A Study of Genetic Variation Influencing Pain and Response to Opioid Medications

Withdrawn before enrolling

Conditions studied: Pain

In brief

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.
