After my dad died, I searched the house for the rest of his hidden stash but with no luck. Then a year later I was showing some friends where I had looked, and found his weed that I had missed (it'd been only a couple more inches out of my reach)

There was a joint and some leftover shake, loosely wrapped in a plastic baggie. It smoked just as good as any other average joint I've had, and it was schwag.

Some strains can get more stoney over time I think. I once found some trim leaves in my dehydrator that were over a year old. Burned it all down in only one small hit and got super stoned for 3 hours!
