Best opioid……HANDS DOWN would be Eukadol (Oxycodone)
What Hitler loved most, says Ohler, is a drug called Eukadol, an opioid known generally as oxycodone. Synthesized from raw opium, it had twice the pain relieving as morphine. Ohler writes that it achieved “a euphoric state significantly higher than that of heroin.” In addition, Morell would combine Eukadol with cocaine, creating what we now call a “speedball,” the combo that killed John Belushi.
I’ve done every opioid, every ROA and high dose IV ……even ORAL Oxycodone blows any other opioid outta the water…..I still remember the warmest blanket of euphoric bliss, emotional & physical comfort and security, unlike its sedating counterparts ….Oxycodone synthesized from theBaine is actually slightly stimulating and uplifting, social butterfly, but the overwhelmingly powerful euphoria was insaine
Oxycodone & Ritalin (Methylphenidate) is my oral Speedball or choice, both are extremely euphoric ….plus ethanol while the onset of action is occurring with all 3 compounds…….simply wow
