How cannabis affects appetite: Brain changes

“We found that cannabis exposure caused more frequent, small meals,” stated Davis. “But there’s a delay before it takes effect.” That delay provided a clue to how the drug may act. Ordinarily, when the stomach is empty it releases a hormone called ghrelin, a message to the brain that it’s time to look for food. The researchers found that the cannabis dose triggered a ghrelin surge. When they gave a second drug which prevented the ghrelin surge, cannabis no longer triggered eating. They also found changes in how the brain responds to the message. In small region of the hypothalamus responsible for sensing ghrelin, cannabis changed the genetic activity of brain cells that respond to the hormone.

Hopefully we can start developing a pill or inhaler for terminal patients and cancer patients to help them with their appetite. :slight_smile:
