Cannabis whets appetite for cancer patients
People with advanced cancer said food tasted better when they took the active ingredient in cannabis compared with sugar pills, a small Canadian study showed.
Cancer patients commonly report decreased appetite and changes in their sense of taste and smell that can lead to weight loss, anorexia, a poorer quality of life, and decreased survival, according to several short-term studies.
To explore whether tetrahydrocannabinol (THC) — the main psychoactive ingredient in cannabis — actually improves taste and smell perception and appetite, researchers in Montreal and Edmonton tested THC and placebo capsules in 21 adults with cancer. Of these, 11 were randomly assigned to THC and 10 to placebo.
Marijuana Compounds Could Beat Back Brain Cancer
Preliminary research suggests that a combination of compounds in marijuana could help fight off a particularly deadly form of brain cancer.
But the findings shouldn't send patients rushing to buy pot: the levels used in the research appear to be too high to obtain through smoking. And there's no sign yet that the approach works in laboratory animals, let alone people.
Still, the finding does suggest that more than one compound in marijuana might boost cancer treatment, said study author Sean McAllister, an associate scientist at California Pacific Medical Center Research Institute in San Francisco. "Combination therapies might be more appropriate," McAllister said.
Researchers have long studied the compounds in marijuana known as cannabinoids, which are thought to hold possible health benefits. One, known as THC, is well known for its role in making people high when they smoke or eat pot. Researchers have been testing it as a treatment for the brain tumors known as glioblastomas.
