This is not correct. Studies have clearly shown that if you give someone a moderate dose of ranitidine, the NDMA levels in their urine skyrocket. upwards of 400 times higher if I remember correctly. This is higher than in people who have bladder cancer due to schistosomiasis, a disease causing increased levels of NDMA in the body.

There are somatic processes, likely starting in the stomach and concluding in the liver, which are efficiently converting ranitidine to NDMA. Here's just one study. https://academic.oup.com/carcin/article/37/6/625/1744630
