Paying for drug rehab can be a challenge, as all resources have been exhausted due to the persons addiction. Many drug treatment programs understand this fact which is why many drug and alcohol treatment facilities across the nation offer 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 rehabilitation facilities would rather find a way to make it work financially so that those suffering with addiction can get the help they need.
