Paying for drug or alcohol rehab can be a challenge, as all resources have been exhausted because of their drug habit. Many drug treatment facilities understand this reality which is why many drug and alcohol treatment facilities around the country offer payment options 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 treatment programs would rather find a way to make it work financially so that those that need addiction help can get the help they need.
