Stimulant Pills are medicines generally used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy—uncontrollable episodes of deep sleep. They increase alertness, attention, and energy.

Stimulant Pills increase the activity of the brain chemicals dopamine and norepinephrine. Dopamine is involved in the reinforcement of rewarding behaviors. Norepinephrine affects blood vessels, blood pressure and heart rate, blood sugar, and breathing.

Most  stimulants come in tablet, capsule, or liquid form, which a person takes by mouth. Misuse of a prescription stimulant means:

• taking medicine in a way or dose other than prescribed
• taking someone else’s medicine
• taking medicine only for the effect it causes—to get high

When misusing stimulant, people can swallow the medicine in its normal form. Alternatively, they can crush tablets or open the capsules, dissolve the powder in water, and inject the liquid into a vein. Some can also snort or smoke the powder.
