Energy drinks consumed to increase stamina do more harm to health than good and can lead to addiction to alcohol, a study released by NGO Centre for Science and Environment said. The CSE had tested two samples each of eight popular energy brands sold in India and found 44 % of the samples breached the safety limit of 145 particles per million (ppm) of caffeine prescribed under the Prevention of Food Adulteration Act, 1954.
Caffeine is a psycho-stimulant and can lead to seizure, strokes and even death.
