A study has found that patients with chronic hepatitis C virus (HCV) who use cannabis have a lower risk of obesity and central obesity. The study, which analyzed data from the French ANRS CO22 Hepather cohort, used logistic regression models to examine the inverse relationship between cannabis use and body weight in HCV patients. The results showed that current cannabis use was associated with a lower risk of central obesity, BMI-based obesity, and overweight. This relationship was also observed in former cannabis use but to a lesser extent. The study suggests that cannabis use may be a factor in reducing obesity in HCV patients, but further research is needed to confirm these findings.
