Really, it could happen to anyone.
You could conceivably get very stoned and hide your marijuana in a really great hiding place. Then, the next day, when you are not stoned, you might forget where that really great hiding place is.
But it could be worse, because your whole upstairs might stink like weed, and your children might have had that stupid drug education class where they liken marijuana to heroin.
So you could be airing out your house on a very cold day, searching for a stash of marijuana that you can smell but you can’t see. Apparently you can hide things very well, but you can’t seal a ziploc bag.
But I’m not saying it happened to me.
