Do you offer medical detox?

Yes. We provide medically supervised detoxification for alcohol and drug dependency, managed by our consultant psychiatrists and experienced nursing team. Detox is always the first step before therapeutic rehabilitation begins.

What is dual diagnosis?

Dual diagnosis means the co-occurrence of addiction and another mental health condition, such as depression, anxiety, or PTSD. At Cardinal Clinic, we treat both conditions simultaneously, because addressing only one rarely leads to lasting recovery.

How long is a typical residential stay for addiction treatment?

Residential stays typically range from 4 to 12 weeks, depending on the severity of the addiction and any co-occurring conditions. Your consultant will recommend a realistic timeframe during your assessment.

Addiction is a chronic condition, not a moral failing. With the right clinical framework and sustained support, lasting recovery is not only possible — it is the expected outcome.
