Medicaid is a health insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether an individual qualifies for Medicaid doesn't only determined by income however, and people shouldn't assume they don't qualify simply because they make a reasonable income. For example, people who have a lot of dependents may qualify for Medicaid regardless of whether they earn what would be described as a sensible income. Medicaid may also cover the price of rehabilitation, when someone has been abusing alcohol or drugs and needs treatment. There are many drug rehabilitation facilities which accept Medicaid, but various states have different rules for what forms of treatment are covered. Some states only include outpatient rehabilitation services for example while other states cover more intensive rehabilitation like a residential stay in long-term drug rehabilitation center. If anyone is involved in drug abuse and needs help, they can use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid plus don't have the cash or another kind of health care insurance to cover treatment, they can see if they are eligible for a Medicaid and then sign up for an alcohol and drug rehabilitation program that's approved inside their state.
