Did he choke on it?
No
Is the fact that he did something with the snack besides eat it the root cause of the risk to his life?
Is it a weird sex thing?
Is it related to an allergy?
No
Did the potential poisoning involve a substance that was (or would have been) ingested? Or inhaled?
Yes
I have to wonder how coy I should be on some of these answers…
That was two separate questions (note the two question marks). Which one was the “yes” in answer to?
Was ingested, no
Was inhaled, yes!
Is a chemical reaction involved? (Other than the ones that normally result from eating, breathing, etc.)
Did he add something to the snack?
No
No
Did he crush and snort something that really should only be taken orally?
Did he cook a snack intended to be uncooked?
Did he smell the snack before eating it, to appreciate the aroma, and then accidentally inhale part or all of it, causing him to choke?
Specifically, was he snorting Pez?
No
No
Almost… but no
No
Guys, I want to apologize for something.
Earlier I said that the knowing what the snack was wouldn’t be helpful, but on thinking about it, I realize that it’s the exact opposite. What the snack is, is a crucial part of the story and what lead to the problems he experienced.
I’m sorry, apparently I am not very good at this side of the game. 
Animal, vegetable, or mineral?
Vegetable
Did he react the way any person would have reacted, or was his reaction sui generis?
