What type of drug are cocaine, amphetamine, and caffeine classified as?

Cocaine, amphetamine, and caffeine are classified as stimulants because they increase the activity of the central nervous system, leading to heightened alertness, energy, and often increased heart rate. These substances work primarily by enhancing the effects of neurotransmitters such as dopamine and norepinephrine in the brain, which can result in elevated mood and increased physical energy.

This classification is crucial in addiction studies and treatment approaches since stimulants can have various psychological and physiological effects on individuals, influencing both their behavior and overall health. Understanding the stimulating properties of these drugs is fundamental for professionals working in addiction recovery and mental health settings.
