The difference between adults and teenagers are that adults pay bills. How do you think she pays bills so you can eat and have warm place to sleep. You can't compare yourself to your mom and say that if she does it it's ok. I personally didn't like pot until now. I couldn't concentrate when I smoked so I never liked it. Now I need it because my kids drive me crazzzzzzy. Having said that, she needs to be more responsible and keep drugs out of the your way. Kids brain are still changing while mine is just getting old and sad to say I'll will not grow any more new cells. Good Luck!!!
