Addiction medicine deals with patients suffering from a wide variety of addiction problems. It aims to free people from their addictions while providing support, counseling, and mental health services. Medical professionals who work in addiction medicine can help patients work through the detoxification process as well as provide harm reduction tactics and rehabilitation services. They may also treat conditions like hepatitis and HIV, which are related to addiction issues. This type of medicine is often associated with public health.

Psychiatrists are doctors who specialize in treating mental, addictive, and emotional disorders. They order diagnostic tests, prescribe medications, and use psychotherapy to help patients and their family members deal with these disorders and diseases. They often work with other doctors and specialists to help come up with the best treatment option for their patients.
