Paying for drug treatment can be a challenge, because typically all resources have been exhausted due to the persons drug habit. Many drug rehab programs recognize this fact which is why many drug rehab facilities across the nation offer 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 rehabilitation facilities would prefer to find a way to make it work financially so that those that need addiction help can acquire the help they need.
