I find that difficult to believe. If my skin can extract the drug I'm sure some enterprising bright fool will find a way to replicate that process in a laboratory. Wonder what happens if some druggie uses the patch in random orifices?
Believe it or not, it makes no difference to me. The proof will come in time as this products is commercialized and put into use. BTW, it makes no difference what “orfice” the druggie may try to stuff the patch into. That’s laughable.
