The study find that coffee drinkers  sniff out even tiny amounts of coffee and are faster at recognising the aroma; compare to non-coffee drinkers, new research has find. Coffee is a brewed beverage prepare from roasted seeds; commonly call coffee beans; of the coffee plant. Due to its caffeine content; coffee can have a stimulating effect in humans. Today, coffee is one of the most popular beverages worldwide.

Stimulating effect in humans

It is suppose that the Ethiopians, the ancestors of today’s Galla tribe; are the first to have discover and recognize the energizing effect of the coffee bean plant. However; no direct evidence has ever been find revealing exactly where in Africa coffee grew or who among the natives might have used it as a stimulant or even known about it there earlier than the seventeenth century.

The earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the fifteenth century; in the Sufi monasteries of the Yemen in southern Arabia. Habitual coffee drinkers are not just more sensitive to the odour of coffee and faster to identify it; but the more they craved coffee; the better their ability to smell it became.

Using aversion therapy

It is the first time evidence is find to prove coffee ; addicts are more sensitive to the smell of coffee. The results could open the door to potential new ways of using aversion therapy to treat people addicted to substances with a distinct smell; such as tobacco and cannabis. The research was led by Dr. Lorenzo Stafford; an olfactory expert in the Department of Psychology at the University of Portsmouth.He said:

They  found the higher the caffeine use, the quicker a person recognised the odour of coffee. “We also found that those higher caffeine users were able to detect the odour of a heavily diluted coffee chemical at much lower concentrations, and this ability increased with their level of craving. So, the more they desired caffeine, the better their sense of smell for coffee. “

Trigger craving in users

They have known for sometime that drug cues (for example, the smell of alcohol) can trigger craving in users; but here we show with a mildly addictive drug, that craving might be linked to an increased ability to detect that substance. “Caffeine is the most widely consumed psychoactive drug and these findings suggest that changes in the ability to detect smells could be a useful index of drug dependency.
” The team wanted to examine if there were any differences in the ability of people to smell and respond to the odour of coffee; depending on whether or not they were big coffee drinkers. The results point firmly to a link; with heavy coffee drinkers being more sensitive to the smell of coffee, and the smell being linked to their cravings.
