stimulant drugs
Stimulant drugs are substances that increase activity in the central nervous system, leading to heightened alertness, energy, and feelings of euphoria. They work by boosting levels of certain brain chemicals like dopamine and norepinephrine, which can improve focus and reduce fatigue. Common stimulants include medications for ADHD (like Adderall), recreational drugs (like cocaine), and caffeine. While they can have therapeutic benefits, misuse or overuse can cause side effects such as increased heart rate, anxiety, and dependency. Proper medical supervision is essential to ensure safe use and to minimize risks.
