The term “shatter” is derived from the fact that the leftover resin is often cooled into a glassy sheet, similar to boiled caramel hardening into candy. When dropped, the sheet — surprise — shatters. On the street, users are more likely to buy it in a thick, taffy-like form that typically sells for $60-70 per gram.
Of all the concentrates, shatter is the most potent — it goes through an additional filtration process to get rid of other naturally occurring fats and waxes — which is how it manages to pack its active ingredients in crazy high amounts (regular weed, when smoked, only has about 5-18 percent cannabinoid content). While this extra step optimizes purity, it also filters out the dank hydrocarbons known as terpenes, which make up marijuana’s flavor and scent.
