I thought this might be it, but it doesn't match the data - FDA says fentanyl is about 100x more potent than morphene. Assuming this matches the ED (a big assumption), the ED of fentanyl would be .0024 mg/kg (or 1/100th of morphene), and the TI to be 1.25. But such a low TI can't be right... can it?

Thanks for posting the source. Weird that you're having trouble posting links, though. Regardless, I was hoping you might be able to help me find the info inside of a source. I was surprised to see that the TI of fentanyl was 7x that of alcohol (given the fear mongering), and I couldn't find the ED-50 on the DEA's website. It's possible I missed it - could you identify the paragraph on the DEA's website that talks about the ED-50 of fentanyl? I'm kind of surprised they'd give out that info, to be honest.

I noticed that the ED-50 of fentanyl was italicized - does that mean it is perhaps not listed in the source provided?
