Huh? What comment are you referring to? I didn't call fentanyl and similar analogues "just another opiate". (Also, fentanyl is an opiod. It is not a natural opiate. And diacetylmorphine, thanks to its improved lipid solubility compared to morphine, has an approximately 70% brain absorption rate. That's not "modest".) Your reply really confuses me.
