A fentanyl patch contains 100-fold more fentanyl in the reservoir than what is posted on the patch. For instance, 100mcg/hr patch will have over 10mg - thats milligrams - of fentanyl. This provides a rather large source for potential abuse. Overdose and deaths have occurred by patients in the following ways:
Ingesting
Placing in a cigarette and inhaling
Inadvertent overdose by sleeping with an electric heating blanket and increasing absorption through the skin
Steeping the patch in hot water
Actually stealing the patches off of dead bodies in the morgue
