Someone close to me is a recovering addict and has supposedly been taking fioricet for tension headaches. They claim it contains small traces of hyrocodone or hydromorphone but, I cannot find any information online stating either of those substances is an ingredient in this drug. I know it contains a barbiturate that can be addicting and this person's pupils have been very dialated after they claim to have taken this drug but, I suspect they are using other chemicals. Any help would be apprecitated. Thanks!
