Drug addicts seem to do it to themselves on accident all the fucking time. If a street junkie can do it, then I'm sure some training (that does not amount to a medical degree) would be enough.
The medical degree isn't about knowing how to knock them out. It's about knowing how to bring them back.
And if you use the "self-clean" feature on your oven (you shouldn't regardless), it's going to spew out some nasty shit.
