The diverse drug and alcohol abuse treatment services which are accessible to drug addicted people in Mount Vernon can vary in a lot of various ways. Some substance abuse rehabilitation services take place in a residential or inpatient setting, where clients reside the entire time they are in rehabilitation which offers a more therapeutic treatment environment. Others offer substance abuse treatment programs on an outpatient basis which allows for more flexibility, though outpatient programs may not be a suitable alcohol and drug abuse rehabilitation service for individuals in Mount Vernon who are struggling with serious addiction problems. Regardless of whether inpatient or outpatient substance abuse rehabilitation programs are selected, there are varying amounts of time that people will be asked to stay in the drug and alcohol rehabilitation facility. For example, quite a few short-term programs offer programs for 4 weeks or less, while long-term facilities will demand at least a 3 month stay.
