There were concerns about how the pandemic affected substance use in the population. The overall objective of this study was to assess whether COVID-19 Stay-At-Home (SAH) orders, an ambient ecological stressor, as well as the severity of depressive and anxious symptoms, can explain tobacco and marijuana use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data come from the first seven waves of the Understanding America Study, a nationally representative longitudinal web-based panel study. A total of 7,554 persons participated in the first seven waves, resulting in 43,582 observations. Cigarette use as a measure was not included until wave four of the study; 7,034 persons participated in waves four through seven, resulting in 24,893 observations. The primary outcomes were self-reported past seven-day use of cigarette products and past seven-day use of marijuana products. Self-reported depressive and anxious symptom severity, the proposed mediator, was measured using the Patient Health Questionnaire-4 (PHQ-4). The primary exposure was a binary indicator for the presence of an SAH order. All variables were measured biweekly. Generalized Estimating Equations (GEE) were used to assess single-mediator models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Persons under SAH orders had 2.18 (95% CI: 1.27, 3.73) times the odds of moderate-to-severe depression across the first seven waves, relative to those living in states without SAH orders. Those with moderate-to-severe depression and anxiety had lower odds of both marijuana (OR = 0.37, 95% CI: 0.17, 0.84) and cigarette use (OR = 0.29, 95% CI: 0.13, 0.65) compared to those with normal-mild PHQ-4 scores. Worsened mental health within a person resulted in 0.22 (95% CI: 0.12, 0.40) times the odds of marijuana use and 0.26 (95% CI: 0.15, 0.47) times the odds of cigarette use. Tests of the joint effects suggest evidence of multiple mediated pathways.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1371\/journal.pone.0337996","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T18:43:59Z","timestamp":1764960239000},"page":"e0337996","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Depression and anxiety mediate the relationship between COVID-19 stay-at-home orders and tobacco and marijuana use"],"prefix":"10.1371","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0894-3006","authenticated-orcid":true,"given":"Geoffrey","family":"Carney-Knisely","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jolynn","family":"Pek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy K.","family":"Ferketich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tasleem J.","family":"Padamsee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamar","family":"Gur","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parvati","family":"Singh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2025,12,5]]},"reference":[{"issue":"15","key":"pone.0337996.ref001","doi-asserted-by":"crossref","first-page":"451","DOI":"10.15585\/mmwr.mm6915e2","article-title":"Timing of community mitigation and changes in reported COVID-19 and community mobility -
