Well it's rare that you will find a cigarette that has been used for months or years and never cleaned. They are disposable. The previous user put their mouth on that cigarette maybe 10-20 times.

The 'vaper' could've used that thing ten thousand times since it's last cleaning - if they ever cleaned it.

Also after that whole Vitamin E scandal - we found out some vapes can kill you. You won't find random cigarettes that will do that unless you live in Breaking Bad.

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.

Mainly food but I have done it for furniture. If you know the right places and know the right times, the food is fresh. Kolacheand bread are the best to get because they have to throw away what they don't sell that day, so it's always fresh and edible.
