>>11943165There are certain alleles of a caffeine metabolizer enzyme that are associated with higher rates of cardiac issues as well as other alleles of it associated with lower rates. Coffee can be good for you depending on your genetic makeup, however, if you feel that coffee is making you a nervous wreck or giving you issues, then it probably isn't good for you. That's not to mention all the other factors that come into play when dealing with psychoactive drugs. We can't know exactly how caffeine works in the same way that we hardly understand all of the benzos and shit that psychiatrists prescribe. The best way to understand drugs like this is to look at their effects empirically, over long periods of time, ideally in other people and in yourself if you deem the effects in other people to be "safe." And, no, I don't feel like digging up the paper I was referring to.
