Is CBD oil safe for the liver?

Can you provide some insight on the safety of CBD oil for the liver? There have been mixed opinions on whether it poses any risks to liver health, and I'm interested in understanding the current scientific consensus on this topic. Are there any long-term studies that have been conducted to evaluate the potential effects of CBD oil on liver function? Additionally, are there any specific groups of people, such as those with pre-existing liver conditions, who should avoid using CBD oil altogether?
