recently i acquired some fentanyl patches for the first time.. they are 75um/g or something like that. I put 1 on 24 hours ago and ive been feeling pretty good and a pretty steady relaxing but not strong high for the last 15 hours or so.. i was wondering if these are supposed to last 72 hours if it was possible to remove the patch and take whats left of the gel and smoke it or eat it. will it get me really high and how long will its affects last? also how do u go about smoking it or eating.. i did a search but could find nothing. thanks for your time ~ klast
