I can guarantee you that no drug users were consulted in the making of this pharmaceutical industry patch program. (There is a great harm reduction document on fentanyl called “Injecting Fentanyl - Minimising the Risks.”) Illicit use by injecting, smoking or chewing eliminates the time-release function. The patch strengths typically went from 2.1 mg total per patch-with the patch’s time-release function meaning you get a dose of 12.5 micrograms per hour-up to 16.8 mg total, releasing 100 mcg per hour. The patches are meant to be stuck on the skin to release a certain amount of fentanyl into your body over 72 hours. They would range in price from anywhere from 50 Canadian cents to $2 a microgram. When I first started to inject fentanyl patches roughly eight years ago, they were all over the place where I lived in Halifax, Canada. The euphoric feeling that rushes through your body after you inject the warm burning shot is its own obvious reward. After it has been cooked, you need to dilute it with a little water before injecting. When you start to cook the patch, it slowly bubbles as the fentanyl abstracts. You put a little bit of vinegar on the spoon and stick the patch on the spoon.
Vinegar is not the safest method but I always found it the most effective. To get the fentanyl from the patch, you need to do a chemical abstraction. The odor of burning vinegar associated with the transdermal fentanyl patch will probably always be one of my favourite smells.
