All NSDUH participants who reported past-year prescription opioid use for non-medical reasons were asked about their most recent source of prescription opioids used for non-medical reasons. Responses to this question included: one doctor, more than one doctor, writing a fake prescription, stealing a prescription opioid from a physician’s office or clinic or hospital or pharmacy, obtaining from friends and family for free, buying from friend or family, taking from friend or family without asking, buying from a drug dealer or other stranger, obtaining from the internet, and some other way. Responses were recoded into six categories: prescription from one or more physician(s), stolen (from physician’s office or friends/family), obtained for free from friends or family, bought from friends or family, bought from a drug dealer or stranger, or other (combined writing fake prescription, internet, other). Questions about prescription opioid sources were not asked prior to 2005, thus the time period for these analyses was from 2005 to 2014.
