HeadOn is the name of a drug derived from residue left over from Kitten Huffing that was processed into a tube. One simply applies it directly to their forehead. The instructions are repeated over and over again multiple times in the HeadOn TV commercial so that even retards and morons know how to use it, leaving only the problem of what the hell it actually does. So far the US Food and Drug Administration has not approved it, but that does not stop it from being sold in drug stores or outside of the USA. But how do you use it?!
