OK...so let me break this down....First, I'm going to assume for a dub you mean 2 grams and a 10 you mean 1 (maybe wrong).

You gave a dub (2g), another dub (2g), a '10' (1g), smoked a blunt (assuming a gram)...

So...a 6+ gram 8th.....not bad considering an 8th is 3.5g, and you made this post because you had no idea what an 8th was.

Maybe I'm wrong though....
