If this is like an explanation with no "correct answer," here's my opinion.
Drugs can be used in resourceful ways to treat people from a certain disease or relieve pain but drugs can also be abused at times. An example of abusing drugs is buying and consuming illegal drugs without a prescription from a doctor or using drugs to harm others or even yourself. To conclude, the difference between using and abusing a drug is using a drug is usually for a good cause while abusing a drug is usually for a harmful or bad cause.
The difference between using and abusing a drug: using a drug can be helpful if you are in pain, need to fight a virus and etc, and then stopping. Abusing a drug is taking a drug after you’ve fixed the issue as to why you were taking the drug in the first place, abusing drugs can be addictive and dangerous.
