Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
Opioids are potent, addictive analgesics that trick and trap us by creating the fleeting euphoria of analgesia (pain-free), but the sustained sickness of hyperalgesia (pain-sensitivity). The euphoria of analgesia and the sickness of hyperalgesia are polar opposites that reinforce each other: the euphoria blinds us to the sickness, and the sickness makes us crave the euphoria. Perversely but predictably, opioids create, aggravate, and perpetuate the very sickness of hyperalgesia that they falsely seem to cure, thus placing many potent analgesics in a bad light.
