Which major drug class includes amphetamines and methamphetamines?

The major drug class that includes amphetamines and methamphetamines is stimulants. Stimulants are substances that increase alertness, attention, and energy by elevating the levels of key neurotransmitters in the brain, particularly dopamine and norepinephrine. Amphetamines, for example, are often prescribed for conditions like ADHD and narcolepsy. They work by increasing the concentration of these neurotransmitters, which enhances focus and energy levels.

Methamphetamines, a more potent form of amphetamines, have significant effects on the central nervous system and can lead to heightened energy, alertness, and euphoria. However, they also carry a high potential for abuse and addiction, which is often associated with severe physical and psychological consequences. This highlights the powerful stimulant properties of both amphetamines and methamphetamines, which distinguish them from other drug classes like depressants, analgesics, and hallucinogens.

Understanding these classifications is essential for recognizing the effects and risks associated with different substances, particularly in a clinical or therapeutic context.
