Then your old Phys-Ed book is woefully inaccurate to the point of ineptitude. I gave a direct quote from the OED, but here's another definition from the medical dictionary. You'll notice the parity between the two definitions:Realitycrash said:My old Phys-Ed book.catalyst8 said:I have no idea where you got that, but it isn't an English definition. The OED defines the noun 'Drug' as:Realitycrash said:A drug is defined as:
A physical substance:
A: that brings a rush.
B: that is hazardous to your health.
C: that is addictive.
So yes, Alcohol is a drug. A socially acceptable drug, because it's been around for ages.
If cigarettes were "invented" today, they would be banned as an illegal drug, make no mistake, and so would alcohol.
'a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body'
and
'a substance taken for its narcotic or stimulant effects, often illegally'.
"a substance taken for its narcotic or stimulant effects, often illegally" would make candy a drug, though.
Actually, in a very broad definition, candy would be covered by my definition as well, but it isn't hazardous or addictive "enough".
"1. a chemical substance that affects the processes of the mind or body.
2. any chemical compound used in the diagnosis, treatment, or prevention of disease or other abnormal condition.
3. a substance used recreationally for its effects on the central nervous system, such as a narcotic.
4. to administer a drug to."
And yes, sugar is most definitely a drug.
I find it absurd that a textbook would describe a scientific definition with "That brings a rush', or that it could be so incredibly wrong with insisting all drugs are "hazardous to your health" & "addictive". Penicillin is a very widely used drug, but fits none of your descriptions.
Would you be good enough to give me the title of the book from which you quoted your definition, please?
