Come on man. I can just quote the first sentence of wikipedia. "Tramadol, sold under the brand name Ultram among others, is an opioid pain medication used to treat moderate to moderately severe pain."
Tramadol and especially it's metabolite binds to the opioid receptor and works as a agonist.
Or you could do some research and see it was not originally classified as an opiate and was reclassified. Or you could have actual exp and know that all opiates do the exact same thing to the body given a high enough dosage you will get the opioid itch. At no dosage will Tramadol ever give you an opioid itch because it is not an opioid. Better yet I could tell you that bottles of Tramadol are in my house right now and have been for years not being used because again they are not opioids. How long do you think actual opioids would last in my house? 36 maybe 48 hours if there was a lot of them?
"When first approved in 1995, tramadol was not considered an opiate (like morphine or oxycodone) even though it acted in similar ways. However, because there were cases of abuse and addiction with its use, the thinking and warnings changed. In 2014, the FDA designated tramadol as a controlled substance."
I assure you Tramadol is not an Opioid I wish it was I would go pop a handful right now but it isn't
Perc, Vicodin, Nubain, Morphine, Oxy, Fent, actual Opium, Heroin they all do the exact same thing at dosage. Tramadol will not do it at any dosage you will never get the itch from tramadol it's not an opioid
