Illegal Opioid Addiction Treatment
Confidential residential treatment for illegal opioid addiction, including medically supervised detoxification, psychiatric assessment, and intensive addiction therapy. Treatment is provided in a 24-hour clinical care setting, with individual qualification and planning for further recovery.

What Illegal Opioids Are
Illegal opioids are opioid substances produced or distributed outside the healthcare system, without control over quality, dosage, or safety. This group primarily includes heroin and illegally manufactured fentanyl, as well as their mixtures and derivatives.
These substances act on opioid receptors in the brain, producing strong pain-relieving and euphoric effects, while at the same time leading to rapid development of tolerance, physical and psychological dependence, and a high risk of overdose.

When Urgent Medical Help Is Necessary
Urgent medical help is necessary if, during withdrawal, there are seizures, loss of consciousness, severe disorientation, symptoms of psychosis, aggressive behaviour disproportionate to the situation, severe chest pain, shortness of breath, or suspected overdose. In such situations, self-treatment should not be attempted. The priority is patient safety and rapid clinical assessment. In life-threatening or health-threatening situations, emergency medical help should be requested immediately by calling 112.
The Mechanism of Opioid Addiction
Illegal opioids are associated with exceptionally high medical risk, including:
respiratory depression and sudden respiratory arrest,
overdose, especially in the case of fentanyl,
severe withdrawal syndromes,
infections such as HIV, hepatitis, and sepsis,
cardiovascular complications,
a significant risk of death.
The unpredictable purity and dose of these substances mean that even a single use may be fatal.
Symptoms of Opioid Addiction
Opioid addiction may involve the following symptoms:
Psychological and behavioural:
a strong compulsion to use the substance,
anxiety, irritability, depression,
neglect of responsibilities and relationships,
social isolation,
risky and compulsive behaviour.
Physical:
withdrawal symptoms such as muscle pain, sweating, chills, and diarrhoea,
insomnia,
physical deterioration,
breathing disturbances,
injection marks or damage to mucous membranes.
