amphetamine
Amphetamine is a powerful central nervous system stimulant that increases the release of chemicals like dopamine and norepinephrine in the brain. This action boosts alertness, concentration, and energy levels, often used medically to treat conditions like ADHD and narcolepsy. However, it can also be misused recreationally, leading to dependence and adverse health effects such as increased heart rate, high blood pressure, and potential mental health issues. Its effects typically include heightened focus, euphoria, and decreased appetite, but misuse poses significant risks to physical and mental well-being.
