What are your thoughts on people who self-medicate with caffeine due to their baseline ability to focus being reduced (which in modern society is cause for trouble)? That’s the reason for starting caffeine use for many. My use is also light and fully legal, but personally I’m not sure that this is something that’s so binary. It seems more likely to sit on a spectrum, as most things do, and is largely dependent on the individual due to wide differences in brain and body function. It’s the same reason why the prescription drug that works wonders for one person and do nothing or worse, be detrimental for somebody else. We’re not all identical units of a particular model rolling off an assembly line somewhere, after all. So I guess I would say that yes, we should be more conscientious of how substances (even those that are common) interact with our minds, but I have a hard time labeling them all as harmful. It’s just too broad of a brush.
