When I puff, I cough out the phlegm. If ever I don't puff a day, the cigarettes clog my lungs back up and the weed spews it back out. But all day, it's like an ebb and flow process. Cigarette tar in my lungs I'm coughin' back up after a bowl. My girlfriend told me that it was parts of my Lungs. I asked her if she thought it was Section 1 or Section 2.
