There were also significant differences across age groups. Women comprised a greater proportion of treatment episodes involving methamphetamine use (43.3%) compared to all other drugs combined (33.6%). Latinas represented 45.5% of methadone-related admissions. Compared with other drug users, methamphetamine users had a lower successful treatment completion rate and were served by programs with less financial and culturally responsive capacity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Findings highlight a sharp increase in treatment admissions for methamphetamine users of all gender and ethnocultural groups. Women, especially Latinas, saw the most significant increases, with a widening gender gap over time. All subgroups of methamphetamine users had a lower treatment completion rate compared with users of other drugs, and critical differences existed in the programs where they received services.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11782218231180043","type":"journal-article","created":{"date-parts":[[2023,6,7]],"date-time":"2023-06-07T07:16:58Z","timestamp":1686122218000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Exploring Gender and Ethnoracial Differences and Trends in Methamphetamine Treatment"],"prefix":"10.1177","volume":"17","author":[{"given":"Erick G","family":"Guerrero","sequence":"first","affiliation":[{"name":"Research to End Health Disparities Corp, I-Lead Institute, Los Angeles, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hortensia","family":"Amaro","sequence":"additional","affiliation":[{"name":"Florida International University, Herbert Werthein College of Medicine and Robert Stempel College of Public Health and Social Work, Miami, FL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinfei","family":"Kong","sequence":"additional","affiliation":[{"name":"California State University, Fullerton, College of Business and Economics, Fullerton, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tenie","family":"Khachikian","sequence":"additional","affiliation":[{"name":"University of Chicago, Crown Family School of Social Work and Social Policy, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanne C","family":"Marsh","sequence":"additional","affiliation":[{"name":"University of Chicago, Crown Family School of Social Work and Social Policy, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,6,7]]},"reference":[{"key":"bibr1-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2021.2588"},{"key":"bibr2-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1111\/1556-4029.14153"},{"key":"bibr3-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1093\/jat\/bkaa068"},{"key":"bibr4-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2020.4321"},{"key":"bibr5-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1126\/science.aau1184"},{"key":"bibr6-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1111\/add.14812"},{"key":"bibr7-11782218231180043","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugalcdep.2019.107592"},{"key":"bibr8-11782218231180043","unstructured":"Volkow N.
