Marijuana?!? I never heard that! Where/when I was growing up, it was always hard, powdered drugs. Like cocaine in a pixie stick. Oh and razorblades in candy apples. I don't know about the razor blades, but if I remember right, there's only been one proven instance EVER of people intentionally trying to harm kids through Halloween candy, and it was the father? Or step father? So I wouldn't even really count that.
