PULLMAN, Wash., Sept. 3 (UPI) -- Tolerance to THC, the main psychoactive ingredient in marijuana, is different in male and female rodents, according to researchers at Washington State University. Their study showed female rats are more sensitive to pot.
According to the research, female rats were found to be more sensitive to the pain-relieving qualities that marijuana offers. They were also more susceptible to the drug's negative side effects. Researchers say similar differences are likely to exist in human smokers.
