Fentanyl is a very dangerous drug and you really don't sound like you should be messing around with it if you can't take a few minutes to do some research on something that can be so deadly. If you decide to do it I personally think smoking it is the safer way (as opposed to bucally) because you can smoke little bits and know if you can handle more or not in 5-15 seconds. The way I smoke it, is I take a piece of the patch and hold a corner with pliers, then I stick the sticky side on foil. I then light a lighter underneath the foil for only a second at most and pull the piece off with my pliers right away.
Really though... You should take a few minutes to look into what you're dealing with instead of just taking a couple random people's word on it. Really man, try to be a little smarter. I know taking 20 minutes to look into the potentially deadly drug you're taking might be a little difficult for some people, but do your best... It's not worth your life. I was in front of my comp for a good 3 or 4 hours the first time I fucked with fent. Just be careful.
