(Phys.org)—California based Hound Labs Inc. is claiming to have made a breakthrough in the rush to develop a portable device capable of detecting THC, the active ingredient in marijuana, in the breath of someone that has recently smoked a substance containing the chemical. They claim also that their device will soon be small enough for use by law enforcement to remove impaired drivers from the road.
