Not so long ago, crippling nausea and vomiting were routine for people undergoing chemotherapy. But thanks to new drugs and other treatments, that isn't the case anymore.
"We've made great progress," says Karen Syrjala, PhD, director of biobehavioral sciences at the Fred Hutchinson Cancer Research Center in Seattle. "We have much less nausea and vomiting now -- even though we're using much higher doses of chemotherapy than we did before." Because we can control the side effects, Syrjala says cancer treatment itself is much more aggressive.
Cannabis, also known as marijuana, is a plant grown in many parts of the world which produces a resin containing compounds called cannabinoids. Some cannabinoids are psychoactive (acting on the brain and changing mood or consciousness) (see Question 1).
The use of Cannabis for medicinal purposes dates back to ancient times (see Question 3).
By federal law, the use, sale, and possession of Cannabis is illegal in the United States. However, a growing number of states and the District of Columbia...
Antinausea medications -- or antiemetics -- are so effective, that experts have shifted their focus from treating nausea to its aggressive prevention.
"My standard goal is to stop nausea before it happens," says Christy Russell, MD, chair of the American Cancer Society Breast Cancer Advisory Committee, "rather than waiting for it to start and then treating it."
Of course, not all cases of nausea and vomiting can be prevented -- 70-80% of people on chemotherapy still face some risk. But thanks to better treatment, most people in chemotherapy are able to go about their normal lives, working and caring for their families.
"You may not feel great all the time," says Carmen Escalante, MD, chair of the department of general internal medicine at the University of Texas M. D. Anderson Cancer Center. "But you can keep going. And that's a big improvement on what chemotherapy used to be like."
