Does snorting Oxycontin make the product work faster?

I have been worried about my brother because he has been crushing up the pills and snorting it or mixing it up in his morning coffee. He suffers from chronic back and neck pain and swears he does it thay way to speed up the pain relief. He also takes oxycontin that is time released but only crushes up the oxycodone. He does not take more than the doctor orders. Can snorting or drinking this medication be harmful to him?
