If it's synthetic it could be, but the natural one present in coffee and other stuff ain't a problem, you need really high dosage to get something like that.
And you have extensive material about the benefits it carry, there's not a single health benefit on alcohol or nicotine, putting the 3 together is, in my view, non sense.
There are studies in caffeine and sleep disorder, anxiety disorder, addiction and cardiovascular issues around. So it’s quite subjective!
Ok and there are plenty of them telling that it delays dementia and Alzheimer's, prevents cancer, and much more. If it's a normal intake you won't have a problem, putting it alongside alcohol and nicotine is my issue.
It can be both! Depends on your individual needs / circumstances!
And mostly how much you take for then to be a problem, if it's your normal coffee consumption you'll get the benefits and none of the damages.
There might be people with any healthy caffeine threshold! Is quite individual!
