What it actually means
Stimulants act on the brain's dopamine system — then the system adapts.
Stimulant use disorder is a chronic condition involving the compulsive use of stimulant drugs despite negative consequences. The category includes illicit stimulants — cocaine and methamphetamine — and the misuse of prescription stimulants, whether prescribed to the woman herself or obtained from someone else.
Stimulants act on the brain's dopamine system, producing a surge of energy, focus, and reward. Over time, the brain adapts. The same dose stops producing the same effect, and the natural baseline — without the substance — feels flat, foggy, or unbearable. That shift is biological, not a matter of character.
