Here is what u need for some stealth indoor smoking of the jay. I usually dont smoke jays myself but this method should still work.

U need a Small fan ( one that you can set on a window seal)
Your own room
Curtains


Place fan into window , close curtains all the way around fan , so nobody can see in . Now we should have a fan blowing out the window . Spark up the jay and smoke behind this fan , blowing hits into the back of it. Hold they jay close to the back of the fan while your not smoking so that the smoke its letting off is gettin sucked outside. You won't get caught this way , but it does kinda take the relaxation feeling associated with smoking jays. But best of Luck bro.
