Firstly, we demonstrated that the solution of the model is a bounded region and nonnegative, which demonstrated that the model is well posed both mathematically and epidemiologically. Besides, we computed the cigarette smoking\u2013free equilibrium and the endemic equilibrium points of the model. Then, the basic reproduction number was computed using the next\u2010generation matrix, and the stability analysis of the equilibrium points was examined. The analysis shows that the cigarette smoking\u2013free equilibrium point is stable over time if the basic reproduction number is less than one; otherwise, the model will reach the endemic equilibrium point. Also, a sensitivity analysis was conducted to assess the impact of key factors on cigarette smoking dynamics. Moreover, we extended the cigarette smoking dynamics model to an optimal control model via two controls: educating individuals and treating addicted smokers. Then, the existence of optimal controls is proven, and using Pontryagin\u2019s minimum principle, the essential conditions of the optimal control model are examined. Also, if the resource is limited, a cost\u2010effectiveness analysis is considered to identify the least costly strategies. Finally, the numerical simulation of optimality systems concluded that educating individuals to keep them away from the smoking addiction population is the most effective strategy to lessen the addiction of cigarette smoking.<\/jats:p>","DOI":"10.1155\/jama\/7486539","type":"journal-article","created":{"date-parts":[[2025,7,17]],"date-time":"2025-07-17T17:34:02Z","timestamp":1752773642000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Optimal Control Analysis of Smoking Dynamics Model With Cost\u2010Effective Strategies"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1217-6631","authenticated-orcid":false,"given":"Beza Zeleke","family":"Aga","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6869-852X","authenticated-orcid":false,"given":"Temesgen Duressa","family":"Keno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Debela Etefa","family":"Terfasa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8362-7612","authenticated-orcid":false,"given":"Mo\u2019tassem","family":"Al-arydah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,17]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1988.319"},{"key":"e_1_2_12_2_2","volume-title":"WHO Global Report on Trends in Prevalence of Tobacco Use 2000-2030","author":"World Health Organization","year":"2024"},{"key":"e_1_2_12_3_2","volume-title":"A Mathematical Model for Lung Cancer: The Effects of Second-Hand Smoke and Education","author":"Summerville E.
