Will these drugs cause further damage?

[jb00]

Hi, I'm asking this since I'm concerned about a close relative. She has been diagnosed with cirrhosis stage 1 5 years ago, and doctors says she is doing well and that the liver function is good. Her tests are well says the doctors and she does not drink any alcohol.

I am not sure, but suspects that she has been using legal drugs such as synthetic cathinones (N ethyl hexedrone, methylphenidate) not very often but on multiple occasions as well as xanax. My question is if occasional use by itself will cause further damage to her liver. I understand that her liver has a slower metabolism or somewhat decreased function, but is using these substances something that will damage her liver cells further?

Thankful for your response.
