(10,789 posts)as we are all more or less addicted to sugars and so forth by nature. Some sugars (and chocolate) have the same kind of effect on brain chemistry as scheduled drugs.
It does come down to harm though. Refined sugars might mess with your metabolism a bit, causing weight gain and complications, but on the other end of the scale are things like heroin and meth. These addictive substances that will kill you relatively quickly, and so are not regulated but banned. Even more, they seem to hijack the parts of the brain that might chose to stop taking them. Nicotine is similar but milder, and so is regulated rather than banned, which I think is fine. Marijuana should be treated the same. And to be fair heart disease is much less certain, perhaps involving genetic inclinations and other behavioral factors besides.
I only know about caffeine from personal experience, where I drank coffee daily years ago, but became less and less tolerant of it as I aged. Headaches, stomach aches and a bit of dizziness, so I no longer partake. There were no withdrawals, though the smell of good coffee still attracts.
