Personally think it's a viral trend that's tapped into the Coulrophobia of Americans and Europeans. Kinda like the "watch out for drug laced candy". Drugs are expensive, so why would a drug dealer or user lace candy with the stuff and give it out for free? Only times kids have eaten drug laced candy, is because irresponsible parents that do drugs, forgot to stash the drug candy. Now if you lived in Colorado, I would say a fear of drugged candy is a rational fear, considering the amount of kids taken to the hospital due to ingesting edibles.
