My mom keeps making excuses and won't listen to me?

I think the best thing to do, is not give a ****.. Your mom will do what is needed. Take action for things in your control, if you have a piggy bank or something (lock it up in safe). If he does drugs tell him to do it away from house. If he doesn't listen, let your mom handle it.. if she doesn't then this will give you all the inspiration you need to get out on your own and live the complete opposite, you control your own life. For now I wouldn't give I damn if I were you.. relax if you can.
