oxycodone and weed?

ok i have done opiates before, actually in the summer i grow my own

but a friend of mine gave me some oxycodone (rixocet) I myself am a fan of snorting and want to know how much i should face the first time. and would it be ok to smoke weed while i am on it?
and is it like other opiats? like same type of feelings?

and please no erowid, as i find most of the information here generic

its roxicet right?... if you dont smoke do 30-50mg and smoking weed will totally make the high like twice as good.. your going to nod so hard. im jelous.
and if you get natious dont try to hold back the puking... embrace itttt youll feel SO good after. i love opiates.
