Sugar is the most destructive drug on earth and it's not close.

Not convinced.
I've probably had around 50 Metric tons of white, processed sugar in my teas and coffees alone since I was 4. Add to that all the sugar from candy, cakes, and soda? You'd have to measure it in planetary mass percentages.
I'm pretty sure that taking one or two pounds of coke over that same timeframe would literally end me.
