Paying for drug or alcohol rehab can be a problem, as all resources have been exhausted because of their drug habit. Many drug rehab facilities recognize this fact which is why many drug rehab programs across the nation offer payment arrangements known as a sliding scale fee. There are several 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 rehab facilities would rather find a way to make it work financially so that those suffering with addiction can acquire the help they need.
