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