This Lab Is Making Sure Your Legal Weed Is Safe to Smoke

We visited a lab that tests weed for harmful contaminants to find out if a batch of cannabis is OK to consume.

If it's not handled properly, weed can collect toxins, pesticides, and other harmful chemicals that can have long-term impacts on your health and well-being, an issue that can put legal markets in jeopardy.

On this episode of Daily VICE, we meet Dorian Des Lauriers, CEO and founder of ProVerde, to hear how his lab tests weed in Massachusetts for harmful contaminants. Using mass spectrometers and powerful microscopes, ProVerde screens weed for bacteria and mycotoxins to make sure it's actually safe to smoke.
