Paying for drug or alcohol rehab can be a challenge, as all resources have been exhausted because of their addiction. Many drug treatment facilities understand this reality which is why many drug rehabilitation programs around the country offer payment options known as a sliding scale fee. There are various 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 treatment programs would prefer to find a way to make it work financially so that those that need addiction help can receive the help they need.
