Specifically, shatter that’s higher in tetrahydrocannabinol (THC) will tend to be sappier than a product with a higher level of tetrahydrocannabinol acid (THCA), which will be much more brittle by comparison. At room temperature, THC is a sappy oil, giving shatter with a high THC content a more viscous consistency, whereas THCA is solid at room temperature, yielding a fragile concentrate that’s easier to break apart.
