What is caffeine?

chemically, pure caffeine is a plant -based alkaloid that stimulates the central nervous system of any creation that uses it. In nature, it serves as a form of pest control for certain plants such as cocoa trees, coffee shrubs, Yerba Mate and tea room. Caffeine causes insects and other pests to collapse from the effects of excessive stimulation. However, it was not described as a controlled substance, so its use in tea, coffee and soda is not illegal. Coffee beans contain considerable quantities, while tea leaves and Yerba plants contain less. Cocoa beans also contain caffeine, but contain much higher levels of another alkaloid called Theobromine. This powder form is in fact a scientific definition of Bitter, and therefore many caffeine -containing drinks also contain a large amount of sugar or other sweeteners. This contained in stimulating pills, such as no-DOZ, is not diluted with sugar, so the pills can be really bitter.

caffeine may not be addictive in a classic sense, but the body builds tolerance over time. Some people consider it difficult to function without at least one cup of strong coffee or tea in the morning. The stimulating effects are caused by central nervous reactions. The heart rate increases, the blood vessels are limited and the air passages are released. This effect may take up to an hour.

There is something like downloading caffeine. Regular consumers of coffee or soda can have painful headaches if the body is denied caffeine. Without stimulation provided by this alkaloid, blood vessels open and increase blood flow. The tradition for download is more caffeine. This is also why many headache medicines contain small amounts.

It would be very difficult to consume enough caffeine for deadly overdose, although some deaths were reported. However, one would have to drink several hundred cups of coffee or ingestion at least 75 tablets to reachtoxic levels. The use of several stimulants of vivarin or no-DOZ to increase mental awareness should not be harmful in the long run, but sudden accidents may occur as the effects of the drug wear. If you do not want to experience the dark side of the drug, so keep your study sessions all night or long distances.
