The THz\u2010TDS method provided valuable information on the transmission spectra of tobacco and nicotine in smoking products. From the CO<jats:sub>2<\/jats:sub> LPAS data it was observed that in cigarette (TC) smoking the mean breath ethylene was 687\u2009parts per billion (ppb), while in electronic cigarettes and tobacco heating devices smoking the mean ethylene was 56\u2009ppb and 48\u2009ppb, respectively. The main finding was that TC showed higher transmission in the THz region producing a higher oxidative stress on the body.<jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/jbio202300120-gra-0001.png\" xlink:title=\"image\"\/><\/jats:p>","DOI":"10.1002\/jbio.202300120","type":"journal-article","created":{"date-parts":[[2023,6,1]],"date-time":"2023-06-01T13:28:53Z","timestamp":1685626133000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["<scp>NIR<\/scp> and <scp>THz<\/scp> spectroscopy: An experimental investigation toward nicotine\u2010related devices"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4407-0292","authenticated-orcid":false,"given":"Ana\u2010Maria","family":"Bratu","sequence":"first","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics  Bucharest PO Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0511-6152","authenticated-orcid":false,"given":"Mihaela","family":"Bojan","sequence":"additional","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics  Bucharest PO Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9675-2132","authenticated-orcid":false,"given":"Stefan","family":"Banita","sequence":"additional","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics  Bucharest PO Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5880-2477","authenticated-orcid":false,"given":"Mioara","family":"Petrus","sequence":"additional","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics  Bucharest PO Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3881-6956","authenticated-orcid":false,"given":"Cristina","family":"Popa","sequence":"additional","affiliation":[{"name":"National Institute for Laser, Plasma and Radiation Physics  Bucharest PO Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,6,9]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.3109\/03602539409029782"},{"key":"e_1_2_11_3_1","first-page":"33","volume":"8","author":"Margaritis V.","year":"2010","journal-title":"Oral Health Prev Dent"},{"key":"e_1_2_11_4_1","first-page":"53","volume-title":"IARC Monographs on the Evaluation of Carcinogenic Risks to Humans","author":"International Agency for Research on Cancer","year":"2004"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/ntr\/ntq216"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr200084z"},{"key":"e_1_2_11_7_1","first-page":"794","volume":"52","author":"Devasagayam T.
