Maybe it’s Brazilian exploding tobacco?
im sorry i cant help it its genetic please dont hurt me mister
But seriously, Astroboy, what kind of cigarettes are they? Is it always the same brand that pops? Consider the possibility that it’s something to do with the manufacturing process for that brand. Maybe Phillip Morris does something different to its tobacco for cigarettes that instead of making it into little leaves, makes it into leaves and crumbs which occasionally pop.
Maybe tobacco just does that, and you never happened to notice it before. If you look into a campfire, the logs don’t burn evenly like a gas flame. They hiss and pop as different components of the wood start to burn.
And my suggestion about the fireworks factory wasn’t entirely facetious, I don’t think. Factories do change hands and get used for assembling different things. It’s not outside the realm of possibility that your cigarette factory was formerly used for packaging dry dog food or tooth powder or something, and there are still particles of “whatever” that get into the cigarette-rolling machine. Maybe you can sue somebody…
And I’d like to thank Atropos for the “exploding bug head” suggestion. My son’s smoking friend is going to hear ALL about it. “Forget about lung cancer, didja ever wonder what ELSE might be in there along with the tobacco…?”
okay im done now…
