By using a log\u2010linear model approach it was possible to correct for missing observations (heroin users who presented for treatment before 1991 and those who had still not presented by the end of 2005) and to estimate heroin incidence over time.<\/jats:p><jats:p><jats:bold>Findings\u2003<\/jats:bold> The estimated incidence of problematic heroin use in the population aged 15\u201344 peaked at 190 per 100\u2003000 in 1980\u2014after rising rapidly from less than 40 per 100\u2003000 in 1971\u2014and fell subsequently to about 8 per 100\u2003000 in 2005. On average, incidence was five times higher in men. Injecting heroin incidence peaked and declined rapidly from 1980; as heroin smoking did not decline as rapidly, from 1985 onwards its estimated incidence has remained above that of heroin injecting. The delay between starting heroin use and entering treatment had a median of 3 years.<\/jats:p><jats:p><jats:bold>Conclusions\u2003<\/jats:bold> We demonstrate the utility of a method to estimate heroin incidence from analysis of observed trends in presentations at specialist drug treatment facilities. The estimates suggest that incidence of heroin use, especially injecting, has fallen since 1980 and is now lower than in the early 1970s.<\/jats:p>","DOI":"10.1111\/j.1360-0443.2008.02451.x","type":"journal-article","created":{"date-parts":[[2009,1,15]],"date-time":"2009-01-15T10:23:10Z","timestamp":1232014990000},"page":"248-255","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Problematic heroin use incidence trends in Spain"],"prefix":"10.1111","volume":"104","author":[{"given":"Albert","family":"S\u00e1nchez\u2010Niub\u00f2","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep","family":"Fortiana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregorio","family":"Barrio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep Maria","family":"Suelves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Francisco","family":"Correa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ant\u00f2nia","family":"Domingo\u2010Salvany","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,1,15]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugalcdep.2007.03.007"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1590\/S1135-57272006000500009"},{"key":"e_1_2_7_4_2","volume-title":"Informe 2004","author":"Observatorio Espa\u00f1ol Sobre Drogas","year":"2004"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1360-0443.2003.00326.x"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a009694"},{"key":"e_1_2_7_7_2","volume-title":"Guidelines for Estimating the Incidence of Problem Drug Use","author":"Scalia Tomba G.
