“It is not. It is EXACTLY the same thing. Repeated self induced over exposure is the fault here.”
By your logic, I could start selling ice cream that contained a non-lethal dose of cyanide, with no warning on the product, just as long as it wasn’t harmful unless you ate too much ice cream (however much that is). Ludicrous.
If the level of cyanide was of a low dose that wouldn’t affect you unless you ate it twice a day for ten years, yeah, it’d be not only legal, but it is COMMON today. If you’re afraid of it, never ever eat peach ice cream. The body processes small amounts of cyanide without harm.
