Which drug classification includes drugs such as cocaine and amphetamines?

The classification that includes drugs such as cocaine and amphetamines is CNS stimulants. This category is characterized by substances that increase the activity of the central nervous system (CNS), leading to heightened alertness, increased energy, and elevated mood.

Cocaine and amphetamines specifically are known for their ability to enhance the release and inhibit the reuptake of neurotransmitters like dopamine and norepinephrine, which results in increased levels of these chemicals in the brain. This leads to the stimulating effects that users experience, such as increased wakefulness and improved concentration.

Each of the other classifications does not encompass the stimulating effects seen in cocaine and amphetamines. CNS depressants, for instance, lower brain activity, anti-psychotics primarily target psychotic symptoms and may have a calming effect, while non-barbiturates might refer to sedative-hypnotic drugs that also act as CNS depressants but do not include stimulants like cocaine and amphetamines. Thus, the classification of CNS stimulants accurately represents the pharmacological effects of these substances.
