The polydrug trade in the U.S. is on the rise. This is reflected in the composition of black- and gray-market cannabis. In one of the largest studies of its kind, we found that one in every five illicit cannabis samples in the Southwest contained cocaine, ecstasy, and methamphetamine. 💊🌿🧵 1/3

Cannabis & hemp are two biologically related but legally different plants.

Do universities have a future in Trump's plans to accelerate scientific discovery through the use of AI?
The recently announced Genesis Mission sets out to transform how science is done in the US. Yet it's a mission that places national labs—and not universities—in the driving seat.
