The stereotypical cannabis connoisseur perpetually has the munchies but is, paradoxically, perplexingly thin.
Now researchers at the University of California, Irvine, think they know why—and no, pot consumption isn’t the secret to a svelte figure.
Not a healthy one, anyway.
Frequent cannabis consumers are leaner and less likely to develop type two diabetes. But the pseudo-health benefit comes at a price, researchers assert in a June 2 article published in Cell Metabolism.
Many cannabis consumers begin use during their teenage years. Realizing this, researchers gave low doses of THC—tetrahydrocannabinol, the main psychoactive component of marijuana—to adolescent mice. Once the mice were fully grown, they stopped the doses, but the damage was done.
Drug-free male mice that had consumed THC as “teens” had reduced fat mass, increased lean mass, had higher-than-average body temperatures, and were partially resistant to both obesity and hyperglycemia. They were in what researchers referred to as a “pseudo-lean” state.
But they also had a reduced ability to use fuel from fat stores—a consequence that can interfere with tasks like moving and thinking, and especially sustaining attention, researchers found.
Similar features are seen in some humans who are frequent cannabis users, they remarked.
“All too often we think of cannabis only as a psychoactive drug,” said Daniele Piomelli—one of the study’s authors, director for the university’s Center for the Study of Cannabis, and professor in its School of Medicine Department of Anatomy & Neurobiology—in a news release on the study. “But its effects extend well beyond the brain.”
The reason for these permanent changes surprised the study’s authors. Once exposed to THC, fat in the mice’s stores began making proteins normally found only in the muscle and the heart. Meanwhile, their muscle cells begin making fewer of the proteins they should. The effort required of fat cells to make these “alien” proteins interferes with the correct, healthy functioning of fat cells, and their ability to store and release nutrients, researchers concluded.
