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.

A general surgeon is a medical professional who performs surgery on patients. General surgeons typically perform common surgeries and have attended college and medical school to learn the skills needed to perform them successfully. They also care for their patients before and after operations and can give an accurate prognosis after the surgery is complete and the patient has had time to heal.
