So I couldn't find any actual studies about Fentanyl. But I did see plenty of personal accounts that once people used it for weeks or months they could no longer get high off of less potent opiates such as Hydro, Oxy, or Dillies. Does anyone have any studies on the effects of Fentanyl on opioid tolerance? Would using once negatively affect my tolerance or would I have to use repeatedly?
