What are the steps involved in treating a drug or substance addiction?

1. Realize that you have a problem and that you need to set change
2. Schedule doctor, pharmacist, or rehab programs to help you
3. Try getting support from your family, friends, or other sober people that you know
4. Once you are out of drug or substance use, maintain that position by starting a new hobby, or replacing drug use with something else like a job or sports.
