I'll ask the guy that has them. He'll know. They have a
grey coating on them, which I'm sure would have to be scraped off.
He also gave me a dilaudid (sp?) which I'm pretty sure I could have
shot as it was white and had no coating. No idea how much of it
to shoot and forgot to ask and anyway I was travelling and had no gear.
BTW, eating the dilaudid was a mediocre, tho more potent, experience than the morphine
tabs and I'm told it's killer to shoot.
