Cocaine is classified as a stimulant because it primarily acts on the central nervous system to increase alertness and energy levels. It enhances the activity of neurotransmitters such as dopamine, leading to heightened feelings of euphoria and increased energy. Stimulants, like cocaine, elevate mood, increase heart rate, and boost energy, which can result in users experiencing increased confidence and sociability. This classification is important in understanding the effects and risks associated with cocaine use in a social work or clinical context, particularly when considering its potential for addiction and impact on mental health.

In contrast, a hallucinogen alters perception and can lead to hallucinations or altered states of consciousness, while depressants slow down the central nervous system and can lead to sedation and reduced anxiety. Narcotics, often associated with pain relief, can have sedative effects but are fundamentally different as they typically target the opioid receptors in the brain. This distinction is critical in the context of substance use and its implications for treatment and intervention in social work practice.
