Would you scrape mildew from the grout of the tiles in your bathroom and smoke it?

That's a really bad idea, I don't think anyone in their right mind would sell someone moldy weed. Unless it's VERY little mold and you can pick it all out...even then...You can get VERY sick. Moldy weed gave me pneumonia, I was in bed for three weeks struggling to breathe...

Don't smoke it! You'll get REALLY sick if you don't die.
