I have the HOT Juice, and it really only smokes on the new level 5 (level 6). Only a quick puff on the other settings. I actually prefer it! It's one reason I haven't picked up a Smarty yet. I want to be able to control the smoke.
I know that everyone thinks it's "cool" for tons of black smoke, and I do too, but only when I am playing around, not for daily driving.
