There is no safe or energy worthwhile method for breaking the OP time release, so don't.
Yes, contrary to popular belief, taken orally they should be almost as good as the OC's. If you got euphoria from the old OxyContin you probably will from the current standard one that has been in place for several years now.
This thread has no HR value so I'm closing it. The only thing about the oral ROA is you need the tolerance because it is A) the way the tablet was (or it used to be...) designed to work best as they formulated it. Trust me. Purdue does not want to cock-block you from getting high. They have made their motives quite clear in the past, we all know they're in it for the money, they don't care about anything else, they don't care if the people using the drug have a prescription or not, so long as the tablets get sold and the quotas are made and the shareholders are happy.
They are the ones who lied about it's abuse potential in the first place, they want/wanted as many people to get addicted and stay addicted to their products in their semi-monopoly patent-wise in the oxycodone ER pharmaceutical industry.
