(FOX NEWS) — If you’re a coffee lover you might be able to say you have caffeine running through your veins.
According to a study published in the Journal of Pharmaceutical and Biomedical Analysis, drinking coffee, or tea, or even eating a bit of dark chocolate could leave traces of caffeine in your system.
Scientists testing 18 batches of human blood serum say each one tested positive for caffeine.
But the researchers say these traces are nothing to be worried about and are not considered a “contamination.”
