French inhale, isn't that hard. For a beginner just fill you're cheeks with smoke, like a cigar. Then just open you're mouth and breath in through you're nose.

Smoke rings are easiest when the cheeks are filled not inhalled. So instead of waisting weed. Just grab a cig or two, you don't have to inhale. Just fill you're cheeks with smoke. Then make a tight o shape with you're lips. Keep you're tongue flat on the bottom of you're mouth. Then gently let a couple smoke rings out.
