Paying for drug rehabilitation can be a challenge, as all resources have been exhausted due to their addiction. Many drug rehab programs fully grasp this reality which is why many drug rehabilitation facilities around the country offer payment options known as a sliding scale fee. There are several 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 rehab programs would rather find a way to make it work financially so that those suffering with addiction can get the help they need.
