i use a callous file (the metal portion only) to make the pill a powder.
leave it in a pile the size of a quarter on ceramic plate, microwave until golden/lite brown. keep an eye on the shit, for real.
allow to cool, scrape up material.
chop finely, combine with inert powder or whatev. and enjoy.
and yes, they will work for IV when prepped properly like this. i tried, it worked.
