Obviously, I'm hooked on coffee and in one sense this makes me a drug addict. I'm not alone, however. The consumption by North Americans alone is estimated at billions of cups annually. You may think it nonsense to suggest anyone who needs a daily injection of caffeine is an addict. You'll change your mind about this if you try to give up your daily cup of coffee.
Coffee is definitely addictive but, on the other hand, it's a pleasant, stimulating drink.
One or two cups of coffee a day may do you more good than harm. I've seen reports that a mild coffee habit greases the workplace and makes people more productive and, in some cases, more creative. While the reports came from food companies that control the coffee bean market, there's some truth in them. The report didn't associate blood pressure and cholesterol with caffeine, but both are affected adversely by high coffee consumption. There may be other problems as well for people who drink coffee excessively.
