Prescription opioid medications are widely used in cancer pain and acute non-cancer pain management, so it is important to understand the factors relating to opioid use. This study will investigate: the relationship between the uses of prescribed opioid medication by those experiencing chronic non-cancer pain and a wide range of demographic, lifestyle, health and social factors; and the usage patterns of long-term opioid therapy by such patients.
