This pill is the generic
OxyContin 20 mg (Oxycodone 20 mg SR) manufactured by Endo.
I'm not totally sure on this one, but I think it is just standard controlled-release
Oxycodone. From the prescribing info at endo.com:
Oxycodone hydrochloride extended-release tablets have been reported as being abused by crushing, chewing, snorting, or injecting the dissolved product.
These practices will result in the uncontrolled delivery of the opioid and pose a significant risk to the abuser that could result in overdose and death.
