Paying for drug or alcohol rehabilitation can be a problem, as all resources have been exhausted due to their drug habit. Many drug rehab facilities fully grasp this fact which is why many drug and alcohol rehabilitation programs across the nation provide payment arrangements known as a sliding scale fee. There are several factors 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 rehabilitation programs would prefer to find a way to make it work financially so that those that need addiction help can receive the help they need.
