Nah, I'm kidding man.

It;s easy, fill your mouth with smoke, open your mouth, and slowly release the smoke in your mouth, push it out using the air in your mouth (kinda hard to explain), and while you are pushing the smoke out, inhale through your nose.

It will take some practice and is major hard to describe with words. But it's basically getting the smoke from your mouth, up, into your nose. Practice, you'll get it
