Oxycodone is a very powerful and potentially addictive opioid analgesic medication synthesized from thebaine. It is similar to codeine, but is more potent and has a higher dependence potential. Also, hydrocodone is a cousin to oxycodone, in that it aids pain relief. I'm not quite sure which is stronger, but I do know that a small pill of either medication can really mess you over - two pills can get you in to "happy land" and probably make you sick, as in you will throw up. If you do throw up, then guess what that means. You just put a poisonous amount in to your body.
If the person taking pure oxycodone or hydrocodone and is not in severe pain constantly, then I'd recommend they stop using it - it's long term effects can be nasty.
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
