Parents are concerned, yet the threat is virtually non-existent. Each year, local police departments issue warnings to parents about potentially tainted Halloween candy. Apparently, the threat is no longer razor blades and needles slipped into candy, but THC-laced candy since recreational marijuana is legalized in 11 states (and Washington, D.C.). Although a child eating marijuana edibles would not be a good thing, parents need not worry: No one is going to give your kid any on Halloween.
Think about it from the perspective of the person handing out the candy. What is the upside to it? Yes, there are bad people in the world, but handing out marijuana candy would not only be against the law (recreational marijuana is not legal for minors) but incredibly expensive.
