While clinical responses of Caffeine are widely understood the cellular basis is not well known. (Coffee House)"Currently, it is believed that xanthines act as adenosine-receptor antagonists. Adenosine acts as an autocoid, and virtually every cell contains adenosine receptors within the plasma membrane. Adenosine exerts complex actions. It inhibits the release of neurotransmitters from presynaptic sites but works in concert with norepinephrine or angiotensin to augment their actions. Antagonism of adenosine receptors by caffeine would appear to promote neurotransmitter release."(Coffee House) In other words, the molecular structure of the caffeine molecule is similar to that of adenosine. *
This similarity results in the caffeine molecule binding to the nerve cell membrane. Therefore, the signal to stop producing adenosine that would have been sent by the adenosine becomes blocked, which results in a surplus of adenosine and explains the stimulatory effects of caffeine.
Decades of research and centuries of human consumption suggest the relative safety of caffeine. According to the National Library of Medicine, more than 19, 000 scientific studies to date have been conducted on caffeine, and the US Food and Drug Administration still considers caffeine to be "Generally Recognized as Safe." A study at the University of California showed that the average daily

Based on my data, I think my isolation was somewhat of a success and in some ways not. I was able to obtain a pure recovery from the crude caffeine of 21.46%. It is not significant amount, but it seemed to be enough. A reason for some loss in my data was that some of the crystals were lost in the process of removing the inner tube. In addition, although I was unable to perform the NMR, I perform the IR, but my spectra resemble more like a blank. I obtain 0.05 grams of pure crystal caffeine but it could be that during my removable of the inner tube that when both of the tube accidently bumped that I lost some of the crystals, which resulted in not enough caffeine for me to get an IR spectra with all the peaks.
Due to the fact that caffeine is a drug that is so heavily used and relied on in our society, the criminalization of it would have immense ramifications. The outlawing of this substance would result in the loss of many items of food and drink that are used daily in Canadian society.

Caffeine Effects In The Brain Caffeine acts in a multitude of ways in the brain. The most recent studies explore the cooperative effects of adenosine and dopamine, as well as the increase in calcium in the interstitial fluid and possible accumulation of cyclic adenosine monophospate. The most popular discussions of earlier studies of caffeine demonstrate its antagonistic effects on adenosine receptors. While it has been reported that adenosine receptors are located throughout the brain, the various subtypes can be found in very specific areas.
Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks.

It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is
