You had paper, LUXURY. All we had were leaves, and the most common were either poison ivy, castor oil bush or thistle. If you were lucky you got nice soft palm fronds.

Of course when I say cigarette papers I meant dried up pieces of leaves coated in razor sharp prickles coated in cyanide

You had tobacco? All we had was dried out buck droppings, if the dung beetles did not get to them first. Wrapped in dried out leaves and then if you were lucky you had some piece that was very grassy to act as a filter.

Lit with an ember from the fire, which you had to keep going or else you had to knap flint or use a fire bow to restart it.

Only thing we had plenty of was dry sand.

Luxury, you had tissues, all we had were used cigarette papers......

and you tell the kids today and they wont believe you

These kids will have their own 'when I was at your age' stories to their grandchildren. For example, I had to route manually my PCBs and then wait a week (!) for them to arrive.
