or mixture of substances manufactured, sold or represented
for use in
- the diagnosis, treatment, mitigation or prevention of a disease, disorder, abnormal physical state, or symptoms thereof, in man or animal

Other definitions include
, "anything that enters into the body and affects its functioning or some part of it in some way". "A drug, affects the body, mind or perceptions and changes the way a body works".
Although an apple changes the body by providing nutrients, these nutrients are required to function correctly, and do not alter in any large way the body's metabolism. A drug would, whilst active, change some function of the body (for better or worse), provide a perception shift etc. A drug is effectively a non-essential product that the body takes in for its own good, or that the body takes in for the mind's pleasure/expansion.
The difference between food and drugs is quite clear. Some foods contain drugs, or are also drugs. For example,chocolate.
