About Substance Abuse Treatment in Costa Mesa

Substance addiction, also known as substance use disorder, is a complex and challenging medical condition that affects millions of individuals and their families across the country. Characterized by the compulsive use of drugs or alcohol despite negative consequences, substance addiction can impact every aspect of a person’s life—including their physical health, mental well-being, relationships, and daily functioning.

In Costa Mesa, CA, and throughout Orange County, addiction treatment centers are dedicated to helping individuals overcome drug and alcohol addiction through a variety of evidence-based and holistic approaches. Recognizing the signs of substance addiction—such as withdrawal symptoms, changes in behavior, and increased tolerance—is an important first step in seeking help. Many people struggling with addiction also experience mental health concerns like anxiety, depression, or personality disorders, which can complicate the recovery process. This is why dual diagnosis treatment, which addresses both substance use and co-occurring mental health disorders, is so essential for lasting recovery.

Since frequency and duration affect costs, it’s important to confirm which codes and visit limits your plan covers. You should also check if your insurance cover rehab and which outpatient services are included in your plan, as coverage can vary between providers.
