The Difference Between Drug and Medicine
From chemistry point of view, there is no distinction between the terms drugs and medicines, i.e., all drugs are medicines and all medicines are drugs. However, our society and law make a clear-cut distinction between these two terms as follow:
A medicine is a chemical substance which cures the disease, is safe to use, has negligible toxicity and does not addiction. In contrast, a drug is a chemical substance which also cures the disease but is habit forming, causes addiction and has serious side effects.
