One of the most effective ways to reduce tobacco use is to increase the prices of tobacco products. Minimum floor price laws (MFPLs) are a relatively new but more feasible strategy that sets a price below which the product cannot be sold. We aim to examine the effects of minimum floor prices (MFPs) on tobacco use among youth in Virginia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>An agent-based modelling (ABM) was developed from bottom-up to evaluate the influence of increasing the cigarette MFPs on middle and high school students smoking behaviour in the state of Virginia. A rational-addiction model was integrated to model the smoking decision of youth under the dynamic utility maximisation framework within the ABM.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The model predicted that every 10% increase in the MFP in Virginia could prevent 2232 8th graders and 1890 12th graders from cigarette smoking, a 2.4% and 1.8% reduction in median smoking prevalence. For students who smoked, 8th and 12th graders would consume 0.36 and 0.45 fewer cigarettes per smoking day if experiencing a 10% increase in the MFP from the baseline US$7.50 to US$8.30. The MFP level that produces the maximal response was estimated to be between 10% and 30%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>MFPLs provide local jurisdictions with a potentially effective strategy to reduce tobacco use and mitigate-related harms among youth.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/tc-2024-058801","type":"journal-article","created":{"date-parts":[[2025,4,5]],"date-time":"2025-04-05T04:17:51Z","timestamp":1743826671000},"page":"375-381","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Assessing the effects of minimum floor price laws on tobacco use among youth in the state of Virginia, USA: an agent-based simulation approach"],"prefix":"10.1136","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4688-1424","authenticated-orcid":false,"given":"Shuo-Yu","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Health Administration and Policy, George Mason University, Fairfax, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hemant","family":"Purohit","sequence":"additional","affiliation":[{"name":"Department of Information Sciences and Technology, George Mason University, Fairfax, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randy","family":"Koch","sequence":"additional","affiliation":[{"name":"Department of Psychology and the Center for the Study of Tobacco Products, Virginia Commonwealth University, Richmond, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew J","family":"Barnes","sequence":"additional","affiliation":[{"name":"Department of Health Behavior and Policy, Virginia Commonwealth University, Richmond, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rashelle B","family":"Hayes","sequence":"additional","affiliation":[{"name":"Psychiatry, Virginia Commonwealth University, Richmond, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoquan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Communication, George Mason University, Fairfax, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Xue","sequence":"additional","affiliation":[{"name":"Department of Health Administration and Policy, George Mason University, Fairfax, Virginia, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,4,4]]},"reference":[{"key":"2026050704350888000_35.3.375.1","doi-asserted-by":"crossref","first-page":"e850","DOI":"10.1016\/S2214-109X(20)30221-7","article-title":"Association of childhood smoking and adult mortality: prospective study of 120 000 Cuban adults","volume":"8","author":"Thomson","year":"2020","journal-title":"Lancet Glob Health"},{"key":"2026050704350888000_35.3.375.2","unstructured":"National Center for Chronic Disease P, Health Promotion Office on S, Health .
