Paying for drug rehab can be a challenge, as all resources have been exhausted due to their addiction. Many drug rehab programs understand this fact which is why many drug and alcohol rehabilitation facilities around the country provide payment arrangements 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 and alcohol rehab facilities would rather find a way to make it work financially so that those that need addiction help can acquire the help they need.
