Ever Wonder How They Test Marijuana For Safety? (VIDEO)

Posted: Updated:

As marijuana goes mainstream in the U.S., people are asking new questions about weed. What makes some marijuana especially potent, for example, and how can marijuana be regulated to make sure legal weed doesn't send them on a bad trip?

For answers to those and other burning questions about the chemistry of cannabis, have a look at the new video (above) issued by the American Chemistry Society as part of its Reactions You Tube channel. The video explains how marijuana's active ingredient, tetrahydrocannabinol (THC), affects the brain, and how the marijuana-testing labs now springing up across the country test pot for safety and quality control.

To learn all the tricks of the trade in marijuana labs, check out the video.
