Ugh I hate to advocate this but cut a small corner off the patch a squeeze a very small amount on a piece of tin foil. Hold a straw above and light from the bottom. This is literally the smoking crack of opiates. When I had a huge access to them, I could smoke a 100mcg patch in 3 hours. Also after all the gel is gone cut one side of the patch off and cut each side into 4 or more pieces and shove a single piece into your cheek and that will last for awhile. Pharmaceutical fent isn't as potent as street fent, but it's still dangerous so please try to be careful. Do not try to shoot the gel you will die. I don't know how much tolerance you have but please take it slow. As for selling them, it's a niche market and unless you find someone that is specifically looking for patches, you won't make decent money.
