„A No. Coffee drinkers do not require increasing amounts of caffeine over prolonged periods of time (characteristics of addictive substances), and they can moderate or change their consumption with no difficulty. Moreover, coffee consumption does not cause psychosocial effects.“

Coffee/Caffeine and Degenerative Brain Disease (Parkinson's & Alzheimer's Disease)
„The available evidence consistently demonstrates that coffee drinkers have a lower risk of developing Parkinson's disease (1) and is inversely and significantly associated with risk of Alzheimer's disease (2 & 3). However, a study which identified 154 cases of Parkinson's disease, found that while coffee or caffeine consumption lowered disease risk in women who did not use postmenopausal hormones, they raised disease risk in women who used postmenopausal hormones (4). More studies are needed to decide whether the combined use of oestrogen and coffee or caffeine increases Parkinson's risk.“

„Caffeine is addictive, it's true-- research shows that, although humans seem not to develop tolerance to caffeine (ie do not need more and more, over time, to get the same results, unlike, say, heroin) it does appear that caffeine does cause dependence in humans. This means that the body becomes used to receiving a certain amount of caffeine at regular intervals and temporary effects, such as headache or fatigue, will be apparent each time caffeine is not received when the body expects it. These symptoms are, however, short-lived and usually disappear in several days. Slowly tapering off consumption of caffeine will minimise these effects.“

Caffeine and your body. - coffeecrew.com - victoria, b.c. canada
„Caffeine is an addictive drug, affecting 90% of all Americans, which alters the brain's natural state, and stimulates it in a manner similar to the amphetamines cocaine and heroin. The mechanisms employed by caffeine, cocaine, and heroin, are to close blood vessels in the brain, so the brain and body cannot sleep, to cause the release of adrenaline into the body, so the body remains active and alert, and to manipulate dopamine production in the brain, so the person experiences a temporary "high." Caffeine may be found in its natural state in many plants, including tea leaves, coffee beans, and cocoa nuts. The pure form of caffeine is a bitter, white, crystalline powder derived from the decaffeinating process of coffee and tea. The vast number of products in which caffeine comes, range from coffee, to tea, to colas, to milk chocolate, and to pain relievers, just to mention a few.“

Effects of Coffee and Tea on Bone Health
„The link between caffeine intake and bone loss is not clear, as many studies have shown. Researchers have found a higher rate of spinal bone loss among coffee drinkers (3 or more cups per day), but bone loss in the hips and legs seem uneffected by caffeine consumption.“

„Coffee drinking in moderation, 4-5 cups per day, is perfectly safe for the general population and may confer health benefits. However, it has been suggested that caffeine, the naturally occurring mild central nervous system stimulant found in tea, coffee, and cocoa is an addictive substance. This is simply not the case.“
