Anfetimings, also known as amphetamines, are a class of stimulant drugs that affect the central nervous system. They increase the levels of certain neurotransmitters, particularly dopamine and norepinephrine, leading to enhanced alertness, concentration, and energy. Amphetamines are used in medical settings to treat conditions like ADHD and narcolepsy, but they can also be misused for their euphoric effects. Prolonged use can lead to dependency and various health risks.
