Are they aware that a 9 bar is the standard unit of weight for buying ganja? to be precise the resin called soap bar is so named because it comes in cellophane wrapped bars roughly the size and shape of a large bar of soap. Each weighs 9 ounces because that is roughly 250g, or 1/4 of a kilogram. Almost all weed, even the green stuff, is sold in 9 bar weights because of this. Every child over age about 10 knows this, very odd way to promote your product.
Perhaps the late night munchies market is the niche they're trying to tap into.
