is it possible to do this? someone told me they had a friend who dissolved the inner medicinal core of a tablet after breaking it and injected it... is that safe?? is it possible?
it is certainly not safe. these meds are designed to be ingested orally. they may contain binders and fillers like silicates or chalk, and these could result in nasty infections if introduced into your veins. There is no safe way to inject or insuflate a pill intended for oral use only.
