The second aim was to identify the factors associated with N2O use. All students in medicine, dentistry, pharmacy and midwifery of the Montpellier University were contacted by email to participate in the survey. The students answered directly online by filling out anonymously a questionnaire including demographic information and questions about N2O, illicit drugs and alcohol use. Ethical approval was granted by the ethics committee of the Montpellier University. The sample comprised 593 students (mean age = 22.3 \u00b1 2.6 yr), with 68.6% of females. Lifetime N2O use was reported by 76.6% and frequent alcohol use by 30.5% of the respondents. The lifetime use of cannabis, \u2018poppers\u2019, cocaine, ecstasy and LSD was 26.8%, 54.6%, 9.6%, 10.1% and 2.0% respectively. In multivariate analysis, the substances significantly associated with lifetime N2O were alcohol drinking and \u2018poppers\u2019 use. With respect to this self-nominated sample, our results indicate that respondents who were alcohol drinkers, were poppers users, follow longer studies, divert medical products for recreational use or were members of a students\u2019 corporation had higher odds of lifetime N2O use.<\/jats:p>","DOI":"10.3390\/ijerph19095237","type":"journal-article","created":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T02:14:39Z","timestamp":1650939279000},"page":"5237","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Recreational Nitrous Oxide Use and Associated Factors among Health Profession Students in France"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3660-2391","authenticated-orcid":false,"given":"Camille","family":"Inquimbert","sequence":"first","affiliation":[{"name":"Department of Public Health, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"},{"name":"Institut Desbrest d\u2019Epid\u00e9miologie et de Sant\u00e9 Publique, IDESP UMR UA11 INSERM, Universit\u00e9 de Montpellier, 34093 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoann","family":"Maitre","sequence":"additional","affiliation":[{"name":"EA 2415, Aide \u00e0 la D\u00e9cision pour une M\u00e9decine Personnalis\u00e9e, Universit\u00e9 de Montpellier, 34093 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estelle","family":"Moulis","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent","family":"Gremillet","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Tramini","sequence":"additional","affiliation":[{"name":"Department of Public Health, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"Valcarcel","sequence":"additional","affiliation":[{"name":"Department of Public Health, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0274-3065","authenticated-orcid":false,"given":"Delphine","family":"Carayon","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dental Medicine, University of Montpellier, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"429","DOI":"10.5005\/jp-journals-10005-1658","article-title":"Assessment of an Equimolar Mixture of Oxygen and Nitrous Oxide: Effects in Pediatric Dentistry","volume":"12","author":"Allio","year":"2019","journal-title":"Int.
