GPT and metabolic dysfunction-associated steatotic liver disease: Kim et al. conducted an observational study and found that active marijuana use protected against NAFLD through serum alanine aminotransferase levels (n = 14080, OR: 0.76; 95% CI: 0.58–0.98, P = 0.001 for current light users; OR: 0.70; 95% CI: 0.56–0.89, P = 0.001 for current heavy users) and ultrasound diagnosis (n = 8286, OR: 0.77, 95% CI: 0.59–1.00, P = 0.053 for current users; OR: 0.71, 95% CI: 0.51–0.97, P = 0.033 for current light users [25].
