ENERGY DRINKS, CAFFEINE & SUPPLEMENTS Created by Naval Hospital Health Promotion 2008
How are stimulants used? Medically, they are now prescribed for only a few health conditions, including narcolepsy, attention-deficit hyperactivity disorder and short-term treatment of obesity. They are swallowed and may be injected when abused.
Short-term effects of stimulants Stimulants increase the amount of norepinephrine and dopamine in the brain Increases blood pressure Increases heart rate Constricts blood vessels, Increases blood glucose, Increases breathing rate. Effects can feel like an increase alertness, attention, and energy along with a sense of euphoria. There is also the potential for cardiovascular failure (heart attack) or lethal seizures.
Long–term effects of stimulants Stimulants can be addictive in that individuals begin to use them compulsively. Taking high doses of some stimulants repeatedly over a short time can lead to feelings of hostility or paranoia. Additionally, taking high doses of a stimulant may result in dangerously high body temperatures and an irregular heartbeat. There is also the potential for cardiovascular failure (heart attack) or lethal seizures.
