Praise be to Allaah.
After studying a
number of medical reports and articles, and the results of research, we
cannot be certain whether these drinks are harmful or not, or about what
quantity is harmful, or for which sector of people. These drinks still need
further study in order to determine their real effect on people.
But in the light
of what we have read about them, most authors warn against them and doubt
whether they are healthy. Many doctors have advised that it is important to
do without these drinks and to do other healthy things instead such as
exercise, healthy meals, getting enough sleep, and so on.
The warning is
more serious for those who have heart problems, high blood pressure or are
young (under 16 years).
We should take
into account the fact that there are hundreds of type of these drinks, which
vary in content, and this makes it more complicated to research them,
because what may apply to one drink may not apply to another, and so on.
Until there is
more research which shows the real nature of these drinks, we cannot issue a
ruling as to whether they are halaal or haraam.
If you want to be
on the safe side with regard to your health, and heed the warnings of many
doctors, that is better.
