I once farted and it STANK of Weed, I have no idea how, hadn't eaten it before at the time, And I'd smoked the day before, All my farts smelt like that for a while on that night, really strong skunk smell (don't look too deeply into that, i'm talkin buds!) This was ages back , about 2 years ago.

I've done it since but it wasn't as pungent but still definately strong smell of cannabis- reeaally strange!!

and before anyone asks; No I don't smuggle weed
