i'd just like to point out that ohmefentanyl has an isomer f that is kx morphine there is also an siomer mixture of ohmefenanyl that has a reported potency in the region of kx morphine more recent studies point to analogue such as fluoro omf that is even more potent perhaps a new section needs to be opened up to clarify this as clealry there are is some controversy over the strongest opioid or at the very least we are not clear on the issue
