Physical dependence

The so-called physical dependence is also called physical dependence or physiological dependence. It is a state of dependence on drugs caused by long-term and repeated use of drugs. The main manifestation is that the body must be maintained under a sufficient amount of drugs in order to maintain a normal state. Once the drug is stopped, the body's physiological and biochemical processes will produce a series of abnormalities and disorders, such as withdrawal syndrome.
