Paying for drug rehab can be a challenge, as all resources have been exhausted due to the persons addiction. Many drug rehab programs recognize this reality which is why many drug rehab facilities around the country provide payment options known as a sliding scale fee. There are various 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 facilities would rather find a way to make it work financially so that those suffering with addiction can receive the help they need.
