There is, you can get something like NORSPAN which is an opioid analgesic (uh topical patch) but as far as I know you have to specifically formulate for it.

Yeah. It has to be formulated differently for both gaseous and transdermal applications. Fentanyl is infact available as a transdermal patch that absorbs through the skin.

In addition to this it's been used for decades in gaseous formulation as general anesthesia during surgery. General anesthesia is what a majority of pharmaceutical fentanyl gets used for and it's fentanyl that tends to be what kills people when anesthesiologist fuck up. Famously Russian special forces used the general anesthesia formulation of fentanyl to gas a theater during a hostage situation and ended up killing a bunch of hostages.

it's believed they used a vastly more potent analog though

Yeah, it was carfentanil. The large animal veterinary formulation used to anesthetize elephants and rhinoceroses. Carfentanil has 20 to 100 the potency of fentanyl, which is why whenever idiots steal some from veterinary supplies cities end up with an uptick in overdoses.
