The cohort consisted of 20,558 patients with cancer aged 18 and older with a chemotherapy claim in an outpatient setting within 12 months of a cancer diagnosis. Exposure was a registration to receive an MMJ card that permitted access to MMJ. The primary outcome of interest was antiemetic overuse, as characterized by the ASCO recommendation. Antiemetic use associated with chemotherapy was identified through filled prescriptions and medical claims. Multivariable logistic regression, adjusted for baseline demographic and prescription characteristics, was used to calculate the adjusted odds ratios (aOR) of antiemetic overuse among MMJ cardholders compared with non-MMJ cardholders.</p><p><strong>Results: </strong>Among 20,558 eligible patients, 436 (2.1%) had an MMJ card at some point in the study period.

Arterialized-venous blood was collected prior to, during (including the last minute of exercise), and 15 min following exercise for determination of anandamide concentration. The subjective experiences of the participants during and after the run were assessed with responses to several questions assessed on a Likert scale.</p><p><strong>Results: </strong>Compared with controls, the cannabis use group had lower AEA concentrations at end-exercise (0.47 ± 0.13 vs. 0.33 ± 0.10 ng/mL; <i>p</i> = 0.015) and 15-min post-exercise (0.57 ± 0.17 vs. 0.38 ± 0.18 ng/mL; <i>p</i> = 0.001). The cannabis use group also had worse mood (3.25 ± 1.03 <i>vs.</i> 2.29 ± 1.34; main effect of condition <i>p =</i> 0.05) and higher probability of feeling pain (<i>p</i> < 0.001).</p><p><strong>Conclusion: </strong>Habitual cannabis use was associated with diminished AEA response, worse mood, and more pain during/following exercise. These pilot data might have implications for clinical outcomes associated with cannabis use, including cannabis use disorder and withdrawal, as well as potentially for exercise adherence.</p>","PeriodicalId":9386,"journal":{"name":"Cannabis and Cannabinoid Research","volume":" ","pages":"25785125261428008"},"PeriodicalIF":2.7,"publicationDate":"2026-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147316118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
