That brown shite is your lungs cleaning themselves, it takes time. Good job though mate, quitting cold turkey takes discipline.

Stoner here. I take a 3 month long break every year. Go running. Seriously pick up running/jogging and keep amping up the intensity. Youll be surprised how much this helps you hack it all up.

This. Hard cardio forces the lungs and airways to create mucus - the mucus is there to deal with the increased air intake and trap/filter out all the dust and pollen and crap that comes with it. All of that debris gets stuck in the mucus, which you then expel from your lungs by coughing it out.

Extra mucus will help dislodge all that tar bullshit. Keep in mind youll never get it all - you permantly damaged your lungs. But youll probably get most of it, meaning you should be able to get the majority of your "natural" lung fuction back. So yeah, cardio. Be ready to cough so much shit up that you want to puke lol.
