Answer:
A. The improper use of a drug for medical purposes
Explanation:
A person abuses drugs when taking illegal drugs or when taking medications in a way that is not recommended by the doctor or manufacturer. This abuse can lead to physical or psychological dependence.
Physical dependence means that the body is so used to a drug that it has physical symptoms of lack when the person stops taking it.
A person with psychological dependence takes the drug because it forms a large part of their life, and the person takes it to feel good. You may find that you cannot stop taking it. Some drugs have psychological and physical symptoms.
The more you consume, the more the body becomes tolerant to the substance, and therefore ceases to have a strong effect, which forces it to take larger amounts.
