So is reusing toilet paper a bad thing? I used some already used toilet paper today because there weren't any other options. But it got me thinking if there is any problems with is. What happened I was on the toilet doing a shit and run out of paper half way through I called out to my sister to get me another roll from the other bathroom. She had just finished taking a piss and was in the process of wiping with the last of the toilet paper in the house.(good does she use some paper) she said she would give it to me she had to wipe first. So she wiped. Then gave it to me and it was damp all over and part was soaked through. So I had to choices not use it and be stuck for a few hour until a grocery deliver came wait for her to unpack it and give me some or use what was there. So I used it. Which has got me thinking I would save a lot of money using her pee covered toilet paper. Can anyone see any problems reason why not to?
