Paying for drug treatment can be a challenge, as all resources have been exhausted because of their drug habit. Many drug treatment facilities understand this fact which is why many drug rehab programs across the nation provide payment options 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 rehab facilities would prefer to find a way to make it work financially so that those suffering with addiction can get the help they need.
