In this study, participants ingested a cannabis-infused edible and provided breath samples before and at three timepoints after ingestion. Participants were assigned to one of two breath sampling devices. THC was found in most pre-use breath samples, and THC concentration had variable trends after ingestion. Nineteen participants exhibited a maximum in their THC concentration at 47, 92, or 180\u2009min after ingestion, while six participants had their highest THC concentration before the observed ingestion, and four participants had no significant change in THC concentration over the four samples. Five additional cannabinoids were detected in breath. While cannabidiol (CBD) trends followed THC trends for some participants, diverging trends in other participants suggest different biological processing of CBD derived from edibles. This proof-of-concept study shows that THC concentration in breath can increase after the ingestion of cannabis-infused edibles, but the uncertainty of breath measurements and a longer time window need to be further explored.<\/jats:p>","DOI":"10.1093\/jat\/bkaf063","type":"journal-article","created":{"date-parts":[[2025,7,10]],"date-time":"2025-07-10T15:45:25Z","timestamp":1752162325000},"page":"673-680","source":"Crossref","is-referenced-by-count":3,"title":["The detection of cannabinoids in breath after ingestion of cannabis-infused edibles"],"prefix":"10.1093","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1395-1062","authenticated-orcid":false,"given":"Jennifer L","family":"Bery","sequence":"first","affiliation":[{"name":"Applied Chemicals and Materials Division, National Institute of Standards and Technology , 325 Broadway Ave , Boulder, CO 80305,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashley","family":"Brooks-Russell","sequence":"additional","affiliation":[{"name":"Colorado School of Public Health, University of Colorado Anschutz Medical Campus , 13001 E. 17th Place , Aurora, CO 80045,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tara M","family":"Lovestead","sequence":"additional","affiliation":[{"name":"Applied Chemicals and Materials Division, National Institute of Standards and Technology , 325 Broadway Ave , Boulder, CO 80305,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kavita M","family":"Jeerage","sequence":"additional","affiliation":[{"name":"Applied Chemicals and Materials Division, National Institute of Standards and Technology , 325 Broadway Ave , Boulder, CO 80305,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,7,10]]},"reference":[{"key":"2026051508120103800_bkaf063-B1","doi-asserted-by":"crossref","first-page":"104433","DOI":"10.1016\/j.neubiorev.2021.11.004","article-title":"Are blood and oral fluid delta(9)-tetrahydrocannabinol (THC) and metabolite concentrations related to impairment?
