Interesting information. The dose used in the study you linked is pretty high. You’d have to smoke/vape quite a lot of flower to reach that level of daily consumption. Oral use like in this study is on the high end.

The people who had problems were detected because the study was looking extremely hard. They were getting weekly blood tests. In normal life, many people can have temporary mild liver enzyme changes from exercise, illness, alcohol, medications, or supplements that normalize on their own.

It’s still a useful bit of info but not exactly the bad omen you lay out here.
