence-based approaches include:
Brief Motivational Intervention
Personalized feedback and motivational interviewing can help young adults examine how alcohol affects their goals.
Behavioral Treatment
CBT, motivational approaches and other therapies can address triggers, decisions and coping.
Medication
FDA-approved medications include naltrexone, acamprosate and disulfiram.
Severe alcohol withdrawal can be medically dangerous. A young adult with substantial daily drinking, previous withdrawal seizures, delirium or severe withdrawal symptoms should have a clinical withdrawal-risk assessment rather than abruptly stopping alone.
Cannabis, Stimulants and Other Substance Problems
Look for Loss of Control and Functional Impact
Frequent cannabis use can become a cannabis use disorder. Behavioral treatment can address motivation, routines, triggers and coping.
Behavioral Treatment Is Central
There is currently no FDA-approved medication for stimulant use disorder. SAMHSA identifies contingency management as a particularly effective treatment approach.
Misuse Is Not the Same as Prescribed ADHD Treatment
A clinical review should distinguish properly managed medication from misuse, escalating doses or use of medication not prescribed to the individual.
Do Not Assume One Treatment Covers Everything
Polysubstance use requires assessment of each substance, withdrawal risk, overdose risk and the function each substance serves.
Can a Naltrexone Implant Be Part of Treatment for a Young Adult?
For an adult aged 18–25 with an appropriate opioid or alcohol use disorder, naltrexone may be one medication option after individual medical assessment.
Naltrexone is an opioid-receptor antagonist.
For Opioid Use Disorder
Naltrexone can help prevent return to opioid dependence after appropriate detoxification.
The current U.S. extended-release injectable naltrexone label recommends a minimum opioid-free period of approximately 7–10 days before initiation to reduce the risk of precipitated withdrawal.
People transitioning from methadone or buprenorphine may remain vulnerable to precipitated withdrawal for longer, sometimes up to approximately two weeks.
For Alcohol Use Disorder
Naltrexone is an established medication for alcohol use disorder and can reduce the rewarding effects of alcohol and heavy drinking in some appropriately selected patients.
What About an Implant?
A sustained-release naltrexone implant is designed to maintain antagonist medication over a longer period than daily oral naltrexone or a monthly injection.
A potential practical advantage is reducing repeated medication decisions during a period when a young adult is also working on counseling, triggers, relationships, education, employment and recovery.
However:
The 2025 Cochrane review found potential benefits of sustained-release naltrexone compared with some alternatives such as oral naltrexone or treatment as usual, but important evidence gaps remain, particularly when comparing sustained-release naltrexone with opioid agonist treatments.
What Will the Young Adult Build During the Medication Window?
Long-acting medication has greater practical value when the period is used to build stable routines, work or education, healthy relationships, coping skills, counseling engagement and a realistic long-term recovery plan.
Long-Acting Naltrexone Plus Structured Counseling and Follow-Up
DeBinge treatment is based in the Bahamas and combines long-acting naltrexone treatment with professional counseling and continuing recovery support rather than treating the implant as a stand-alone solution.
A consultation should review the young adult’s substance use, current physical dependence, mental health, previous treatment, medical history, recovery environment and treatment goals before deciding whether an antagonist approach is appropriate.
What Should the Next Step Be?
This is not a knowledge quiz and it does not give somebody a label.
It is designed to identify what is happening now and turn the answers into a practical next-step roadmap.
Depending on the answers, the result may focus on:
- early screening and brief intervention;
- a full substance-use-disorder assessment;
- mental-health treatment;
- withdrawal assessment;
- opioid medication treatment;
- alcohol-use-disorder medication;
- behavioral treatment;
- family and peer support;
- naloxone and fentanyl safety;
- housing, work or education support.

Do Not Wait for a Routine Addiction Appointment
For a suspected opioid overdose, give naloxone if available and call 911.
Severe withdrawal, seizures, loss of consciousness, psychosis or another medical emergency needs urgent care.
For immediate suicide or self-harm danger, call 911. In the U.S., call or text 988 for crisis support.

Addiction in Young Adults FAQ
1. What age is considered a young adult?
SAMHSA commonly uses ages 18–25 when describing young adults or transition-age youth.
2. Why is addiction treatment different for young adults?
Young adults are often navigating brain maturation, independence, education, work, relationships, peer influence, housing and mental health at the same time.
3. Does frequent substance use automatically mean addiction?
No. Assessment focuses on loss of control, impairment, risk, craving, tolerance, withdrawal and continued use despite harm.
4. Should parents wait until the young adult hits rock bottom?
No. Early screening and intervention can occur before severe consequences develop.
5. Can mental health problems contribute to substance use?
Yes. Anxiety, depression, trauma and other mental-health conditions can interact strongly with substance use.
6. What is SBIRT?
Screening, Brief Intervention and Referral to Treatment is a public-health model for detecting risky use and connecting people to the appropriate level of care.
7. What if the young adult refuses rehab?
Start with a nonjudgmental conversation and a smaller achievable step such as screening, a medical appointment or a treatment consultation.
8. Should family be involved?
Family support can be very helpful when it respects the young adult’s autonomy and focuses on recovery rather than shame.
9. Are counterfeit prescription pills dangerous?
Yes. Illicit pills may contain fentanyl and cannot reliably be identified as safe by appearance.
10. Should young adults carry naloxone?
Naloxone should be readily available where opioid exposure or overdose risk exists.
11. What medications treat opioid use disorder?
FDA-approved options include methadone, buprenorphine and naltrexone.
12. Is opioid detox enough?
No. CDC advises that detoxification alone is not recommended treatment for opioid use disorder because return to use, overdose and overdose death risks remain.
13. What medications can help alcohol use disorder?
FDA-approved options include naltrexone, acamprosate and disulfiram.
14. Is naltrexone suitable for every addiction?
No. Naltrexone has established roles in alcohol and opioid use disorders. It is not a universal medication for every substance-use problem.
15. Can a young adult use naltrexone after opioids?
Yes, in appropriate adult patients, but adequate opioid-free preparation is essential because starting too early can precipitate severe withdrawal.
16. Is a naltrexone implant FDA-approved in the U.S.?
No. The FDA-approved long-acting U.S. naltrexone formulation is extended-release intramuscular naltrexone.
17. Can an implant replace counseling?
No. Medication does not directly resolve peer influence, mental health, housing, employment, family relationships or learned behavioral triggers.
18. What works for stimulant addiction?
SAMHSA identifies contingency management as a particularly effective treatment approach. There is currently no FDA-approved medication for stimulant use disorder.
19. Can recovery continue while a young adult works or studies?
Often yes. Treatment intensity should be matched to severity, safety and individual circumstances rather than assuming everyone needs the same treatment setting.
20. Where can someone in the U.S. find treatment?
FindTreatment.gov can locate substance-use and mental-health treatment services. SAMHSA’s National Helpline is 1-800-662-HELP (4357).
The Goal Is Not Simply to Stop Substance Use — It Is to Help a Young Adult Build a Life That Recovery Can Fit Into
Treatment works better when substance use, mental health, relationships, work or education, social environment and future goals are addressed together.
Medication may be important for opioid or alcohol use disorder, while behavioral treatment, family support and recovery structure help turn short-term stabilization into longer-term change.
When long-acting naltrexone is being considered, it should be one part of that wider plan rather than the entire plan.
