Patients with chronic pain understandably seek relief from their distress and discomfort, but many medications that alleviate pain are potentially addictive, and most chronic pain conditions only have a temporary response to opiate analgesic drugs. This volume reviews the fundamental topics that underlie the complex relationships of this controversial domain. The authors review behavioral models and practical methods for understanding and treating chronic pain and addiction including methods to formulate patients with complex comorbidity and screen patients with chronic pain for addictive liability. Finally, the authors describe the current findings from clinical and basic science that illuminate the role of opiates, cannabinoids and ketamine in the treatment of chronic pain. Up to date and comprehensive, this book is relevant to all professionals engaged in the care of patients with chronic pain or addiction and all others interested in these contemporary issues, particularly non-clinicians seeking clarity in the controversy over the best approach to patients with chronic pain.
