Paying for drug or alcohol rehabilitation can be a challenge, because typically all resources have been exhausted because of the persons drug habit. Many drug rehab facilities understand this fact which is why many drug and alcohol rehabilitation programs 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 treatment programs would prefer to find a way to make it work financially so that those that need addiction help can get the help they need.
