• A substance that raises levels of physiological or nervous activity in the body.
Stimulants increase activity, interest, or enthusiasm in a specific field.
• Stimulants can be taken orally in pill form, inhaled nasally, smoked, or injected.
• Stimulants induce alertness, elevated mood, wakefulness, increased speech and motor activity and decrease appetite.

HOW DO STIMULANTS AFFECT THE BRAIN?
• Substances of abuse also affect the nucleus acumens by increasing the release of the neurotransmitter dopamine, which helps to regulate the feelings of pleasure. Dopamine plays an important role in the control of movement, cognition, motivation, and reward.
High levels of dopamine in the body improve mood and increase body movement.
However, too much dopamine may produce nervousness, irritability, aggressiveness, and paranoia that may cause schizophrenia, as well as the hallucinations and bizarre thoughts of schizophrenia. Too little dopamine in certain areas of the brain results in the tremors and paralysis of Parkinson's disease.
