Now with an additional legal access system designed for nonmedical purposes, it is unclear what factors influence cancer survivors\u2019 decisions to medicate or not medicate cannabis as a complementary therapy to alleviate their cancer symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We recruited cancer survivors via social media. Interested individuals were purposively sampled to ensure maximization in terms of age, sex, and province of residence. Constructs of the Theory of Planned Behavior were explored during the telephone interviews as participants described what influenced their decisions to medicate or not medicate cannabis to manage their symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Interviews were conducted with 33 cancer survivors. All individuals believed that cannabis would manage their cancer symptoms. Those that chose to medicate with cannabis provided a variety of reasons, including that cannabis was a more natural alternative; that it reduced their overall number of prescription drugs; and that safer products had become available with the legalization of nonmedical cannabis. Some individuals also indicated that support from physicians and validation from family and friends were important in their decision to medicate with cannabis. Individuals who opted not to medicate with cannabis raised concerns about the lack of scientific evidence and\/or possible dependency issues. Some also felt their physician's disapproval was a barrier to considering cannabis use.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings revealed that recreational legalization made using cannabis appear safer and easier to access for some cancer survivors. However, physicians\u2019 censure of cannabis use for symptom management was a barrier for survivors considering its use.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cam4.3536","type":"journal-article","created":{"date-parts":[[2020,10,17]],"date-time":"2020-10-17T13:16:16Z","timestamp":1602940576000},"page":"396-404","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Understanding cancer survivors\u2019 reasons to medicate with cannabis: A qualitative study based on the theory of planned behavior"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5451-0845","authenticated-orcid":false,"given":"Helen","family":"McTaggart\u2010Cowan","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences Simon Fraser University Canadian Centre for Applied Research in Cancer Control Cancer Control Research, BC Cancer Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colene","family":"Bentley","sequence":"additional","affiliation":[{"name":"Canadian Centre for Applied Research in Cancer Control Cancer Control Research, BC Cancer Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Raymakers","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences Simon Fraser University Canadian Centre for Applied Research in Cancer Control Cancer Control Research, BC Cancer Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Metcalfe","sequence":"additional","affiliation":[{"name":"Cancer Control Research, BC Cancer School of Population and Public Health, University of British Columbia Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippa","family":"Hawley","sequence":"additional","affiliation":[{"name":"Pain &amp; Symptom Management\/Palliative Care Program BC Cancer Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart","family":"Peacock","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences Simon Fraser University Canadian Centre for Applied Research in Cancer Control Cancer Control Research, BC Cancer Vancouver BC Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,10,17]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198507253130421"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11912-019-0757-7"},{"key":"e_1_2_9_4_1","volume-title":"The health effects of cannabis and cannabinoids: the current state of evidence and recommendations for research","author":"The National Academies of Sciences, Engineering, and Medicine","year":"2017"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.21037\/apm.2017.08.05"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctim.2019.102204"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/13543784.2019.1561859"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1155\/2001\/469629"},{"key":"e_1_2_9_9_1","unstructured":"Health Canada.Understanding the New Access to Cannabis for Medical Purposes Regulations Canada: Government of Canada;2016[cited 2019 3 February].
