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

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.

Stanford is currently accepting patients for this trial.
