You made two of the same threads. The only difference being that this one has a poll. Just pointing that out, it might be against the rules, I'm not sure.

Anyway, I say conserve it. I wouldn't say smoke half, maybe a little more. That's what I would do. The most I've ever smoked at once was about 7/8ths of a 15 sack.

EDIT: Nevermind, I thought you were talking about smoking half of the ounce. As far as the nug, the size matters.
