Michael Laufer doesn’t have a life-threatening allergy to peanuts or bees. So he doesn’t need to carry an EpiPen, the automatic drug-injecting device that people with severe allergies stick into their thighs after accidental exposures.

I get the spirit, but... uh... there's a subtle difference between DIY vaping fluid and DIY life-saving steroids. I mean, if I needed an epi-pen I might roll that way. But if my daughter needed an epi-pen I'm whippin' out the credit card. Crushing liability is occasionally an asset.
