We employed natural language processing (NLP) to study benzodiazepine mentions over 10\u2009years on 270 online drug forums (subreddits) on Reddit. Using NLP, we automatically detected mentions of illicit and prescription benzodiazepines, including their misspellings and non-standard names, grouping relative mentions by quarter. On a collection of 17\u200a861\u200a755 posts between 2012 and 2021, we searched for 26 benzodiazepines (8 prescription; 18 illicit), detecting 173\u200a275 mentions. The rate of posts about both prescription and illicit benzodiazepines increased consistently with increases in deaths involving both drug classes, illustrating the utility of surveillance via Reddit.<\/jats:p>","DOI":"10.1093\/eurpub\/ckac161","type":"journal-article","created":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T18:40:57Z","timestamp":1667846457000},"page":"939-941","source":"Crossref","is-referenced-by-count":14,"title":["Evidence
