The use of shake is a widespread practice, and it ensures that all of a dispensary’s flower is put to use. But it can also ruffle feathers. Some consumers think shake is low-quality cannabis, which isn’t necessarily the case. In essence, shake is just smaller pieces of the same quality stuff.
But there are caveats. Shake can be of low quality if it’s dry—usually the result of jars sitting out too long—or if it contains stems and bits of leaves. And sometimes shake from various strains can be combined when making pre-rolls (sometimes called mystery or rainbow rolls). There’s also a bigger problem: Trim masquerading as shake. Before buying a bunch of pre-rolls, it’s not a bad idea to sacrifice one and cut it open. The contents should look about the same as if you’d ground up a new nug.
