I was steered away from Repti Bark because I got the impression it could be hazardous to the snake. Any truth to that?

My kid begged for a snake since she was 7 years old. We didn't give in until she was 13. She's capable of doing better care but needs some better instruction. Part of the problem is that she is a teen who knows I'm a crazy lady (who never owned a reptile before) so she assumes I'm a paranoid crazy lady about my standards when I try to tell her how to take better care of the bp. It will really help her take me seriously when the forum backs me up on something like not letting the aspen stay WET under his hide, etc. I did read many books about the bp to ensure I could oversee his proper care.
