It's not a different chemical compound, it's all Oxycodone, it's all the same abuse potential because it's the same drug. The current extended release formulation IMO is inferior to the old formulation of OxyContin. Long acting opioids aren't less habit forming, but the reason doctors say that is less "addictive" is because it is supposed to maintain steady levels of oxycodone in the blood vs. a pure instant release formula which has more "peaks and valleys".
This doesn't make oxycodone a different drug, it's all the same chemical, it's equally addictive. The only thing that's changed between the old formulation and the new one is that a different time release mechanism is employed, the new one is tamper resistant but is attempting to mimic the old 12 hour time-release, they didn't change how long the medication lasts, it's always been 12 hours.
The logic behind my argument is that a person taking oxycontin regularly will still gets physically dependent on the medication, I mean if you've been prescribed OxyNeo you should know that if you don't take your medication you get withdrawal symptoms.
I think that we're using the word addicting here but I think we mean habit-forming, which means you're taking it for legitimate reasons but your body is dependent on it, just like anyone who regularly takes opioid narcotics.
