So I have not had a pipe in three weeks. I smoked 10 plus bowls a day but I have been sick since last fall. I have been to a couple of different dr's. After a battery of test they swore it was my gallbladder. but nope liver and gallbladder are good to go. No they "think" its COPD. I have one more week til I see the pulmonologist I have started and daily inhaler for COPD and I am seeing a little improvement but dont want to ruin it with a pipe so I have to wait a bit more
