This is the best summary I could come up with:
The researchers at Washington State University exposed rats and mice to cannabis vapor to stimulate specific brain regions associated with appetite.
Independent experts that DW contacted, such as Donald Abrams, an oncologist at University of California San Francisco, suggested the findings were a useful addition to existing research into the medicinal application of cannabis.
First, they observed the feeding behavior of the rats and mice and found that they looked for food more often after they had been exposed to that cannabis vapor.
But when those specific neurons are activated, it creates a cascade of neural signals linked to motivation and movement.
But the new research found that as soon as the mice in their study saw food, the hypothalamus activated significantly more cells with the CB1 receptor.
Michelle Sexton, a researcher at the University California San Diego, US, said that may have been because the drugs were taken orally, which may not be as effective as smoking cannabis.
