<human>: Give me a shortened version of the text

Hello well first of all I am almost in tears writing this so my sister A is 16 and a couple months ago my older sister P and her wife found out that she was smoking pot. now they choose not to tell my mom and punished A. They took away her phone so she only had it when she was at school but, a few weeks later P found out that A lied to all of us said she was going to work and ended up going to a park and smoking now we live in California it is not legal. So the next day P found the texts told A she was going to tell our mom and then A left with out telling anyone. We found her right as my mom got off work so they called her and told her on the phone. When my mom got home she punished A physically and at the end she was shaking and crying and so was my mom. 

Now I thought that would be the end of it but its not today my sister found out that not only is she still smoking she is cutting summer school which she needs to pass if she is going to graduate next year but also sending nudes and sneaking out. Now my parents are separated and my mom didn't tell my dad but they just went to his house to tell him. Reddit what can i do to get through to my sister. She is ruining her chances and breaking my moms heart.
