Drug Stimulants Research Paper
Stimulant, any of a group of drugs that excite the central nervous system, increase alertness, and alleviate fatigue. Caffeine is perhaps the most socially acceptable and commonly used stimulant. Other stimulants include cocaine and amphetamines, which create intense feelings of euphoria (well-being). Amphetamines, commonly known as pep pills or diet pills, also decrease appetite.
Stimulants work by mimicking the fight-or-flight response, in which the hormone epinephrine (also known as adrenaline), is released during stressful situations to produce an increased heart rate and increased blood flow to the muscles. Stimulants produce a similar, but often more powerful, response by increasing levels of the neurotransmitters dopamine and norepinephrine …show more content…
It is also present in most cola beverages. Caffeine was discovered in coffee in 1820. In 1838 it was established that theine, discovered in tea in 1827, is identical to caffeine. The drug increases the blood pressure, stimulates the central nervous system, promotes urine formation, and stimulates the action of the heart and lungs. Caffeine is used in treating migraine because it constricts the dilated blood vessels and thereby reduces the pain. It also increases the potency of analgesics such as aspirin, and it can somewhat relieve asthma attacks by widening the bronchial airways. Caffeine is produced commercially chiefly as a byproduct in making caffeine-free coffee (see …show more content…
Users become dependent on the drug to avoid the "down" feeling they often experience when the drug's effect wears off. This dependence can lead a user to turn to stronger stimulants such as cocaine, or to larger doses of amphetamines to maintain a "high".
People who abruptly stop using amphetamines often experience the physical signs of addiction, such as fatigue, long periods of sleep, irritability, and depression. How severe and prolonged these withdrawal symptoms are depends on the degree of abuse.
That boost we get from that morning cup of coffee is the result of the caffeine that naturally occurs in coffee. Caffeine is a common stimulant and is found not only in coffee and tea, but also in soft drinks and other foods. It can also be bought over-the-counter in tablet form. Too much caffeine can cause anxiousness, headaches, and the "jitters." Caffeine is also addictive and a person who abruptly stops drinking coffee may experience withdrawal symptoms. http://www.well.com/user/woa/fsstim.htm What Are They?
