Paying for drug rehab can be a challenge, because typically all resources have been exhausted because of their addiction. Many drug treatment programs recognize this reality which is why many drug rehabilitation facilities around the country provide payment arrangements known as a sliding scale fee. There are several variables 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 that need addiction help can receive the help they need.
