I’ve taken cigarette dimps from the floor.

Other random things. I tend not to smoke joints to the roach and then on hard times I had been known to tear up all the 10% joints to make a nasty one.

Finally, I lived in some rough ass flats once and the junkie neighbour would often knock on asking to bum a smoke. I would always oblige if I had some but one time I didn’t. He proceeded to ask for some of the ash from my ash tray. Dumbfounded I’m like sure. My sociopathic gf at the time enlightened me that it was to facilitate smoking crack as the ash would aid the burning of the rock.

I’ve seen crack heads roll up on a pub with a shopping bag and empty out the ash tray things attached to a wall and get off.
