Generic medicine is often made by several different manufacturers, they each make their own formulations, composed of different binders and fillers. Mentioning of which manufacturer SWIY has their product would be useful for others to determine what would work best. But smoking pills in general is a bad idea, since they contain all kinds of materials which can decompose into toxic byproducts after pyrolisis(combustion). If one wishes to smoke pills, than don't actually smoke them, but try to vaporise their active ingredients by grinding up the pills as fine as possible and vaporise them on some aluminium foil, or in a lightbulb vaporiser.
Since the only Oxycodone
knows and has had are brand name OxyContin and OxyNorm, he can't help SWIY any further. But posting the list on fillers and binders SWIY's pills contain could be of further use, helping to decide if it would work or not.
