Good when I was a teen, if you had told me my pizzas actually had LSD on them, I would have been their best customer.
Understandable but yes- irrational fear. Heat will unquestionably nullify LSD’s psychoactivity.
But I’m just curious what you are imagining? Legit fast food joint cooks your pizza, then some sly employee slips a tab or some drops on top when it’s cool enough?
It could happen. Damned unlikely though.
Being hit by a bus has got to be worse than a typical bad trip, which are just like good and bad days to me, but I have been there to say that.
Still...despite the ludicrous unlikelihood some pizza employee spiked your pizza with acid, heat will zap it off quickly, if they were dumbass enough to spike it before cooking then the LSD would be long dead.
