Caffeine's effects are addictive.
What is addictive? Addictive refers to a strong dependence on a drug characterised by severe withdrawal symptoms, tolerance to a given dose and the loss of control or the need to consume more and more of the substance at any cost. Addicts tend to exhibit anti-social behaviour or even commit crimes to perpetuate the abuse.

The Diagnostic and Statistical Manual for Mental Disorders (1994), does not list caffeine as a substance that causes addiction. Consumers of caffeine-containing beverages do not fall into this category.

Caffeine is a risk factor for osteoporosis.
Osteoporosis occurs when there’s insufficient dietary calcium and vitamin D, high protein diets, smoking, the onset of menopause, low oestrogen levels, low body weight and a lack of physical activity.

It has been proved by several studied that consume moderate caffeine doesn’t increase the risk of developing osteoporosis. National Institute of Health Consensus Statement on optimal bone health does not list caffeine amongst the risk factors which modify calcium balance and influence bone mass. A study by Penn State Medical School found that lifetime consumption of caffeine had no effect on bone density in 188 post-menopausal women.

Caffeine does cause a small amount of calcium to be lost in the urine about the amount in one to two tablespoons of milk per cup of tea or coffee. For this reason, nutritionists recommend that women take their coffee with added milk, drink one extra glass of milk daily or take a calcium supplement if they are heavy coffee drinkers (over 5 cups of coffee daily).

Pregnant women should avoid caffeine.
Most physicians and researchers agree that moderate amounts of coffee daily will have no adverse effects on the outcome of the pregnancy or the infant's health. Many women find they experience taste changes during pregnancy and cannot drink tea or coffee. So, for all pregnant women, you can still enjoy the taste of coffee, as you like in moderation.

Caffeine causes cancer.
Two studies of large numbers of people in Norway and Hawaii found no relationship between regular coffee consumption and cancer risk. Two projects conducted on caffeine - one in Japan and the other in Germany - demonstrated no link between caffeine consumption and the incidence of tumours in test animals.

Caffeine increases the risk of heart disease.
Scientists now agree that regular caffeine use has little or no effect on blood pressure, cholesterol levels or risk of heart disease. Studies show that while first-time caffeine use can cause a slight increase in blood pressure the changes are minimal and disappear with regular use.
It has also been found that only boiled, unfiltered coffee, such as that taken in some Scandinavian countries, elevates cholesterol. It seems the oils in the coffee that are not filtered out are responsible for this effect, not the coffee or caffeine

Caffeine adversely affects the health of children.
Children generally consume much less caffeine than adults do, since soft drinks and tea are their primary sources of caffeine. Children generally have the same ability to process caffeine as adults. Studies have shown that foods and drinks containing caffeine, when taken in moderate amounts, have no detectable effects on activity levels or attention spans in children.

Caffeine has no health benefits.
Caffeine which contained in some beverages (tea and coffee), have been found to contain antioxidants. Antioxidants terms of heart health and cancer prevention. Caffeine is well recognised as increasing both alertness levels and attention spans. A cup of coffee or tea is often recommended to counter sleepiness. Caffeine may be useful in treating allergic reactions due to its ability to reduce the concentration of histamines, the typical body response to an allergy-causing substance. More research is needed in this area before conclusions can be drawn. Caffeine has long been known to help many people suffering from asthma.
