thecreator Reviewed by thecreator on . How good do "lungs" work? I've realized that I like trying out new smoking methods and I haven't tried out the lung so far. It's fairly easy to make one, in fact, I just made one from a 500ml Naya water bottle and a medium sized Ziplock bag. I'd like to know the following: 1. How efficient are they compared to a bong or GB? 2. Do they leave a strong smell? Comparable to a joint? Bong? 3. Your experiences with lungs. Rating: 5
