I know that the active ingredient in both oxycontin and percocet is oxycodone. would that mean that a 10mg oxy and 2 5mg percs have the same exact effects? and as for taking oxycontin, is crushing them really necessary? can SWIM just swallow them whole instead, and still get the desired effect? I am sorry if these are stupid questions. She is VERY new to opiates (and drugs in general)and is still learning about them.
