This question has been answered may times and you need to do what the sujestions everyone has given you. This is not a simple thing here, nothing can be done overnight, there has to be some kind of proof to file a modivacation for custody, the court would have to be the one to order the custodial parent to take a drug test, and the court needs a reason to order this, more than just hear say, the courts also have rules to follow. If you do not want to take th advise that everyone gives to help you, then you neeed to consult with an attorney.
