Paying for drug or alcohol rehab can be a challenge, as all resources have been exhausted because of the persons drug habit. Many drug rehab programs understand this reality which is why many drug treatment facilities around the country offer payment options known as a sliding scale fee. There are many variables put into the equation of determining what the fee will be from person to person, and these factors are based on individual circumstances such as income, cash on hand, living circumstances, the size of one's family etc. Sliding scale fees have been in use for some time as most drug and alcohol rehabilitation programs would rather find a way to make it work financially so that those suffering with addiction can get the help they need.
