Lame, but I think biological nanopores are so beautiful, and nanopore sequencing is cool as hell!

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.

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.

I totally agree with you re: disposing of the end of the cigs. But when you’re outside, do you have an issue with the ash aswell?
