i looked in my books and i couldnt find anything unfortunitly i let a friend borrow my RX index book but i did find it in another but listed as p-Hydroxyphenolacetamide which is another name for it...but it says that it is a component for many cold and cough otc meds...its also a component of vicodin so that might be the codine make-up...but hey man take it whats the worst that can happen?...but ill see if i can find more info once i get my books back
