Question

a stimulant is a what causing substance

Answer 1

A stimulant is a type of substance that increases activity in the central nervous system, leading to heightened alertness, increased energy, and improved attention. These substances can elevate heart rate, blood pressure, and energy levels, and they often enhance mood. Common examples of stimulants include caffeine, nicotine, amphetamines, and certain prescription medications like those used to treat ADHD (Attention Deficit Hyperactivity Disorder). While stimulants can have therapeutic benefits, they can also lead to misuse and addiction if not used responsibly.
