Hi all! I have read that many people will cut a piece or two of the Fentanyl patch and place it in their mouth for a period of time. Some people say to chew it, but I think they really mean to place it in one's mouth as I am sure the bio-availability of the patch is much more effective sublinguilly where as chewing it will waste a lot of the drug and its pleasureable effects. Does anyone have idea how long a piece of a Fent. patch can last by taking it in the aforementioned method of placing it between one's cheek and gums? Will the actual drug itself be all released sublingually in about an hours time? Can one keep it there for about an hour or two and then return to the same piece a few hours later and still get some of the drug? Thanks for your responses ahead of time!
