Paying for drug rehabilitation can be a challenge, because typically all resources have been exhausted due to the persons drug habit. Many drug rehab facilities understand this fact which is why many drug treatment facilities across the nation provide payment options known as a sliding scale fee. There are many 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 treatment programs would prefer to find a way to make it work financially so that those suffering with addiction can acquire the help they need.
