Drug-use surveys have shown an increasing prevalence of non-medical use of opioid pain medications. University of Chicago researchers writing in The Journal of Pain report that critical information would be learned about the problem if motives for non-medical use were studied more extensively.
Non-medical use of opioids is defined as using a pain medication even once that was not prescribed and was taken only to experience the felling it would cause.
AdvertisementThe authors reviewed the three major epidemiological surveys to measure the prevalence of non-medical use of opioids, but focused on the NSDUH (National Survey on Drug Use and Health) survey because it is the largest annual U.S. drug-use survey.
A key drawback the NSDUH survey identified by the authors is the instrument does not probe for motives or reasons for nonmedical use of opioids. For example, pain relief is a motive for using an opioid and so is getting high or inducing sleep.
The authors reviewed results from two web-based surveys, one of which polled 4580 students attending a large Midwestern university. To probe the prevalence of non-medical use of opioids the questionnaire asked: "On how many occasions in a) your lifetime or b) in the last 12 months have you used the following types of drugs not prescribed to you?" Respondents were given eight drug choices. They were then asked to provide the reasons for taking non-prescribed pain medications.
The results showed that lifetime and past 12 month incidence was 14.3 % and 7.5 %, respectively. Most of the respondents (63%) who said they were non-medical users reported that pain relief was the motive. Other common reasons cited were "because it gives me a high" and "experimentation." However, just 40 percent of lifetime non-medical users reported using opioids only to relieve pain.
Based on the web survey results, the authors recommended the NSDUH survey add questions about motives and survey officials should convene a summit with the American Pain Society and other groups to move forward in this direction.
