Wolfman, as long as it's not gooey, it's smokable. And when it is all gooey, I'll just roll a ball of it in some weed ash. Makes it a lot easier to handle.

Normally, you can just fish around aggresively with a paperclip, and big ol' chunks will start to fall out. Those are fine and smokable. Don't be frightened when it sizzles and pops a little.

Also, when smoking it, use a screen. They melt a little, then turn into hard ash balls. If you have no screen, they go through when they melt.
