Marijuana

​The legalization of recreational marijuana in some US states has resulted in a giant new multibillion dollar industry. The latest THC-innovation comes from a Californian winery that has created the world’s first alcohol-free, marijuana-infused Sauvignon Blanc.

The ONUSblue alcohol detection patch tells you when you've reached the legal threshold and has the potential to save millions of lives. The company's product roadmap is even more interesting with the detection of marijuana, methamphetime and a range of illegal recreational substances to follow.

FreshAir's AirGuard uses sophisticated polymer technology to detect and rat out illicit tobacco and marijuana smokers. Targeted at the hotel market, AirGuard could also be a big hit in workplaces, public housing, college dorms, jails and anywhere else where smoking is restricted.
