After discovering exactly how humans’ CB1 receptors operate, a team of chemists hope to bypass THC entirely, creating finely-tuned molecules that will trigger the receptors to send pain-relief signals to the body—without things like irritability, anxiety, or federal prosecution.

There’s no shortage of reasons to study cannabis—but federal law prohibits using anything but specially grown strains meant for research. There’s just one problem: lab weed is weak. The solution? A mobile lab that can accommodate real-life users and their real-life stash.

A cannabis high can be rather unpredictable, depending on strain, THC levels, and the interaction between hundreds of other these compounds. But as medical and recreational marijuana use spreads across the United States, how can law enforcement tell if someone they’ve pulled over is too high to be driving?

Your reaction to cannabis depends as much on your physiology and state of mind as it does on the plant. But science is always learning about how marijuana works on the human body—companies are figuring out ways to help you dose more consistently.

The recent legalization of recreational use in California may seem like a bonanza for marijuana farmers—but the situation is less peachy for small operators, who have to cope with a sprawling new bureaucracy governing the cultivation and distribution of marijuana. One company thinks it has an answer.
Sessions' War on Medical Weed Gets Public Health All Wrong
Using the opioid crisis to justify cracking down on medical marijuana isn’t just disingenuous, it’s irresponsible. Because weed is actually pretty great at managing chronic pain.

Not to Alarm Anyone, but Flesh-Eating Screwworms Have Entered the US
The USDA this week confirmed the first known infection of the carnivorous fly larva, which feast on the flesh of living mammals, after the United States eradicated the nightmare bugs in the 1960s.

Why Garlic Repels Mosquitoes and Keeps Them From Breeding
Garlic, as your grandmother may have told you, repels mosquitoes; it also completely blocks them from mating and laying eggs. Diallyl disulfide, it turns out, deserves the credit.
