“The prevalence of Clostridioides difficile Infection (CDI), the most notorious hospital acquired disease, and of excessive cannabis use (cannabis use disorder (CUD)) have both been steadily rising.
Although cannabidiol, an active ingredient of cannabis, maintains gut integrity and suppresses entero-toxins from Clostridioides difficile, the relationship between CUD and CDI has not been studied.
Among the matched hospitalizations (n = 59,824), cannabis usage was associated with a reduced prevalence of CDI (prevalence: 455.5 [95% CI: 385.1-538.8] vs. 636.4 [95% CI: 549.9-736.5] per 100,000 hospitalizations), resulting in a 28% reduced risk of CDI (relative risk: 0.72 [95% CI: 0.58-0.88]; p = 0002). Non-dependent and dependent CUD respectively had 23% and 80% reduced likelihood of CDI when compared to non-cannabis users (0.77 [95% CI: 0.60-0.95] and 0.20 [95% CI: 0.06-0.54]; p < 0.05). Furthermore, dependent users had less risk of CDI compared to non-dependent users (0.26 [95% CI: 0.08-0.88]; p = 0.01).
CUD was associated with a decreased risk of CDI amongst hospitalized patients. Prospective and molecular mechanistic studies are required to elucidate how cannabis and its contents impacts CDI.”
“Cannabis use was associated with diminished risk of Clostridioides difficile (CDI) amongst hospitalized individuals. Dependent Cannabis users seemed to be the most protected from CDI.” https://www.sciencedirect.com/science/article/pii/S1075996419301556?via%3Dihub
