I am new to the whole patch world and came across some 50 mcg patches over 72 hours. these are not the gel kind and are made by Apotex corp. I have been doing many dilaudids and have been a heroin user in the past. I am out of the dilaudids and only have the patches left and 4 at that. Am trying to make a Dr. appointment to get subutex so hopefully my withdraw won't be so bad and maybe one day I can quit. Will the fentanyl patches show up as an opiate on a normal drug test or not is my main question and also what is the best way to use the patches for recreation and to not be sick. I took a patch early today and felt good on and off throughout the day. I don't want to make myself sick by using too much but don't want to feel like crap either. Any ideas?
