How do you spray buds with fiberglass? And why? Weighs nothing. Looks? What shitty pot grower has powdered fiberglass laying around and not a bag of sugar?
I've seen tons of contaminants in dispensary weed (exclusively dispensary weed, aside from some feathers, cherrios, cat hairs) but fiberglass? Nope. The hydro store has lots of shit that will ruin your bud to make it look "frosty", you can vape a lot of peoples buds and watch half the resin melt while the other half remains as hard fibers,but its not fiberglass. And weed doesn't grow over fiberglass in an undetectable way. It's be just like the cherrios and cat hairs you find in hippy bud.
Not saying people havent done it Im just saying with all the dumb shit I've seen done to buds that would make them feel like smoking poison, since moving to AZ, fiberglass is not one of them. I've seen people admit to grinding up scheduled psych drugs in water before, so anythings possible in this fucked up world of greedtards
