jessem,

i smoked cigarettes for years before smoking pot. i had dark/grey phlegm coming out in my morning shower. after i started smoking joints (mmc for IBS), my lungs felt better, but the stuff was still dark/grey.

then i quit smoking cigarettes. my phlegm turned from grey to green (i'm high 24/7) and my lungs started feeling even better.

anyhoo, my 2 cents is that if your phlegm is dark/grey, its NOT the pot.

i hope this helps...

memetics Reviewed by memetics on . Black/Grey Pieces in phlegm Me and my buddy are pretty much daily smokers. Now i smoke around the same amount as he does. Over the past year or so he has developed phlegm in which he coughs out, and it contains like black or grey little pieces in it... He has asthma, and his dad smokes like a chimney (in the basement away from everyone). He stopped smoking all together, and started vaping... Is this from holding in hits? Is it from exposure to cigs? ... Does anyone else have or heard or this? What could that Rating: 5
