Tea always has caffeine, but not as much as coffee. So, yes to your question.
Some are naturally caffeine free, some contain 100% the caffeine of a cup of coffee. It depends on the type.
The "boost" from coffee comes from the caffeine. The answer would be Yes. Regular coffee gives your metabolism a bigger boost than decaffeinated coffee. The average mg's of caffeine in an 8 ounce cup of regular coffee is about 100mg. Decaf coffee is not caffeine free and contains from 15 to 20 mg of caffeine in an 8 ounce cup
Coffee beans are naturally caffeinated so the existed caffeine must be removed, i.e. de-caffeinated. Cola (Coke, etc) often has caffeine added as a separate ingredient, so if that ingredient is skipped, the cola is free of caffeine.
It depends on the tea. Herbal teas generally are caffeine-free. Green tea is caffeine-free. Black teas (Pekoe, Earl Grey, etc.) *do* contain caffeine.
Instant coffee has about 65-100mg of caffeine per 12 oz.
No, you can get your coffee with plenty of caffeine in it. Caffeine occurs naturally in coffee and it is only through processing the caffeine out of the beans do you get decaf coffee.
Look for the word "Decaffeinated" or "Decaf" in the packaging. Do note that even though most of the caffeine in decaf have been removed, not every decaf brand will be 100% caffeine-free.
Yes you can buy decaffeinated tea and coffee from any super stores
If a person is highly susceptible to caffeine addiction it may as it's impossible to make %100 caffeine free coffee
