No. Energy drinks are neither addictive nor do they contain any addictive substances. The ingredients of energy drinks are found in other foodstuffs and some ingredients occur naturally in the human body. This is also true for taurine, which is present in seafood and found in the human body. There is a consensus that caffeine, which is also a natural ingredient in foodstuffs such as coffee, tea or chocolate, is not addictive. Energy drinks contain about the same amount of caffeine as a cup of coffee.
