Healing Begins Here

How Marijuana Addiction Develops
Chronic marijuana use can also significantly reduce verbal communication skills and cognitive function. Long-term use can affect memory, attention, and the ability to process and retain information. Some of these neurological changes may be permanent, particularly when use begins in adolescence or continues heavily into adulthood. Understanding how marijuana affects the brain is a critical part of why professional treatment at a marijuana rehab center is so important; quitting on your own without addressing these underlying changes is extremely difficult.
Marijuana Withdrawal
Without a steady supply of marijuana, withdrawal symptoms and cravings can begin within 12 hours and last three to four weeks. Symptoms typically peak around 48 to 72 hours, which is when most people relapse without professional help. Common marijuana withdrawal symptoms include:
- Irritability, anxiety, and restlessness
- Sleep disturbances and insomnia
- Decreased appetite and weight loss
- Depressed mood
- Headaches and physical discomfort
- Intense cravings for marijuana
- Difficulty concentrating
A THC detox typically lasts approximately two weeks in total, though this varies depending on the frequency and duration of use, the individual’s metabolism, and overall health. At Crestview Recovery, clients going through withdrawal are supported with medical oversight and, when appropriate, medication to ease symptoms and reduce the risk of relapse during the most difficult early days of recovery.
Who Is at Risk for Marijuana Addiction?
People who begin using marijuana at a young age are also at greater risk, as early exposure has been shown to increase the likelihood of dependence and can have a more pronounced impact on brain development. Additionally, individuals with a family history of addiction or substance use disorders carry a genetic predisposition that makes them more vulnerable. At Crestview Recovery, we treat young adults and can help address the specific ways addiction affects them.
Because marijuana addiction is so frequently connected to underlying mental health issues, treatment must address both the substance use and the psychological factors driving it. At Crestview Recovery, we offer dual diagnosis treatment for clients with co-occurring conditions, providing integrated care that treats the whole person, not just the addiction.

The Connection Between Marijuana Use and Mental Health
This is why integrated, dual diagnosis treatment is essential for so many people struggling with marijuana addiction. At Crestview Recovery, our clinical team is experienced in identifying and treating co-occurring disorders, ensuring that both conditions are addressed simultaneously for the best possible long-term outcomes.

Marijuana Treatment Center FAQ
The most common and effective treatment for marijuana use disorder is behavioral therapy, particularly cognitive behavioral therapy (CBT) and motivational enhancement therapy (MET). These approaches help individuals identify triggers, develop coping strategies, and build motivation for lasting change. CBT works by helping clients recognize the thought patterns and emotional triggers that lead to use, while MET focuses on strengthening a person’s own internal motivation to recover.
At Crestview Recovery, our marijuana treatment program in Portland combines evidence-based therapies with group counseling, family therapy, and holistic support for a comprehensive approach to recovery.
The length of marijuana rehab depends on the severity of the addiction and each person’s individual needs. Outpatient programs may run for several weeks to a few months, while residential programs typically last 30, 60, or 90 days. Some clients benefit from transitioning through multiple levels of care, beginning in a residential program and stepping down to outpatient treatment as their recovery progresses.
At Crestview Recovery, we offer multiple levels of care, including intensive outpatient, partial hospitalization, and residential programs, so treatment length is always tailored to what each client actually needs for lasting recovery.
Research has linked heavy or long-term marijuana use to increased risk of anxiety disorders, depression, and psychosis, particularly in individuals with a genetic predisposition. Cannabis use can worsen existing mental health conditions and in some cases trigger new ones. For individuals already managing a mental health diagnosis, marijuana may feel helpful in the short term, but it typically worsens symptoms over time. At Crestview Recovery, we offer dual diagnosis treatment to address both marijuana addiction and any co-occurring mental health conditions simultaneously.
Signs of marijuana use disorder include using more cannabis than intended, spending significant time obtaining or recovering from its use, and continuing to use despite negative consequences in work, school, or relationships. Other signs include repeated failed attempts to cut back, strong and persistent cravings for marijuana, and relying on it to cope with stress, anxiety, or difficult emotions rather than addressing those issues directly. If you or someone you love recognizes these patterns, professional treatment at a marijuana addiction rehab center can help.
