  • Residential Treatment

    Residential treatment programs provide housing (food and meals) in addition to treatment for substance abuse. Some facilities offer only short-term residential treatment, some offer only long-term treatment and others offer both, ranging from a few days to many months, based on patient needs.
  • Medical Detoxification

    Drugs and alcohol have widespread effects throughout your body, including but not limited to the addiction and/or physical/psychological dependence that develops with substance abuse over time. Many organ systems are affected by addiction and will react to withdrawal. The term “medical detoxification” means that there is a trained and licensed medical professional onsite to monitor your vital signs and protect your physical and emotional health as your body goes through withdrawal.
