Which drug is commonly found in coffee and tea?

Caffeine, found naturally in coffee beans and tea leaves, is the world's most widely consumed stimulant. It boosts alertness by blocking the neurotransmitter adenosine, which normally promotes sleep and relaxation. Interestingly, caffeine can also temporarily improve memory and concentration, making it a favorite for those needing an energy boost.

No in tea it is tein. And if you have milk in tea it gets overstocked in your body.

Add chocolate, and some ginseng has caffeine added to it.

Boiled tea leaves to purify caffeine. When I picked up the beaker, the bottom stuck to the burner and had to clean up he syrupy mess and start over. I didn't like boiling acid to begin with, but got close to the amount of caffeine on the label.
