Substance Abuse Treatment in Irvine, California
Compassionate psychiatric evaluation and individualized treatment planning for alcohol, opioids, fentanyl, stimulants, cannabis, prescription medications, and co-occurring mental health concerns.

Understanding Substance Use Disorders
A substance use disorder is a medical and psychiatric condition involving a pattern of alcohol or drug use that causes significant problems with health, safety, relationships, responsibilities, or daily functioning.
Substance use can affect judgment, mood, sleep, memory, physical health, motivation, and emotional regulation. Some individuals continue using despite wanting to stop because cravings, withdrawal symptoms, stress, trauma, or untreated mental health concerns make change difficult.
Substance use disorder is not a personal failure. Treatment should be compassionate, confidential, and based on the substance involved, medical risks, psychiatric symptoms, previous treatment, and the patient's recovery goals.
Common Signs of a Substance Use Disorder
Symptoms vary by substance, frequency of use, withdrawal risk, medical history, and the impact on daily life.

Strong cravings or persistent thoughts about substance use
Repeated unsuccessful attempts to reduce or stop use
Needing increasing amounts to experience the same effect
Experiencing withdrawal symptoms when reducing or stopping use
Missing work, school, family, or personal responsibilities
Continuing substance use despite physical or mental health problems
Relationship, financial, legal, or occupational difficulties

Substances We May Address
Treatment planning depends on the substance involved, current use, withdrawal risk, medical condition, psychiatric symptoms, and the appropriate level of care.
Opioids
Opioid use disorder may involve fentanyl, heroin, or prescription pain medications. Treatment planning may include withdrawal-risk assessment, overdose prevention, medication options, psychiatric care, and recovery support.
Alcohol
Alcohol use disorder may affect mood, sleep, memory, relationships, physical health, and daily functioning. Abrupt withdrawal can be medically dangerous for some individuals and may require urgent medical evaluation.
Stimulants
Cocaine, methamphetamine, and prescription stimulant misuse may contribute to anxiety, insomnia, agitation, paranoia, depression, cardiovascular symptoms, or psychosis.
Cannabis
Problematic cannabis use may affect motivation, concentration, anxiety, sleep, relationships, and functioning. In some individuals, cannabis may worsen paranoia or psychotic symptoms.
Sedatives and Anti-Anxiety Medications
Misuse of benzodiazepines and other sedating medications may lead to tolerance, dependence, impaired coordination, memory problems, and dangerous withdrawal symptoms.
Multiple Substances
Some patients use more than one substance. Combining opioids, alcohol, sedatives, or other drugs can substantially increase overdose and medical risks.

Comprehensive Substance-Use Evaluation
The first step is understanding the full pattern of substance use, medical risk, mental health, functioning, and recovery needs.
Review Substance-Use History
We discuss the substances used, frequency, amount, duration, route of use, periods of abstinence, cravings, withdrawal symptoms, previous treatment, and recovery goals.
Assess Medical and Safety Risks
The evaluation considers overdose history, withdrawal risk, current intoxication, pregnancy, medical conditions, medication interactions, and the possible need for emergency, inpatient, or medically supervised care.
Evaluate Mental Health
We assess depression, anxiety, trauma, ADHD, bipolar symptoms, psychosis, sleep problems, suicidal thoughts, and other concerns that may occur alongside substance use.
Create an Individualized Plan
Recommendations may include medication management, Suboxone treatment when appropriate, psychotherapy, recovery support, laboratory or medical evaluation, referrals, and ongoing psychiatric follow-up.
Substance Abuse Treatment Options
Treatment is individualized and may involve one or more services depending on the substance involved, withdrawal risk, mental health concerns, and recovery goals.
Psychiatric Evaluation
A comprehensive psychiatric evaluation helps identify substance-use patterns, medical risks, withdrawal concerns, co-occurring mental health conditions, and the most appropriate level of care.
Explore Psychiatric EvaluationMedication Management
Medication may be one of the possible treatment options depending on the substance involved, diagnosis, withdrawal risk, medical history, previous response, and treatment goals.
Explore Medication ManagementSuboxone Treatment
For eligible patients with opioid use disorder, buprenorphine and naloxone treatment may help reduce opioid cravings and withdrawal symptoms as part of a comprehensive recovery plan.
Explore Suboxone TreatmentIndividual Therapy
Therapy may help patients identify triggers, strengthen coping skills, address trauma, improve emotional regulation, rebuild relationships, and develop relapse-prevention strategies.
Explore Individual TherapyCo-Occurring Mental Health Conditions
Substance use and mental health concerns frequently affect each other. Treating only one part of the problem may leave important symptoms unaddressed.
Withdrawal Can Require Medical Care
Withdrawal from alcohol, benzodiazepines, and some other substances can cause seizures, severe confusion, unstable vital signs, or other dangerous complications. Abruptly stopping a substance without medical guidance may be unsafe.
Outpatient Care Is Not Always Enough
Some individuals may need medically supervised detoxification, residential treatment, intensive outpatient care, hospitalization, or emergency services. An evaluation helps determine the safest and most appropriate level of treatment.
Recovery Can Include More Than One Approach
Treatment may include medication, therapy, medical care, peer support, structured recovery programs, family involvement, relapse-prevention planning, and regular follow-up.

Frequently Asked Questions
What is a substance use disorder?
A substance use disorder is a medical and psychiatric condition involving continued alcohol or drug use despite significant problems with health, functioning, safety, relationships, or responsibilities.
Is substance use treatment only for severe addiction?
No. Professional assessment may be helpful whenever alcohol or drug use is causing concern, increasing risk, affecting mental health, or becoming difficult to control.
Does substance abuse treatment always involve medication?
No. Medication is one of the possible treatment options. Treatment may also include psychiatric evaluation, psychotherapy, recovery support, behavioral strategies, medical care, referrals, or a higher level of treatment.

Yes. Depression, anxiety, PTSD, bipolar disorder, ADHD, psychosis, and sleep problems may occur alongside substance use disorders. Both concerns should be assessed during treatment planning.

Suboxone may be considered for eligible patients with opioid use disorder after an individualized evaluation. Treatment may include medication management, monitoring, counseling, and recovery support.
When is emergency care necessary?
