Never. Sure maybe small amounts of second smoke may make its way into my lungs but not enough to notice. It seems just about everyone knows someone that thinks smoking any kind of tobacco includes intentionally inhaling. I gave a friend a chance to experience a La Herencia Cubana OF and he ALWAYS inhales it.
His father used to smoke about 5 years ago and did the same thing. Needless to say I won't have to worry about them asking for a stick from me.
