Compared to weight-based taxation, potency-based taxes (i.e., THC) were associated with a 30%-32% increase in cannabis quantity consumption.

At our Institution, we implemented a protocol for early transfer at HaH for kidney transplant recipients (KTR) starting from post-operative day 4.

Furthermore, illicit drug use was associated with a significant reduction in SF-6D utility values (β = -0.022, 95% CI: -0.026, -0.018), highlighting the adverse impact on overall HRQoL among adults. Illicit drug use was associated with reduced MCS scores and SF-6D utility values across genders and age groups, with greater reduction among young adults aged 15-29 years [(MCS = -2.30, 95% CI: -2.92, -1.68) and (SF-6D = -0.021, 95% CI: -0.027, -0.015)], and male drug users [(MCS = -2.46, 95% CI: -2.93, -1.99), and (SF-6D = -0.021, 95% CI: -0.026, -0.016)].</p><p><strong>Conclusion: </strong>The study findings confirmed that individuals who use illicit drugs experience significantly lower HRQoL than their peers. Additionally, the study provided a specific disutility value for illicit drug use, offering crucial data for future evaluations of the cost-effectiveness of drug harm reduction programs.</p>","PeriodicalId":51416,"journal":{"name":"European Journal of Health Economics","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148609995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
