Colorado's retail marijuana is high in THC, low in CBD


No one is surprised that weed in Colorado is high in THC, but low in CBD (cannabidiol). It is, after all, a state where recreational use is legal. CBD is one of the compounds known to have medicinal properties.

The lab responsible for this testing "also found some contaminants in retail pot samples, including fungus and the chemical butane, which is used in making marijuana extracts… whether that's any cause for worry, however, is unclear."
