Little is known about peer crowds prevalent among Asian American, Native Hawaiian, and other Pacific Islander (AANHPI) populations and the peer crowds\u2019 normative tobacco and other substance use behavior. To address this gap in knowledge, this study conducted focus groups with young adult community college students. Methods: Focus group discussions were conducted with a convenience sample of 42 young adults (Mean age = 21.5, SD = 2.7) recruited across community colleges on O\u2018ahu, Hawai\u2018i. The participants represented 60% women, 55% NHPI, and 29% Asian American. Results: Results indicated the presence of a wide range of peer crowds in the population, which may be classified into the following seven categories prevalent in the literature: Regular, Academic, Alternative, Athlete, Geek, High Risk, and Popular. Several peer crowds within the Alternative, Athlete, Geek, High Risk, and Popular categories appeared to represent subcultures relevant for NHPI young adults. High-risk peer crowds were reported to be vulnerable to different types of substance use. Tobacco product use, particularly e-cigarette use or vaping, was noted to be characteristically present among Popular crowds and certain Athlete crowds. Conclusion: Tobacco and other substance use prevention interventions, such as mass media campaigns, may benefit from targeting high-risk peer crowds, especially those relevant for NHPI young adults, who are at high risk for tobacco and other substance use. E-cigarette use prevention interventions may benefit from paying close attention to vulnerable Popular and Athlete groups.<\/jats:p>","DOI":"10.3390\/ijerph20021029","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T01:48:19Z","timestamp":1672969699000},"page":"1029","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Peer Crowds and Tobacco Product Use in Hawai\u2018i: A Qualitative Study"],"prefix":"10.3390","volume":"20","author":[{"given":"Kayzel R.","family":"Tabangcura","sequence":"first","affiliation":[{"name":"Population Sciences in the Pacific Program, University of Hawai\u2018i Cancer Center, University of Hawai\u2018i at M\u0101noa, 701 Ilalo St., Honolulu, HI 96813, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Taketa","sequence":"additional","affiliation":[{"name":"Population Sciences in the Pacific Program, University of Hawai\u2018i Cancer Center, University of Hawai\u2018i at M\u0101noa, 701 Ilalo St., Honolulu, HI 96813, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0335-6275","authenticated-orcid":false,"given":"Crissy T.","family":"Kawamoto","sequence":"additional","affiliation":[{"name":"Population Sciences in the Pacific Program, University of Hawai\u2018i Cancer Center, University of Hawai\u2018i at M\u0101noa, 701 Ilalo St., Honolulu, HI 96813, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samia","family":"Amin","sequence":"additional","affiliation":[{"name":"Population Sciences in the Pacific Program, University of Hawai\u2018i Cancer Center, University of Hawai\u2018i at M\u0101noa, 701 Ilalo St., Honolulu, HI 96813, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6778-9718","authenticated-orcid":false,"given":"Steve","family":"Sussman","sequence":"additional","affiliation":[{"name":"Department of Population and Public Health Sciences, Keck School of Medicine, University of Southern California, SSB 302A 2001 N.
