He's obviously talking about alcohol (it takes seconds to consume an amount of alcohol that can result in death, yours or someone else's from a fight or car crash) and firearms (should be obvious).
Sounds like you're implying some sort of mischaracterization of sugar here which minimizes the former in a weird way.
I wanted to draw the distinction between something that destroys lives over a longer period of time (smoking) VS something like gambling where you could lose your life's savings in seconds.
The alcohol mentioned in a sibling comment also ticks the box.
For the sugar, I'd say yes, no, no, yes and "not too much, but I'm keeping an eye out".
