Given the widespread use of opium and its derivatives by millions of people across the world, the classification of opium consumption as a \"Group 1\" carcinogen has important public health ramifications. In this mini-review, we offer a short history of opium use in humans and briefly review the body of research that led to the classification of opium consumption as carcinogenic. We also discuss possible mechanisms of opium\u2019s carcinogenicity and potential avenues for future research.<\/jats:p>","DOI":"10.34172\/aim.2020.95","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T15:22:14Z","timestamp":1605108134000},"page":"757-760","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Fifty Years of Research and One Conclusion: Opium Causes Cancer"],"prefix":"10.34172","volume":"23","author":[{"given":"Mahdi","family":"Sheikh","sequence":"first","affiliation":[{"name":"Genetic Epidemiology Group, Section of Genetics, International Agency for Research on Cancer, World Health Organization, Lyon, France"},{"name":"Digestive Oncology Research Center, Digestive Diseases Research Institute, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farin","family":"Kamangar","sequence":"additional","affiliation":[{"name":"Department of Biology, School of Computer, Mathematical, and Natural Sciences, Morgan State University, Baltimore, MD, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reza","family":"Malekzadeh","sequence":"additional","affiliation":[{"name":"Digestive Oncology Research Center, Digestive Diseases Research Institute, Tehran University of Medical Sciences, Tehran, Iran"},{"name":"Digestive Disease Research Center, Digestive Diseases Research Institute, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2020,10,17]]},"container-title":["Archives of Iranian Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-757.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/www.aimjournal.ir\/PDF\/aim-23-757.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T15:22:14Z","timestamp":1605108134000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.aimjournal.ir\/Article\/aim-19929"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,10,17]]},"references-count":0,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2020,11]]}},"URL":"https:\/\/doi.org\/10.34172\/aim.2020.95","relation":{},"ISSN":["1029-2977","1735-3947"],"issn-type":[{"value":"1029-2977","type":"print"},{"value":"1735-3947","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,10,17]]},"assertion":[{"value":"Academy of Medical Sciences of the I.R.
