  • 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.
  • Dual Diagnosis/ Co-Occurring Disorders Treatment

    These two terms describe a person who is not only addicted to drugs or alcohol, but also has a mental or emotional illness, such as depression, anxiety, bipolar disorder, etc. Facilities that treat patients with dual-diagnosis or co-occurring disorders provide psychiatric treatment in addition to drug and alcohol rehabilitation services.
