How To Drink Cocaine In Canada

According to the CAC’s newly released 2013 Canadian Coffee Drinking Study, coffee is a dominant beverage in the Canadian market. Only tap water enjoys equally high past-day penetration. The results of the research show that approximately two-thirds of adult Canadians (65%) consumed coffee in the past day. Approximately three-quarters of Canadians aged 18-79 (78%) indicate they’ve consumed coffee in the past week. (Coffee, 2013) Also, through the survey, coffee is the second most traded commodity in the world after oil. The children aged under 18 is usually supervised by their parents. They are not allowed to drink coffee every day. Thus, this report is written for the adults who drink coffee as their daily routine and help them understand how

does coffee actually work in their body.

Almost all the coffee drinkers know that coffee has the stimulating effect, but how does it work and what actually happens in our brain?

At the every moment when we are awake, there is a chemical compound called adenosine is slowly accumulating in our brain.

Our nervous system is actively adjusted to adenosine levels through receptors. The adenosine binds those reactors, which slow down our brain activity. The more adenosine there is the more tired our brain feels. When adenosine levels reach a certain point in your brain and spinal cord, your body will start nudging you toward sleep, or at least taking it easy. (Purdy, 2010) Which make sense, the longer we awake, the more fatigue we become. Conversely, the concentration of adenosine decreases while we sleep; it helps blood vessels to dilate, most likely to let more oxygen into the brain during sleep. Then the wakefulness is gradually promoting during sleep. Caffeine, a bitter substance, which is found in coffee, plays the significant role in stimulating our central nervous system. It has effects on the body's metabolism, which can make us more alert and give us boost energy. However, it turns out that caffeine in our coffee is incredibly similar with adenosine in chemical structure (appendix1). From the appendix1, we can see that they are both organic chemical molecules with nitrogen rings (The nitrogen elements in the rings is marked in blue). The caffeine molecule works its way through our bloodstream and into our brain where it begins to compete and combine with the adenosine reactors. Plenty of caffeine molecules bind the receptors in our brain, which

takes up the receptors of adenosine. However, they are not adenosine after all, caffeine doesn't slow down the cell's activity like adenosine would. Thus, we cannot feel the sleepiness effect. As a result, adenosines can no longer bind its reactor meaning our claiming properties are diminished. However, under the effect of adenosine, the nerve cell speed up, which is definitely benefiting for us when we are feeling tired. Meanwhile, another problem is coming with its stimulation. With the long-term use of coffee, our brain response by creating more and more receptors to combine the increasing number of caffeine. Compared to the initial stage of drinking coffee, more caffeine is needed to elicit the same response. Thus, when we try to quit drinking coffee or miss our daily intake, we might experience some withdraw symptoms including headache, insomnia, and Anxiety. Also, we will feel more tired than we would have before we ever drink coffee. Therefore, there is a high probability to be addicted to caffeine. From this point of view, caffeine actually shares a number of traits with more notorious drugs such as amphetamines, cocaine and heroin, just lesser degree.

Except that, caffeine's effect on the brain causes increased neuron firing. The pituitary gland senses this activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline (epinephrine), which is known as ‘fight or flight’ hormone. With the production of adrenaline the heart rate increase. It also gets our heart pumped or even opened the airway. This explains why, after drinking cups of coffee, our heartbeats grow faster, our body feel cold, and we feel panic and excited.

Furthermore, coffee influences our mood by affecting the dopamine levels in our body.

Dopamine elevates our moods to make us feel better and stave off depression, which is why there is so much coffee consumption in areas that lack the sunshine for extended periods, such as the USA Pacific Northwest and Scandinavia. Dopamine also helps create motivation and contributes toward conscious body motion. Some research even points to coffee drinkers having fewer problems with depression and Alzheimer's disease than non-coffee drinkers. (Louis, 2012). Here, caffeine, as a competitive antagonist at adenosine receptors, may produce its behavioral effects by removing the negative modulatory effects of adenosine from dopamine receptors, thus stimulating dopaminergic activity. Thus, we feel happy because of preventing adenosine

reabsorption.

To sum it up, caffeine, as a kind of stimulant, it stimulates our nerve system in our brain and causes the pituitary gland creates and transmits the signals to the different glands in our body where starts synthesise hormones. Those hormones are the actual substances, which manage our feeling.

Even though there are lots of benefits of drinking coffee, it doesn’t mean that we can drink coffee as much as we expected. According to the research of FDA (food and drug administration), 400 mg per day of caffeine (85mg caffeine per cup of coffee) is a safe dose of caffeine for healthy adults. However, the statics is just a conclusion based the most adults. Some people are really sensitive to caffeine; half cup of coffee is strong enough for them to experience all the side effects of caffeine while some feel still nothing after consuming 10 cups of coffees. People have to take their own health condition into consideration when they drink coffee.
