That i like to roll and sniff a tar ball i coughed up.

Hi years ago i coughed up some mucus. Usually I keep it untill dry and roll and just dont last, i get many diff types. I always had sinus issues so get mucus. I think it odd but. I gave up smoking like 7 yrs ago and this one time it is black and smells odd well was darker green but changed once was worked and dried. I think it is tar lol.

It lasted years and has odd texture when rolled and seams grow in size over time. It seam change consistency some days it soft others it tries to go crumbly and split seam have a fibre starnd texture some days.
My bro has rolling habit but with blu tack. Am i only person? also i like rubbing labels
