Paying for drug or alcohol rehabilitation can be a problem, as all resources have been exhausted because of the persons drug habit. Many drug rehab facilities recognize this reality which is why many drug treatment facilities around the country provide payment options known as a sliding scale fee. There are many 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 rehab facilities would prefer to find a way to make it work financially so that those that need addiction help can receive the help they need.
