When I first started smoking I would try little fancy tricks like french inhaling and smoke rings to try and impress my buddies and not look like such a novice smoker. After a while I just kind of stopped with the tricks and just smoked the shit. The only thing I do now is just hold each hit in my lungs for a few seconds. I have no idea if this gets me higher quicker or anything but it seems like it does so I do it.
