Risk of opioid misuse in chronic non-cancer pain in primary care patients - a cross sectional study.

While Germany does not face an "opioid eoidemic", addictiveness of opioids should be considered when using them in chronic non-tumor pain. In our study population, almost every third patient was at risk and should therefore be followed up closely. Co-prevalence of depression is a significant issue and should always be screened for in patients with chronic pain, especially thus with aberrant drug behaviour.
