Kush in Sierra Leone is quite different; it is a mixture of cannabis, fentanyl, tramadol, formaldehyde and – according to some – ground down humans bones.
Yeah.. that’s insane. I recently had surgery and was administered a small dose of fentanyl via IV while being held in post-op, I was also prescribed tramadol for pain management afterwards. Both drugs turned me into a zombie on their own. I can’t imagine mixing both, and also layering on weed, as a recreational substance.
If there are both, you won't feel the tramadol. When the ratio is high enough, it will make it suck less when the Fentanyl wears off and give it longer action though. It's kind of like saying they smoked meth with cocaine sprinkled on top. The meth is doing the heavy lifting.
