What is the Best Way to Hide the Smell of Marijuana?

But a new study that has just been released reveals that there’s something else that works: vacuum-sealed plastic. A team of researchers at the Colorado State University studied the ability of untrained subjects in identifying dried cannabis flower based just on its smell, when hidden in vacuum-sealed plastic. “Open and casually packaged cannabis was identified with high accuracy, while material packaged in doubly vacuum-sealed plastic was correctly identified at rates no different from chance,” they reported.
