What are stimulants often referred to as?

Stimulants are often referred to as "uppers" because they increase alertness, attention, and energy levels. The term "speed" is commonly associated with certain stimulant drugs, such as amphetamines, which can produce euphoric effects and heightened activity. By enhancing the release of neurotransmitters like dopamine and norepinephrine, stimulants can cause increased heart rate, improved mood, and heightened levels of arousal, making them distinct from other categories of drugs that have depressant or hallucinogenic effects. Understanding the classification of stimulants as "uppers" is essential, particularly in the context of their potential for abuse and the physiological effects they induce on the body and mind.
