To become a counselor, you will most likely need to get a post-bachelor's degree from an accredited school. Drug and alcohol abuse counselors usually only need to receive an associate's degree. Once you have your degree, you will need to have at least 2 years of field experience to get your certification from the state. The annual salary ranges from $25,000 - $58,000.
