For facial plastic surgeons, the clinical implications remain difficult to define because \u201ccannabis use\u201d encompasses heterogeneous products and routes, including smoked flower, vaping, concentrates, edibles, pharmaceutical cannabinoids, topical cannabidiol (CBD), and frequent co-use with tobacco or nicotine. Current evidence suggests that systemic cannabis use, particularly inhaled or heavy perioperative use, may be associated with increased surgical complications in selected populations; however, existing studies are limited by retrospective design, inconsistent exposure definitions, inadequate dose and route characterization, and confounding by tobacco use and comorbidities. Cannabinoids exert biologic effects through the endocannabinoid system, particularly CB1 and CB2 receptors, which are expressed in the central nervous system, immune cells, vasculature, and skin. These pathways influence inflammation, keratinocyte proliferation, fibroblast activity, angiogenesis, immune surveillance, pain signaling, and tissue remodeling. The net effect of cannabinoid exposure on wound healing is likely context dependent, varying based on receptor expression, wound-healing phase, route of administration, cannabinoid composition, local tissue environment, and patient-specific risk factors. Preclinical and early dermatologic literature suggests potential therapeutic roles for topical cannabinoids, especially CBD, in modulating inflammation and epithelial repair. In contrast, systemic perioperative cannabis use has been associated in several surgical cohorts with infection, delayed healing, hematoma, nonunion, and reoperation. Evidence specific to facial plastic surgery remains sparse. The most directly relevant study evaluated cannabis and tobacco use in patients undergoing operative mandibular fracture repair. Cannabis-only use was not associated with increased complications, although the cohort was small; concurrent cannabis and tobacco use was associated with higher rates of surgical site infection, facial nonunion, abscess, debridement, and malocclusion. To date, no published studies address cannabis-associated outcomes in rhinoplasty, rhytidectomy, blepharoplasty, browlift, or facial rejuvenation. This review summarizes the biologic rationale, available surgical evidence, and clinical considerations for incorporating cannabis use into individualized perioperative risk assessment in facial plastic surgery.<\/jats:p>","DOI":"10.3390\/jpm16090442","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T10:07:53Z","timestamp":1787566073000},"page":"442","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cannabis and Wound Healing: A Narrative Review of Current Evidence and Applications to Facial Plastic Surgery"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7679-0908","authenticated-orcid":false,"given":"Bita Rashed","family":"Naimi","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, University of California San Diego Health, San Diego, CA 92103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1000-3171","authenticated-orcid":false,"given":"David B.","family":"Hom","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, University of California San Diego Health, San Diego, CA 92103, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e2136571","DOI":"10.1001\/jamanetworkopen.2021.36571","article-title":"Sociodemographic characteristics associated with prevalence and frequency of cannabis use among adults in the US","volume":"4","author":"Jeffers","year":"2021","journal-title":"JAMA Netw.
