Being eligible for Medicaid is not easy and only a certain group of those who meet the specifications are provided this form of insurance. Nationally, Medicaid is only offered to only low-income families or individuals who fall into their state's brackets of low-income eligibility. Each state determines its own rules of eligibility.

Often times, the addicted individual will still be responsible for a share of the cost or co-payment for the substance abuse treatment they receive.
