I can blow smoke rings of dif sizes and shoot them out slowly or very fast. I havnt been able to blow a bigger one than a smaller one thru it... but still hoping one day to be able to do it. Yes i can also french inhale and snap inhale. Oh also with the french inhale I can do twice with the same hit.... like out my mouth then thru my nose and out my mouth and thru my nose again but althought it sorta has to be a big hit to do this so you have enuf smoke to last
