Medical use of prescription opioids has steadily increased since the 1990s, particularly in the U.S.A. and Canada, along with abuse of these substances and significant increases in rates of addiction and death related to prescription opioids. The American authorities speak of an "addiction epidemic" and are launching a series of countermeasures to better address the problem. In Europe, there is an increasing use of prescription opioids and related problems, but the European context is much less dramatic than the American and Canadian ones. Never-theless, based on the data, it cannot be ruled out that a similar crisis will occur on the Old Continent. The aim of this study is to analyze the Italian context to better understand whether there is a possibility of an addiction epidemic. Twenty-four cases of death of people under treatment with pre-scription opioids have been retrospectively analyzed. Toxicological samples were collected with routine methods during the autopsy, followed by systematic screening for substances by diverse methods. Volatile compounds were identified using gas chromatography-flame ionization detection (GC-FID). Medical drugs and drugs of abuse were identified via the use of gas chromatography-mass spectrome-try (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS-MS). Of a total of 24 subjects, 14 died due to an overdose of Tramadol, while 7 died due to an overdose of Buprenorphine and 3 dues to a Fentanyl overdose. The most used drug was Tramadol. Histological examination was performed with hematoxylin/eosin staining, though no significant findings emerged apart from widespread edema and focal sclerosis of the myocardium, and interstitial and alveolar edema of the lungs. Our data show that attention must be paid to prescription opioids. European institutions, as soon as possible, must implement preventive measures that avoid the recurrence of the North American situation.
