I take my hit, and breathe in as much air after the hit as I can to ensure that there is no smoke in my esophagus anymore. Once my lungs are full, i hold for as long as I can without coughing. Sometimes I try to hold it too long and start coughing before i can even exhale. Then I'm real baked.
Joints, blunts, bongs, bubblers, steamrollers, waterfalls, gravitys, spoons, vapes... I love em all!!! But my daily smoker is a bong made out of a goldschlager bottle.
