I mean, I understand people value their drugs, but people place a pretty high value on their trolling capabilities as well. Don't forget people have hidden razor blades (which aren't cheap) in homemade candy apples (which is work) for apparently the sole purpose of the *knowledge* that some kid in their vicinity will slice their mouths open. People have also fed edibles to their dogs. Maybe I'm just a pessimist, but I could see someone doing this-- either intentionally or as a mistake

I can, however, see someone stoned to the bone giving away edibles by mistake. Regardless of intent I'm sure its happened in one form or another

Didn't the drug in candy urban legend come from some parent hiding their drugs in their kids candy?

Well the good news is that it won't hurt the kids like other things occasionally found in Halloween candy.
