This study has no listed site in Canada in this snapshot. It is included as part of the worldwide chronic pain corpus.
Brief summary (from the registry)
The investigators will be collecting saliva DNA samples from chronic back pain patients. The investigators hope to find candidate genes associated with response to opioid medication by correlating molecular genetics data with pain measurement and opioid responsiveness data including opioid hyperalgesia and opioid analgesic tolerance.
