if your tolerance is as low as you say it is... then simply wearing the patch and getting a normal dose could be enough to kill you, and has killed thousands, if not tens of thousands just that way, by wearing it normally letalone smoking it or eatin git
so really think long and hard about what your going to do, i used to get irregular heartbeats on the stuff (smoked it), which scared the crap out of me, ive also over dosed (not blacked out though) just by smoking a 25 MCG patch (not the whole thing)
and generally smoking it seems to be the desired way of using it since a lot of the fentanyl gets destroyed when heat is applied and considering the amount of vapor you will lose as well, but think about what i said, how i was getting irregular heart beats just by smoking 1 hit
ill say it again, think long and hard about what your about to do, people that are not opioid tolerant die from simply wearing the patch
