Is it that much of a pollutant? Again just ash, I'm always pretty conscientious to dispose of my filter tips, but never thought the ash was a problem. Does it severely damage plant life? Is ashing in a concrete carpark more acceptable?
Not trying to get facetious here, genuinely trying to find out more.
Okay, but are their heavy metals in the ash or just the tips? I use paper tips so I don't think there is any heavy metal in them, but if it's in the ash then that's different. Thank you for looking into it tho.
