Examples of common stimulants include Caffeine , Amphetamine s, Ecstasy and Cocaine , although there are many others. AMPHETAMINES See Also: Amphetamine Amphetamines are synthetic stimulants. They were first discovered in the 1800s, but their medical uses were not recognized until the 1930s. Then they were used to counter low blood pressure, help asthmatics breathe more easily and decrease appetite. However, taking a lot, especially over a few days, can produce panic and paranoia. Injecting amphetamine is particularly dangerous. If injecting equipment is shared, there is the risk of infection including Hepatitis and HIV . Attention Deficit Disorder is often treated using stimulant medications pharmacologically similar to amphetamines. The most popular drugs include Ritalin (methylphenidate), Adderall (amphetamine), and Dexedrine (dextroamphetamine). COCAINE See Also: Cocaine Cocaine is made from the leaves of the Coca shrub, which grows in the mountain regions of South American countries such as Bolivia , Colombia , and Peru . In Britain and America, the most common form of cocaine is a white crystalline powder. Most users Insufflate it intranasally, often using a rolled banknote or straw. Cocaine is sometimes made into a solution and injected by users. Crack Cocaine is a smokeable form of cocaine. It is usually smoked in a pipe, glass tube, plastic bottle, or foil. Cocaine and crack are powerful, but short-acting stimulant drugs. Crack in particular has strong but short-lived effects. Both drugs tend to make users feel more alert and energetic. Many users say that they feel very confident and physically strong. Common effects include dry mouth, sweating, loss of appetite, and increased heart and pulse rates. Excessive doses can cause death from respiratory failure or heart failure. CAFFEINE See Also: Caffeine Caffeine is a drug that is found in Tea , Coffee , Cocoa (contained in Chocolate ), and many Soft Drinks . There is no law prohibiting the sale of any of these products. Caffeine stimulates the body, increasing Heart Rate and Blood Pressure , and alertness, making some people feel better able to concentrate. Caffeine is a Diuretic . There have been concerns about the amount of caffeine consumed by young children particularly in soft drinks and chocolate. Some people have suggested that children that consume a lot of caffeine may become hyperactive. MDMA See Also: MDMA MDMA is an illegally-manufactured drug that comes either in tablet or capsule form (known as Ecstasy ), as a powder (MDMA dibs or powder) or crystal (MDMA crystal in the US, Crystal in the EU). The consumption of a typical dose increases the blood pressure and heart rate, and loss of appetite is common. Users of MDMA experience brief nausea, rapid sweating, and a dry mouth and throat. The appearance of ecstasy tablets varies considerably, ranging from brown, white or pink tablets to yellow, clear, red-and-black or red-and-yellow capsules. Some also have pictures, designs or logos. It is very unusual for an ecstasy pill to contain only MDMA; they frequently contain amounts of other drugs which may include any of a wide range of substances such as MDA , MDEA , MDBD , PCP , DXM , PMA , Ketamine , Caffeine , Amphetamine , Methamphetamine , Ephedrine , Pseudoephedrine , Aspirin , Paracetamol , Fentanyl and, in a small number of cases, Heroin , Cocaine , Mescaline , DOB , or LSD . In some cases the substance sold as ecstasy pills need not contain MDMA at all. Contrary to popular belief amongst non-users, MDMA does not cause hallucinations, however many of the other drugs which are included in Ecstasy pills are hallucinogens. Deaths that have occurred as a result of consumption of ecstasy have mainly been connected with non-stop dancing in hot, crowded clubs leading to overheating and dehydration, to multiple-drug overdoses, or Hyponatraemia (" Water Intoxication "), as in the case of Leah Betts . Safety advice when using MDMA includes taking a break from dancing to cool down, drinking moderate amounts of water (sufficient to replace that lost by sweating; the commonly given advice here is ''sip don't gulp'') along with small amounts of salty foods or drinking Sports Drinks instead of water (to restore Electrolytes , thereby preventing hyponatremia) and avoiding Diuretics (caffeine, alcohol). ANTIDEPRESSANTS See Also: Antidepressant Antidepressants are not considered stimulants, as they do not act directly on the sympathetic nervous system and generally do not produce an immediate effect on mood. A possible exception is Bupropion , whose chemical and Pharmacological properties are similar to those of stimulants. OTHER Recently, there have been improvements in the area of stimulant pharmacology, producing a class of chemicals known as '' and Adrafinil , marketed as Provigil and Olmifon, respectively. In Russia, Carphedon is sold as a general stimulant under the brand name Phenotropil. SEE ALSO EXTERNAL LINKS
