Does coffee have any detrimental effect, in a spiritual/esoteric sense, aside from excess caffeine potentially disrupting your focus and keeping your heart-rate elevated? Is the use and presence of coffee in society so ubiquitous because it is another potent poison or because it helps with worker 'productivity', or is it really just a good tasting beverage and useful tool?
I know that seems like I am answering my own questions a bit, but I would like opinions from those here who meditate and also consume coffee or other products with caffeine.
