Just swallow the Oxycontin, it's oral bio availability is high and you can't snort the new Oxycontins, and I'm not sure you can plug them either. Also, please do not try to inject these...
I hope you have an opiate tolerance, otherwise I'd recommend taking 25mg Oxycontin ER your first time, if it was instant release like a Percocet I'd only recommend taking 15mg your first time.
But, do not take the whole 80mg at once, I had a minor overdose on only 40-45mg my first time. 80mg with no opiate tolerance could result in a bad, possibly fatal overdose.
