Overview

Substance Use Disorder (SUD), often referred to as addiction, is a complex medical condition characterized by an inability to control the use of a substance despite harmful consequences. It's classified in the DSM-5-TR based on a pattern of cognitive, behavioral, and physiological symptoms indicating that an individual continues using a substance despite significant substance-related problems. The substances involved can range from illicit drugs (like cocaine, heroin, methamphetamine, cannabis) to legal substances such as alcohol, nicotine, and misused prescription medications (opioids, sedatives, stimulants). The severity of SUD can range from mild to severe, depending on the number of diagnostic criteria met. SUD fundamentally alters brain function, affecting impulse control, reward, memory, and motivation, making it a chronic, relapsing brain disease, not a moral failing.

Who it affects

Substance Use Disorder can affect anyone, regardless of age, gender, socioeconomic status, or ethnicity. Risk factors include genetics, environmental influences (such as peer pressure, physical and sexual abuse, early exposure to drugs), mental health conditions (like depression, anxiety, or post-traumatic stress disorder), and age of first use. Young people are particularly vulnerable as their brains are still developing. In Texas, like elsewhere, SUD impacts individuals, families, and communities, leading to significant health, social, and economic burdens. It is crucial to remember that SUD is a treatable condition, and recovery is possible for everyone.

Getting care in Texas

If you or someone you know is struggling with Substance Use Disorder in Texas, numerous treatment options are available. Diagnosis for SUD requires a comprehensive evaluation by a licensed clinician. Treatment often involves a combination of behavioral therapies, peer support, and sometimes medication. Texans can access care through various avenues, including in-person therapy at clinics and private practices, and increasingly, through telehealth services which offer convenient and accessible support. Local Mental Health Authorities (LMHAs) throughout Texas provide essential services, including crisis intervention, assessments, and referrals to treatment. With approximately 1,000 Texas-licensed mental-health providers, individuals can find qualified professionals to help navigate their recovery journey. If you are experiencing a mental health crisis, please call or text 988 to reach the 988 Suicide & Crisis Lifeline.

Common symptoms

  • Taking the substance in larger amounts or for longer than intended.
  • Expressing a persistent desire or unsuccessful efforts to cut down or control substance use.
  • Spending a great deal of time in activities necessary to obtain the substance, use the substance, or recover from its effects.
  • Craving, or a strong desire or urge to use the substance.
  • Recurrent substance use resulting in a failure to fulfill major role obligations at work, school, or home.
  • Continued substance use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of the substance.
  • Important social, occupational, or recreational activities are given up or reduced because of substance use.
  • Recurrent substance use in situations in which it is physically hazardous.
  • Continued substance use despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the substance.
  • Tolerance, as defined by either a need for markedly increased amounts of the substance to achieve intoxication or desired effect, or a markedly diminished effect with continued use of the same amount of the substance.
  • Withdrawal, as manifested by either the characteristic withdrawal syndrome for the substance, or the substance (or a closely related substance) is taken to relieve or avoid withdrawal symptoms.

Evidence-based treatments

  • Cognitive Behavioral Therapy (CBT)
  • Motivational Interviewing (MI)
  • Contingency Management (CM)
  • Family Behavior Therapy (FBT)
  • Twelve-Step Facilitation Therapy
  • Community Reinforcement Approach (CRA)
  • Eye Movement Desensitization and Reprocessing (EMDR) for co-occurring trauma
  • Detoxification (medically supervised withdrawal)
  • Medication-Assisted Treatment (MAT) for opioid use disorder (e.g., opioid agonists like buprenorphine, opioid antagonists like naltrexone)
  • Medications for alcohol use disorder (e.g., naltrexone, acamprosate, disulfiram)
  • Medications to manage withdrawal symptoms (e.g., benzodiazepines for alcohol withdrawal, non-opioid medications for opioid withdrawal)

Frequently asked about Substance Use Disorder

Is Substance Use Disorder curable?

Substance Use Disorder is considered a chronic, relapsing condition, similar to other chronic diseases like diabetes or asthma. While there isn't a 'cure' in the sense of complete eradication, it is highly treatable, and individuals can achieve long-term recovery and lead fulfilling lives. Recovery involves ongoing management and may include periods of relapse, which are part of the journey for many.

How is Substance Use Disorder diagnosed?

Diagnosis of Substance Use Disorder is made by a licensed clinician, such as a physician, psychiatrist, psychologist, or licensed therapist. They conduct a comprehensive evaluation based on criteria outlined in the DSM-5-TR, which involves assessing an individual's pattern of substance use, associated behaviors, and the impact on their life. This is not a self-diagnosis; professional assessment is crucial.

Do I need medication for Substance Use Disorder?

Whether medication is needed depends on the specific substance involved, the severity of the disorder, and individual circumstances. For some substances, such as opioids and alcohol, Medication-Assisted Treatment (MAT) is highly effective and considered a gold standard of care to reduce cravings and prevent relapse. For others, behavioral therapies alone may be sufficient. A healthcare provider will determine the most appropriate course of treatment.

How long does treatment for Substance Use Disorder take?

The duration of treatment for Substance Use Disorder is highly individualized and varies greatly. It can range from short-term detoxification programs to long-term outpatient therapy and ongoing recovery support, potentially lasting for years. The goal is sustained recovery, which often requires continued support and adaptation of treatment plans over time. Consistency and commitment are key.

Can I work or maintain responsibilities while in treatment for Substance Use Disorder?

Yes, many individuals successfully maintain employment, schooling, and other responsibilities while receiving treatment for Substance Use Disorder. Outpatient programs, telehealth options, and therapies like Cognitive Behavioral Therapy are designed to integrate into daily life. For more intensive needs, inpatient or residential programs may be necessary initially, often followed by a transition to outpatient care that supports reintegration into daily routines.

Can Substance Use Disorder be treated successfully?

Yes. Most cases of Substance Use Disorder respond to evidence-based therapy, with or without medication. Outcomes are best when treatment is started early and the client-therapist fit is strong. Many people see meaningful improvement within 8-20 weekly sessions.

What does therapy for Substance Use Disorder look like?

Treatment usually starts with a thorough assessment, goal-setting, and education about Substance Use Disorder. Sessions then use evidence-based methods (CBT, ACT, DBT, EMDR, IFS, or psychodynamic therapy, depending on the diagnosis and your preferences). Homework between sessions is common.

Will I need medication for Substance Use Disorder?

Not always. Many people manage Substance Use Disorder with therapy alone. For moderate-to-severe symptoms, medication can speed relief and make therapy more effective. A psychiatric provider (MD, DO, or PMHNP) — separate from your therapist — handles prescribing.

How do I know if it's really Substance Use Disorder or something else?

Self-screening tools are useful starting points, but only a licensed clinician can diagnose. Several conditions share overlapping symptoms (e.g., trauma, ADHD, thyroid issues, sleep disorders), so a thorough intake assessment is important before settling on a treatment plan.

Can I do Substance Use Disorder therapy by telehealth?

Yes. Research shows telehealth is as effective as in-person care for most outpatient mental-health conditions, including Substance Use Disorder. Every clinician in our directory is set up for secure video sessions across Texas.

Will my Substance Use Disorder diagnosis affect my job, security clearance, or insurance?

Therapy records are confidential under HIPAA. Diagnoses billed to insurance become part of your medical record but are not visible to your employer. Federal security clearances generally don't penalize people for seeking mental-health care — in fact, untreated symptoms are a bigger risk factor.

How soon should I see results?

Many people notice some relief within the first 4-6 sessions. Significant, durable change for Substance Use Disorder typically takes 3-6 months of weekly work, longer for complex or chronic presentations. Track progress with your therapist using brief check-in measures.

What if I'm in crisis with Substance Use Disorder right now?

If you're considering harming yourself or others, call or text 988 (Suicide & Crisis Lifeline, 24/7, English and Spanish) or go to the nearest emergency room. Any Texas ER is required to evaluate behavioral-health emergencies.
