Which category of drugs includes methamphetamine?

Methamphetamine is classified as a stimulant due to its effects on the central nervous system. Stimulants are substances that increase brain activity, leading to heightened alertness, increased energy, and elevated mood. Methamphetamine specifically enhances the release of dopamine, a neurotransmitter associated with pleasure and reward, which contributes to its high potential for addiction and abuse.

In contrast, opioids are primarily pain-relieving medications that work on opioid receptors in the brain, producing effects that include pain relief and euphoria. Benzodiazepines are used mainly to treat anxiety and insomnia and function by depressing the central nervous system to promote relaxation and sedation. Alcohols, commonly known recreational substances, are also depressants that slow down brain function and metabolic processes.

By understanding that methamphetamine acts as a powerful stimulant, one can recognize its distinct pharmacological profile compared to other categories of drugs.
