My first time inhaling (didn't do it right until 3rd time smoking) sucked balls and when i came back from a 2 yr break it sucked just as much. There is an easy way to do it tho; have ur jaw up with as little air in you're mouth as possible suck all of the smoke into ur mouth by bringin ur jaw down. Then inhale through ur nose, while slowly making the area in ur mouth smaller by bringin ur jaw back up. The slower u go the easier it is. Lastly clear your mouth of the remaining smoke by opening ur mouth and takin in a huge breath until you completly fill you're lungs. Then exhale normally. Some people tell me this "waters down" the weed but I don't notice a diffrence. You know if you did it right because the smoke won't come out for a second. Also smoke thats inhaled looks is alot diffrent then smoke that just sits in ur mouth for a second or to even if you don't use my method this is a good indicator of doing it right.

Ugh wish some one explained this to me before i figured it out my self by pondering how bongs worked.
