Answer:
The correct answers are "stimulants; depressants".
Explanation:
Stimulants are a type of drugs that when applied, one or more activities in the body are increased, including behavior and mental activity. Three classic examples of stimulant drugs are methamphetamine, cocaine and methylphenidate. On the other hand, depressants have the opposite effect in the body and result in reducing the activity of one or more areas of the brain. Benzodiazepines and barbiturates are examples of depressant drugs.
