OAKLAND (CBS SF) — A new breathalyzer being tested by law enforcement, not only can tell them if a person has been smoking marijuana, it can also tell if a person has eaten anything laced with marijuana.

Wednesday, Oakland-based Hounds Labs, Inc. announced it was field-testing a device called The Hound that can detect tetrahydrocannabinol (THC) the active ingredient in marijuana after consumption of both smoked and edible pot products.

Stanford engineers have made a similar device dubbed the ‘Potalyzer,’ but it only detects smoked marijuana.

Both devices have drawn praise from law enforcement agencies.

    How about a road side test for the 100s of Big Pharma chemicals that are all far more impairing than cannabis?
