That's insane. Tramadol is among the worst painkillers to use recreationally, which is why it's often the next line of analgesic therapy after NSAIDs and before hydrocodone.
It is a comparatively weak mu-opioid agonist, so the dose a person would have to take to get a prototypical opioid high, likely quadruple a normal prescribed dose at minimum, is pushing the margin of safety.
I am not advocating drug use here, but if you're dead set on getting high, please use something else- namely something with a higher mu-affinity that would require a lower dose, and ideally something that's not combined with acetaminophen or other NSAIDs.
