I have to agree with Cat.
This may sound harsh, but your mother couldn't handle you so she sent you to your father in hopes that he could. While you paint a pretty picture about being the perfect daughter, it is glaringly apparent to this of us who are parents that you are not. We can tell by your posts alone.
It is time for tough love and your dad is doing just that. In the grand scheme of things one month is nothing considering your drug use and the method you used to obtain those drugs.
If you want some semblance of freedom, you need to face your punishment. Pay the piper so to speak.
Suck it up my young friend, what you did was not only unethical, but illegal. You could be in far worse conditions than this. Consider yourself lucky.
