Paying for drug 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 rehab facilities across the nation offer 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 rehabilitation programs would rather find a way to make it work financially so that those that need addiction help can receive the help they need.
